Do-it-yourself sectional garage doors. The best tips for installing sectional doors with your own hands. Materials for the manufacture of sectional doors

Modern garages for cars are significantly different from those that were built before. First of all, the design itself has changed. After all, if twenty years ago, a garage was needed only to simply store the car from adverse weather conditions or theft. For current motorists, given their feedback, it is almost a second home with various car amenities.

Sectional garage doors are considered an essential detail of this change. The huge swinging metal or wooden models have been replaced by comfortable, beautiful and excellent quality standard electric gates. Moreover, their designs can solve a very important problem of lack of space.

The most popular novelty is considered to be overhead sectional doors, which maximally combine all the advantages of "relatives" and, which is very convenient, are equipped with an electric drive.

Many car owners, in order to save money, decide to make sectional doors with their own hands. It is no secret that this task is not easy. The purchase of a ready-made factory kit will help to solve it. Its owner will be able to independently assemble and carry out installation if the garage sectional doors have the correct dimensions.

Purchasing Parts

In order for the design to be as strong and reliable as possible, in no case should you buy parts for it in the markets. As a rule, a factory kit is always sold with a step-by-step assembly system. If you carefully study it, prepare and follow the instructions exactly, then installing a garage door with your own hands is greatly simplified.

How to prepare a doorway

Before you install a sectional garage door, you need to prepare a doorway. To do this, you need to correctly determine its dimensions and how well standard canvases will become there. With the help of a level, it is necessary to check that the surfaces of the opening are on the same plane. Both the vertical lines and the upper part adjacent to the ceiling should be parallel with the floor.

All these works must be carried out with your own hands during construction in order to avoid additional work before installation. If the parameters are correctly determined, the subsequent adjustment after installation will be minimal.

You can find out the dimensions of the depth of the room, which is necessary for the installation of sectional doors, based on the height of the doorway. You need to add 50 cm to it. When installing a gate with a drive, 100 cm is added to the height parameter. When building a garage, you need to use very durable materials, otherwise it will be very difficult to reliably install the sectional door structure with your own hands.

When drawing up a garage construction project, you need to remember that the optimal dimensions of the lintel are 25-50 cm. Reviews of experienced garage owners will confirm this. If this is not taken into account, then the design will be much more complicated, and as a result, much more expensive. To create a good fit for parts of the garage door, as well as to improve thermal insulation, the doorway with your own hands must be leveled and plastered.

Standard sectional doors with electric drive consist of the following main parts and mechanisms:

main canvas;
guide modules;
mechanisms for spring balancing during movement;
arrangement of mechanisms for movement by electric drive;
standard locks.

Therefore, after the installation of sectional garage doors is completed, they can be driven electrically using a remote control.

Features of installing garage doors with your own hands

Sectional doors consist of sections connected by hinges. Tires are attached along the edges of the opening, which go under the ceiling. It is on them that the sections move. When the garage opens, they roll up and are placed at the top.

The panels can be chosen to the taste of the motorist, but it is advisable to read the reviews before purchasing. Both pattern and color are very diverse. The factories that make them offer many options. The polymeric covering reliably protects them from undesirable effects of corrosion. Sectional doors are equipped with special thermal insulation panels. Therefore, they work well and silently at any temperature - from -50 to +60 degrees.

There are some rules that it is advisable to follow when installing sectional garage doors:

When working, use special drawings;
Work with high-quality materials, and only factory production;
Calculate dimensions as accurately as possible;
Carefully place the details, try to do it accurately and correctly.

Starting the installation with your own hands, you need to understand that this process will require a lot of effort and patience. One person cannot do this kind of work. Therefore, you can call friends for help, preferably those who are well versed in such work. After all, even using the instructions, it will be incredibly difficult for one person to determine the dimensions and draw up the drawings correctly.

We should not forget about caution. You can feel safe only by wearing a helmet on your head and gloves on your hands. And be sure to protect your eyes.

To do this, you can use special glasses. Before work, you need to check the presence of wrenches, screwdrivers of various types, a hammer, a level, a drill and a tape measure.

How to install sectional doors with your own hands

The scheme is very simple:

At the very beginning of work, you need to make a markup in order to establish the places for fixing the supporting elements. If the dimensions of the latter are slightly larger, you need to expand the opening.
Assemble the frame.
Next, this frame is carefully lifted and installed in the prepared opening. There is no need to rush into a strong fix. The frame may need to be adjusted.
Using bolts, you need to assemble and fix the horizontal rails and attach them to the ceiling.
Then you need to collect the canvas. Installation starts from the bottom. All panel elements are provided with rollers.
Work on assembling the mechanism for balancing the canvas.
Installation of handles at the bottom of the panel for comfortable use of the gate.
For protection, you need to close the mechanism with special casings.
Checking the quality of the installation. If everything is done correctly, then the canvas will be at the level to which it was raised. It will not fall by itself or rise involuntarily.

If you managed to make sure that the work was done correctly with your own hands, then there is a high probability for many years, or even decades, that you can enjoy the gate, which definitely does not require repair. It is desirable, of course, to take into account the reviews of specialists who will confirm the reliability of the work performed.

Pros and cons of homemade sectional doors

I would like to note that home-made gates are acquired not only by economical car owners, but also by those who receive moral satisfaction from such work. Many reviews allow us to say that the installation can be done as it is convenient, besides, if you wish, you can add something from yourself.

But do not forget that this is a difficult job. And in some cases, it's better to just buy parts already assembled at the factory, rather than assemble them yourself and worry that the dimensions of the canvas may differ from the existing opening. This way you save time and money.

The negative side of homemade sectional doors is that in this case no one will give guarantees regarding the reliability of the structure. And if the structure is completely or even one canvas falls on the car, then all the blame will lie with the car owner himself.

In order to prevent such a nuisance from happening, you need to use home-made gates only for their intended purpose, strictly following the attached diagrams and instructions. Only this method is effective and will help save money with inexpensive factory parts. These parts must be perfectly aligned with the gate. There are, of course, generic replacement parts, but a thorough check never hurts.

Sectional garage doors for garages are gaining more and more popularity due to their functionality, attractive appearance, relative simplicity of design. In addition, they are very reliable and compatible with various drives to automate their work, although it is also very easy to interact with them manually.

The device of sectional structures

The principle of operation of a sectional sash is very simple. The front sheet, which consists of separate sections, smoothly rises upwards gradually turning and each section, one after the other, is located under the ceiling. The movement occurs due to the rollers, which are mounted on special guides made of aluminum, stainless steel or metal. To facilitate interaction, a system of counterweights from springs is installed. It can be either a simple spring or a torsion bar, which is an order of magnitude better, but also more expensive.

To automate the entrance to your garage, you can use electric drives. Such a device is mounted on the ceiling, and helps to make a smooth lifting at a distance using the control panel. This is especially handy in winter and when it's raining outside.

Do-it-yourself step-by-step instructions

The preparatory process is a very important stage, as it allows you to make further steps and installation of sectional doors smooth and without hitches. In preparation, you carefully plan everything, collect the necessary materials, and also mark the opening for the installation of the future structure.

Preparation will take place on two main points:

Collection of necessary materials, selection of automation and equipment.
According to the selected garage doors, we study the drawings and mark the opening.

We select automation and equipment for the gate

First of all, you need to choose a suitable drive so that it can work without problems with the gate you bought and be fully compatible with them. Also, the selection must be carried out based on financial capabilities, there are different models and they will cost differently.

Pay special attention to the mass of sections and the temperature that can be in the garage in winter, starting from these basic indicators, high-quality automation is selected.

Components must be selected based on your wishes. For example, it is imperative to buy a handle as in the event of a lack of electricity or a breakdown of the automatic drive, it will be very difficult to open the sectional panel. You can additionally install a warning system, latches for blocking sections, locks, structural amplifiers, anti-burglary systems, and more.

Making markup

Marking should be done very carefully. It begins even at the time of the construction of the garage. For sectional doors, you need to leave about twelve centimeters on each side, as well as about ten centimeters from above under the ceiling. Although it is optimal to leave the values \u200b\u200bone and a half to two times more.

Measurements must be taken carefully during installation, because this kind of design should not have even the slightest skew.

Installation must be carried out slowly so as not to make a mistake and subsequently puzzle over how to fix the error without redoing the entire structure again. Constantly measure all sizes, indents, level and parallelism of the guides and then you should not have any problems.

We mount the frame (guides)

This is the main and most time-consuming stage, which takes the most time and requires the greatest effort. This is due to the fact that you must lift heavy rails, hold them and at the same time screw or weld. Immediately take care of an extra pair of hands, the assistant will greatly facilitate the process for you.

The ideal size for the lintel is 25-50 centimeters. If the size is larger or smaller, then the gate must be installed with an appropriate lift.

We start the assembly by fixing the side rails. They are mounted directly to the wall with anchor bolts. Bolts can be screwed both through and with the help of metal plates brought out to the sides. For reliable fixation, at least two anchor bolts are required for each meter of the guide. Check them with a level so that they are strictly vertical.

We simply fasten the semicircular rails with special fasteners to the side rails, and after installing the upper rails, we fasten them to them. For this, simple bolts with several nuts are used.

The top rails are mounted on plates, while they must be strictly parallel and stand at an angle of ninety degrees to the side ones. We fix the plates to the rails on bolts or weld them. They are attached to the ceiling with anchor bolts. To tighten the structure, a jumper is installed between the far ends of the rails, which will prevent them from moving apart.

This is the easiest step as all you have to do is set the blade upright and secure it with a locking rail to keep the rollers from falling out of the rails.

See if the rubber seal is well pressed against the floor. There shouldn't be any cracks!

Making spring balance

This component is necessary in order to raise the garage door with your hands, and in order to lighten the drive force. This design consists of springs, on one edge of which there is a loop, and on the second a threaded pin for adjusting the tension.

We will mount them on the ceiling next to the rails. To begin with, we install fasteners for springs, which consists of a rigid hook to which a special long nut is attached, then we screw the thread of the spring into this nut. We fix the cable on the upper section, and securely fix it on the spring.

When mounting the springs, their axes must be placed strictly on the same level. If this is not done, the uneven load on the springs and bearings will disable them.

After that, we adjust the tension of the spring so that in the closed position it is as tight as possible, but the garage door cannot be lifted.

So that when the gate is opened, the cable does not sag, we install a special coil, which, as it loosens, will wind the cable into a roll. The end result is a garage door that goes up and down very smoothly.

Installing handles

As a rule, it is enough to fasten the handle with bolts, but this happens from the inside to remove it was not possible. You can place it anywhere on the bottom panel, at a distance of at least fifteen centimeters from the floor.

We cover everything

To hide the ugly design of the guides, a plastic casing is mounted on the ceiling, which can be screwed in or closed with latches. The side rails are also covered with plastic panels and acquire an attractive appearance. After that, do-it-yourself garage sectional doors are completely ready and can be actively used.

When buying a sectional garage door, check that all fasteners are included. If you don’t have any, ask to be provided with them, so how to find similar ones that fit exactly and can withstand the entire system is quite difficult, and sometimes even impossible.

Making sectional doors with your own hands, the drawings of which can be freely found, is not a problem. Sectional doors have become widespread since the beginning of the 80s of the last century and at the moment they are the most common. The reason why garage sectional doors are made is quite simple - the reliability of protecting the garage from breaking, rain and wind.

In addition, sectional garage doors are very ergonomic and do not require much space when opening and closing. The main disadvantage that sectional garage doors have is their high price. To reduce the cost, the design is made by hand. Home-made sectional doors (with your own hands) will not be inferior in quality to factory ones, and making them is quite simple. How to make and repair sectional doors with your own hands will be described below.

Option selection and savings

At the moment there are 2 technologies for the manufacture of sectional doors:

Lifting sectional doors, which have a leaf made up of several panels (the number depends on the dimensions of the panel). When they are opened, the canvas folds and tightens up, and when closed, it falls vertically down. At the same time, the panels are made of both metal and wood, durable plastic, etc. Inside, they can be insulated with polystyrene foam or polyurethane foam (foam plastic is too voluminous and will not work, like mineral wool). The scheme of operation of such gates is very common and can be found almost everywhere. It is necessary to connect the panels with the help of hinges, however, they are not weakly resistant to breaking. To make sectional doors composite requires a large budget.
The next option is do-it-yourself sectional doors with a swing-and-lift mechanism. There is a clumsy and non-telescopic shield that must be lifted to open. When lifting with a hinged lever mechanism. Unlike the previous design, this option is perfectly protected from hacking. At the same time, they work almost silently (if the mechanisms are regularly lubricated), which cannot be said about the first option, where the guides and rollers make very loud sounds when moving. The most important advantages of this type of construction are economy and ease of manufacture.

If there are severe financial restrictions, then when implementing the second option, you can save significantly. The most significant savings is the manufacture and installation of all the necessary components yourself with your own hands. You can also save a lot of money by trimming some details.

Most of all, savings will come from refusing the door in the gate, reducing the opening of the gate, installing a manual drive instead of a mechanical one (at the same time, opening the gate will become much more difficult). Also, some amount can be saved by not using decors and designer panels. The dimensions of sectional doors also affect the cost.

The principle of operation of the lifting-rotary shield

Structurally, such gates have 3 elements in their composition: a box, a lifting sash, an opening mechanism. The frame is made of beams (steel or wood). The frame is the main structure, it is installed in the opening. Next, guides are installed along which the entire structure moves during the ascent and descent.

The main difference between this type of gate is that the shield is made of solid material. To do this, you can use wood panels, boards, steel, etc. The best price-quality ratio is available for a wooden shield. It has a low weight, which does not require massive frame structures and a powerful drive of the lifting mechanism. However, the tree quickly becomes unusable under the influence of external factors. But with a competent approach and processing, the life of a wooden shield can be significantly extended. It is best to upholster it with metal. However, no matter what material is chosen for the shield, it is recommended to insulate it.

Manufacturing and installation

In this section, we will consider the question: how to make a garage door? and how to mount the lifting mechanism. In this case, the option of sectional doors will not be considered. This is due to their high cost, low reliability, and besides, the adjustment of sectional doors (composite) is very difficult. It is important to note that installing sectional doors with your own hands (rotary-lever type) is almost impossible - you need an assistant.

The best and simplest option would be a counterweight mechanism. In this case, the cable is attached to the frame (at the lower corners), passed through a fixed block and goes to the winch with a counterweight. The mass of the counterweight depends on the mass of the gate - with the growth of the mass of the gate, the mass of the counterweight increases. This mechanism is simple and easy to use.

Next, you need to draw up detailed drawings for sectional doors, the dimensions are taken in place. After drawing up the project, materials are purchased. This will require: wooden beam 120x80 and 10x10 (for the box and ceiling, respectively), fittings or metal pins, corners 40x40x4 (for rails) and 35x35x04 (for the frame), channel brackets 80x43x5, springs.

A box is assembled from a vertical beam and a transverse one; the connection of the beam must be made with metal corners. The box should be buried in the floor a couple of centimeters (directly into the screed). Next, the bars are attached to the wall with reinforcement.

The next step is to assemble a frame under the shield, which is immediately sheathed with wood and upholstered with metal.

When the shield is ready, it is approximately worth estimating its mass, starting the installation of sectional doors and proceeding to the manufacture of the lifting mechanism. For this, supports are placed from the corners, a channel is attached to the supports, in addition it should be fixed to the racks. Next, holes are drilled for mounting the spring mechanism (three holes are required on one of the bracket shelves).

The hinge angle for the lower part is made from a corner. To do this, a hole of 8-9 mm is drilled and the corner is welded to the frame so that there is an indent from the lower ribs to the middle of the hole in order to freely install the lever for the lifting mechanism. After that, a plate is welded for mounting the spring tension regulator.

During the installation process, it is necessary to carefully control the level of the guides - it should not deviate from the axis. The last stage - a shield is hung on the lifting mechanism. After that, the bottom seal and the side seal are installed, the gate is adjusted in place.

Modern types of garage doors are highly reliable, easy to use, retain heat well in the room and look attractive. It is difficult to make them yourself, but anyone can save on installation and install. To do this, you need to carefully study the instructions and properly prepare the entrance opening.

Gate panels are made of thin steel sheets, between which there is a sealant - polyurethane foam. Insulated panels have excellent thermal insulation properties and practically do not let street noise into the room. In cheap models, a sealant for panels is not used, so they can only be installed in unheated garages.

Installation of mechanisms

A spring break protector is attached to the U-bracket using the same bolts and nuts of the appropriate size.

The end of the cable is inserted into the lower corner bracket, folded in a loop, a wedge is inserted and temporarily fixed with brackets on self-tapping screws. To cock the springs, the manufacturer's instructions indicate the permissible number of revolutions; you need to navigate along the marking strip on the spring itself. The cocked springs are fixed with special knobs, which are removed after tightening the bolts.

Restrictive buffers and shock absorbers are installed last, cables are attached to the drums. To check the balance of the springs and the correct installation of the leaf, the gate is opened halfway and stopped. If the lower edge of the gate is parallel to the floor, the door leaf does not twitch and does not fall arbitrarily, then the installation is done correctly. If the canvas is skewed, jerks and vibrations are felt during movement, the tension of the cables and the operation of the torsion mechanism should be carefully checked.

shock absorber or buffer

At the final stage of installation, handles and locks are fixed on the inside, the tightness of the fit is checked again for smooth running, and if necessary, an electric drive is installed.

Homemade collapsible portal

As soon as the garage is built, the question arises about the safety of the property and it is up to him to decide which gate the owner will use. It is possible to purchase a sectional lifting portal in any specialized market. Specialists can measure the opening, as well as provide assembly, installation and adjustment of garage doors within one week. But the purchased gate will cost quite a lot. Each owner can assemble a sectional lifting garage door with his own hands. It's not a bad idea, but it does come with some difficulty.

You can start such work only if you already have a fairly large experience with similar structures, since the installation and assembly of sections requires a high level of knowledge and skills. It will also take a certain amount of time.

Sash design with solid leaf

The lifting device of a typical garage door construction is able to work on the principle of sectional. To create them, use a solid canvas that will rise to the ceiling. The structure of the sash is complex, and contains a large number of components:

Base box.
Roll cloth.
Guides.
Loops.
Shafts.
Spring systems regulating the balance.
Hangers.
Sealing layer, etc.

support box

The basis for holding the portal is considered static, it is made of an L-shaped profile 65 * 65 millimeters, its length is about 2 meters. Using a drill, you need to make a hole or several for attaching the spring brackets and levers of the lifting device. These holes should not exceed 8-10 millimeters in two radii.

Door leaf

The gate of the garage shield can be made by constructing a frame from an L-shaped profile with an additional reinforcement rib. From the inside, the canvas should be sheathed with a shield of wooden boards, and from the outside with metal sheets. From an L-shaped profile of 35 x 35 millimeters, you can build a frame measuring 2500 x 2100 millimeters.

Mounting the guide for the portal

opening mechanism

To fix the spring mechanism, use brackets made from a channel. To fix springs with a radius inside 15 millimeters, a hole should be made corresponding to those of the rear crossbar. Using a metal plate, it is necessary to regulate the operation of the portal, connecting it with a spring element and brackets. To control, install a weighting agent from a rod (a thread is cut on one side of it, and a ring is welded on the other), on the lower part of the spring.

In the lower part, at a distance of 12 cm above the lower level, a hinge assembly (corner with holes) is welded. The tensioner is attached to a plate with holes welded to the lever.

Special construction guide

The canvas moves to the ceiling due to the fact that special rails are installed from 2 corners of 40 x 40 millimeters and a length of 210 centimeters. They must be fastened using welding, with one edge and leave an interval of 50 millimeters inside between the ends of the corners. The rail should be attached to a plate 80 x 60 x 4 millimeters, in which 4 holes of 6 millimeters are drilled for fastening to the horizontal racks of the box. At the other end of the rail, at a distance of 140 millimeters, a channel is welded, the length of which is 100 millimeters, and the section size is 12x52x6 millimeters. Using a bolt, it should be attached to a horizontal ceiling bar 100 x 100 millimeters in cross section.

Basic structural elements

Types of portal designs

Garage doors can be divided into several types (a schematic representation of the principle of operation of the device below):

Swing open (4).
From sandwich panels (sections, 1).
With lift-and-turn mechanism (2).
Rolled (2).

The typical appearance of a car garage door is a 2-part swing-out portal. The rolled portal consists of 2, 3, 4 or more panels, which, using a system of guides and springs, raise the section under the ceiling when opened. The action of overhead doors is similar to the principle of operation of sectional doors, but instead of several sections, they consist of a single leaf.

A roll-up portal (it is also called a sectional-sandwich-portal) is made of aluminum or plastic panels (lamellas) that are folded into a box above the opening when opened. Installing such a portal at the entrance to the garage is not recommended, due to the large number of shortcomings. They are difficult to make with your own hands (a large number of panels), and are also not a cheap pleasure. Preference should be given to the types of gates listed above.

Varieties of types of structures

Making your own design

If the garage owner decides to make a sectional door on his own, he must consider certain important factors:

Some complex parts that will be needed for assembly cannot be made without special equipment.
Such self-made portals have certain disadvantages: they are quite heavy, cold, and will let the wind into the room.
It is possible to insulate the rolled canvas of the auto garage only with special seals.
If the gate is not insulated, then the lost heat and payment for heating the room will prevail over the benefits received from the manufacture of the portal on their own.

Most craftsmen use polystyrene foam, or mineral wool fiber, to insulate sections, but this practically does not reduce heat loss due to drafts.

Installation of the product in a high room

Due to the high costs of materials and the payment of the turner for the manufacture of guide beams, shaft, web and springs, as well as transportation costs and the cost of painting (in comparison with the production of the structure at a specialized enterprise), you can purchase a ready-made set of garage doors (according to the principle do-it-yourself) and install them yourself.

Preparing to assemble the structure

Assembly of the structure

Installation of the gate is quite simple thanks to very detailed instructions that can be found on the Internet. You can also find drawings and diagrams of garage portals, as well as recommendations for adjusting sectional doors.

The variety of choice of manufacturers of sectional lifting garage doors is quite large, but the most popular portals are also the most expensive.

This is due to the fact that more expensive designs have a web thickness of 45 millimeters, stainless brackets and hinges, overhead handles and bolts, and there is also protection in case the springs break. Also, the tightness of the closing of the sash is at the highest level.

There must be a certain distance between the jumper and the ceiling. If the rise is of a standard size, then more than 210 millimeters, and with a low rise, from 100 to 145 millimeters (depending on the type of control).

What are sectional doors made of?

Standard sectional doors are made up of several metal panels, rails and hangers, a special spring mechanism and an electric drive. The electric drive is not included in the package, it must be purchased separately, while the gate can be controlled in manual mode.

Gate panels are made of thin steel sheets, between which there is a sealant - polyurethane foam. Insulated panels have excellent heat-insulating properties and practically do not let street noise into the room. In cheap models, a sealant for panels is not used, so they can only be installed in unheated garages.

Sectional garage door design

Steel profiles equipped with brackets are used as guides. They are fixed along the perimeter of the opening and on the ceiling, where they are held by a special suspension. The spring mechanism provides easy sliding and balancing of a cloth. Additionally, the product is equipped with fasteners.

The outer coating can have a decorative pattern, a textured or smooth surface, an imitation of a natural texture. Some models have an acrylic window built into the panel, resistant to impact and damage, but well letting in sunlight.

The outer coating can have a decorative pattern, a textured or smooth surface, an imitation of a natural texture.

How to prepare an opening for installation

The installation of such gates requires the exact implementation of the instructions, because the slightest flaws can lead to a distortion of the structure, difficulty in sliding the canvas and serious damage. The dimensions of the sectional doors must correspond to the parameters of the opening, the opening itself must be properly strengthened and prepared in order to eliminate all possible shortcomings.

For preparatory work and installation of the structure, you will need:

building level;
drill;
roulette;
a hammer;
set of drills;
pliers and wrenches;
trowel;
cement-sand mortar.

Step 1. Finishing

After installing the gate, it is more difficult to make the outer lining of the opening, so it is recommended that the exterior finishing work be done in advance. To do this, remove the worn-out finish, cover the gaps with a solution, level the inside of the opening and the adjacent sections of the walls.

Step 2. Strengthening the opening and installing the frame

For a garage made of light silicate or foam blocks, additional reinforcement of the opening will be required. They take metal corners 100x100 or channel No. 10, cook a frame from them according to the size of the opening and install it with anchor bolts. A concrete, brick and metal garage does not need such reinforcement.

After installing the frame, its surface is ground with a grinder, primed, plastered joints with the wall, painted. Preparation of internal surfaces is carried out more carefully: any unevenness of the wall adjacent to the opening reduces the tightness of the joints of the gate and contributes to the loosening of the structure.

According to the installation technology, there should be a free distance of 45 cm on both sides of the opening on the inside. If the width of the walls is less, it will not work to install the sectional door correctly. The minimum height of the lintel is 25 cm, for some models - 30 cm.

An important point: if communications are fixed above the opening, and it is not possible to move them, the height of the lintel is measured from the upper edge of the opening to the lower point of the communication connections.

These areas must be leveled with putty, sanded and treated with a primer mixture. Next, the horizontalness of the floor is checked: a long, even rail is laid on the floor in front of the opening and the number and depth of the gaps are determined. If the horizontal error is only 1-2 mm, alignment is not required, in other cases, a screed is required. The room must be freed from large objects, a set of gates laid out on the floor, a stepladder prepared and installation proceeded.

Step-by-step gate installation technology

Scheme of installation of garage sectional doors

Step 1. Markup

Begin the installation process with markings for mounting rails. They take one panel, put it horizontally across the opening, so that the edges of the panel evenly go onto the walls on both sides. Stepping back from the panel 3 cm to the side, a mark is made on the surface of the wall with a pencil. On the other side of the opening, everyone does the same. Then the panel is removed, a level is taken and a vertical line is drawn from floor to ceiling through the mark. Permissible vertical deviations are 2 mm, with a larger value, the skew of the guides will negatively affect the movement of the web.

Step 2. Attaching the frame to the wall

Holes with a diameter of 12 mm are drilled along the marking lines in several places, dowels of the appropriate size are driven in and guide racks are baited. You can tighten the fasteners tightly after vertical alignment. Horizontal rails are attached to the vertical rails and fixed with a retaining bar. At the joints, the resulting gate frame is reinforced with bolted connecting plates.

Having installed and fixed the frame on the walls, carefully check the fit areas for gaps. If there are gaps between the profile and the wall, you need to put thin metal plates under the guides for alignment. It is undesirable to use other materials, because under the weight of the gate they can be deformed.

Step 3. Assembling the canvas

Corner brackets are installed on the bottom panel; Each bracket is fixed with 4 self-tapping screws. On the upper edge of the panel there are holes for fastening the hinges: the hinges are applied to the panel, aligned and screwed with two self-tapping screws. Next, they put the hinges on the middle and top panels, attach the side supports and rollers to move the web along the profile. Insert the lower and middle sections into the guides, connect them with hinges, then attach the top panel.

The finished canvas should fit snugly against the opening around the entire perimeter. At this stage, you can begin to install the mechanisms.

Installation of mechanisms

U-shaped support brackets are attached to the upper and lower ends of the vertical racks; on the lintel, a torsion mechanism is installed in these brackets: on the right they put a spring with a twist counterclockwise, on the left side - vice versa. The springs are fastened with a coupling and additionally fixed with an internal bracket. On the sides, the torsion mechanism is tightened with M10x25 mm bolts.

High-quality installation will ensure uninterrupted operation of sectional doors for 8-10 years; the only thing that will have to be periodically adjusted is the springs, which gradually stretch under the weight of the structure. But it will not be difficult to fix minor problems or adjust the mechanisms after self-installation of such gates.

Do-it-yourself sectional doors

The main generally accepted qualities for garage doors are reliability, practicality and ease of operation. The design of sectional doors has all the listed qualities, while they do not require additional space when opening and they can be easily made lifting-automatic.

Do-it-yourself sectional doors

Thanks to modern materials, they have good thermal insulation properties and can perfectly transform the facade of the garage.

The main disadvantage of sectional garage doors is their price. Compared to conventional swing gates, it can be more than two times or more.

There are a fairly large number of companies on the market that manufacture, sell and install such gates. But the presence of great competition in the market still did not affect the price. The reason for this is the complex structure of the gate and design.

In order to somehow save on installation, we advise you to buy a ready-made mechanism and do the installation yourself, as well as choose the factory colors of the gate, they are no worse than the author's ones and are durable.

The design of sectional garage doors consists of slats fastened together in a single leaf, and a mechanism consisting of guides, spring blocks to balance the leaf during movement, and a lifting-torsion system that ensures the movement of the leaf along the guides due to a system of cables, shafts and drums .

Description of sectional doors

The guides, which are assembled into a single structure, are attached to the wall of the opening from the inside of the garage and the ceiling. Due to the lifting-torsion system and spring blocks, the gate can walk along the rails.

Sectional garage doors

When opening the garage, the gates are hidden under the ceiling due to the lifting force of the electric drive or hands, and when closed, they are smoothly locked.

Conditions to be met before installation

The opening of the garage must be reinforced with a metal frame. It can be a channel or a frame welded from a corner and metal plates.

The distance from the side of the opening to the wall must be at least 250 mm, on the other side it must be exactly the same. From the upper edge of the opening to the ceiling, the distance must be at least 350 mm.

Sectional door installation material

We recommend that you do not try to make mechanisms and canvas for garage doors on your own. It will take a lot of time and it is unlikely that you will be able to do it well and reliably. The reason for this may be the lack of modern materials and branded components.

The best option would be to order a standard set of gates according to the size of the opening and assemble them yourself according to the available instructions.

The slats are a sandwich panel, which consists of galvanized steel, painted on the outside with a polymeric decorative paint. A layer of insulation is laid between the panels.

For unheated garages, you can choose lamellas with a thickness of 20 mm; for a heated garage, it is recommended to take lamellas with a thickness of 35 mm or more.

Various types of panels allow you to choose according to your needs

With ready-made parts, adjusted to the required opening dimensions, the installation of the gate will not take much time. It is advisable to have an assistant during installation and adjustment of mechanisms.

Necessary tools for work:

For marking you will need a level and a tape measure.
Pliers and screwdrivers for mounting.
Screwdriver and drill for attaching rails to the opening wall and garage ceiling.
Bulgarian in case of cutting material.

Gate installation

After receiving a complete set of garage doors and strengthening the opening, you can begin to mark the fasteners according to the attached diagram. Start by marking the walls and ceiling, indicate the places where the guides will be attached.

If the ceiling height is higher than the required size indicated in the diagram, you need to take care of longer fasteners or provide linings for stable fastening.

The main supporting frame, to which the remaining elements will be attached, is assembled in a certain order indicated in the diagram. The next step is the assembly of the garage door leaf.

The canvas must begin to be assembled from the bottom lamella. At the end, it is necessary to adjust the sash so that its upper part is tightly closed with a flashing. This is ensured by adjusting the brackets located at the top of the structure.

It is better to check the gate movement beforehand. They should walk along the guides smoothly and not get stuck.

When the leaf is assembled and adjusted, it is possible to finally fix the gate nodes, install spring blocks, an automatic control system. The spring blocks are adjusted so that the cables of the lifting torsion system are always taut.

Spring blocks for sectional doors

The final touch in the installation should be the installation of a sensor to limit the movement of the leaf. After the gate is tested for smooth running, the automatic opening and closing system is checked.

What should be taken into account during installation?

The design should be assembled with the highest quality possible, there should be no gaps between the parts, all fasteners should be tightened as tightly as possible.
The guides are set as evenly as possible, all corners must be maintained, otherwise the sash may jam.
Fixing the gate at a certain height is only allowed when using metal spacers.

Maintenance

Despite the fact that the installation of garage sectional doors is quite complicated, during installation, if the necessary assembly order and requirements are followed, the structure will last for a long period and will not fail for many months.

This is mainly due to the high reliability of the components and compliance with the specified operational period. But breakdowns happen not only due to poor-quality installation or bad parts, but also due to negligence or negligence of the owner.

The most common breakdowns relate to mechanical damage to the sash, failure of an element of the lifting and torsion system, wear of the rollers of spring blocks, short circuit or wear of the automation system.

All these breakdowns are quite easy to fix by replacing the failed parts. The main thing is to foresee such situations in advance and stick a sticker on the inside of the gate with information about the gate model and details of the company from which the gate was purchased.

The complex structure of the structure and a large number of elements require periodic inspection and careful handling by the owner.

Sectional doors are very popular in European countries. And recently the demand for them is increasing in our country. They are installed in a variety of places: in offices, industrial enterprises and, of course, in private homes. Most often, sectional doors are installed on garages. Why are they so loved by consumers? To get an answer to the question, you need to understand what the gates are, as well as know their pros and cons.

Design features of the gate

By design, sectional doors are quite simple. Several sandwich panels, fastened with loops, make up an integral canvas. This canvas moves with the help of rollers along horizontal and vertical guides fixed on the canvas and the inner wall, respectively. When opening the gate, the sections move one by one along the rails into the space under the ceiling.

For each gate individually selected torsion springs depending on the weight of the structure. This makes it easy to raise and lower the sectional door manually. But if the gate is large enough (more than 9 square meters), it is recommended to install electrical or mechanical drive unit. In this case, they can be opened using the remote control or the fixed switch key.

Sectional doors are enough durable. Their device is protected from cable breaks by ratchet clutches. Such protection blocks the canvas of impressive weight, preventing it from falling. And in the event of a power outage, electric gates can be unlocked and open with a special key.

The structure of sectional doors is quite complex. In the design, some manufacturers provide for the placement of the entrance gate. Although here each manufacturer has its own size restrictions for arranging a small additional entrance.

Pros and more pros

Installing a sectional door gives users a number of essential benefits:

But sectional doors have their own limitations. Chief among them is enough high price. But this is due to the use of high-quality materials in their manufacture, which provide many positive characteristics.

Materials for the manufacture of sectional doors

For the manufacture of sectional doors, sandwich panels are used, consisting of a pair of sheets galvanized iron with insulation in the middle. Various materials can be used as insulation, for example, polyurethane foam or polyester. The panels themselves are made only in industrial conditions. In the same place (in production), a decorative coating is applied to them.

In order for the gate to have sufficient thermal insulation, manufacturers get rid of “cold bridges” during the manufacturing process. Achieve this by installing between sections elastic stoppers that fit snugly against the panels. A special frost-resistant sealant is attached to the lower part of the gate (threshold panel), which prevents the doors from freezing to the floor during the cold season.

What is the cost of sectional doors?

Such gates are quite popular today, and the competition in the market is great. After analyzing the offers, it can be noted that a standard sectional garage door can be purchased for about 40-45 thousand rubles. Although there is a cost and 10 times higher, but this is far from the standard.

Such a difference in price is due to various variations of the door finish. A typical standard size variant covered in basic paint shades is usually the cheapest. If gates of unusual colors are needed, then this will lead to rise in price by 15−20%. Finishing with precious woods or forging will lead to a more serious increase in the cost of products.

Should I take on the job myself?

The desire to save money or love for complex technical problems push consumers to develop and install homemade sectional doors. But the implementation of such an idea can lead to negative consequences, such as:

unforeseen increase in costs in progress;
design unreliability with an indefinite period of operation;
frequent breakdowns gate, etc.

An alternative option in this case could be the so-called constructor. That is, the manufacturer offers to buy accessories for assembling the gate with the attached original drawings. Here main correctly read the diagram and correctly apply to the doorway.

Making sectional doors with your own hands: an algorithm

The gate can be made independently if you have free time and skills in the field of construction. But here you need to clearly understand that such work is painstaking and rather complicated. If the desire is not lost, then action algorithm is:

Secrets of successful installation of sectional doors

In order for the gate to be strong and reliable, certain points must be taken into account during the installation process. For example, additional space is still needed. It should be from the inside around the doorway: on the sides - up to 45 cm, to the ceiling - about 30 cm.

You need to start the installation with the preparation of the doorway. Be sure to remove the fragile facing layer (if any). In case the gate is installed in a garage made of lightweight blocks, must be strengthened metal frame walls.

The main conditions for high-quality installation of sectional doors - precisely set opening vertical(without the slightest distortion) and tightly fixed among themselves structural details. It is unacceptable to use mounting foam and wooden pegs during the installation of load-bearing elements.

Compliance with these rules will guarantee quality installation. And remember, if you are not confident in your abilities, maybe you should think about buying a ready-made version of the gate.

Modern types of garage doors are highly reliable, easy to use, retain heat well in the room and look attractive. It is difficult to make them yourself, but anyone can save on installation and install garage sectional doors with their own hands. To do this, you need to carefully study the instructions and properly prepare the entrance opening.

Some models have an acrylic window built into the panel, resistant to impact and damage, but well letting in sunlight.

How to prepare an opening for installation

The installation of such gates requires the exact implementation of the instructions, because the slightest flaws can lead to a distortion of the structure, difficulty in sliding the canvas and serious damage. The dimensions of the sectional doors must correspond to the parameters of the opening, the opening itself must be properly strengthened and prepared in order to eliminate all possible shortcomings.

For preparatory work and installation of the structure, you will need:

building level;
drill;
roulette;
a hammer;
set of drills;
pliers and wrenches;
trowel;
cement-sand mortar.

Step 1. Finishing

Step 2. Strengthening the opening and installing the frame

An important point: if communications are fixed above the opening, and it is not possible to move them, the height of the lintel is measured from the upper edge of the opening to the lower point of the communication connections.

Step-by-step gate installation technology

Step 1. Markup

Step 2. Attaching the frame to the wall

Step 3. Assembling the canvas

The finished canvas should fit snugly against the opening around the entire perimeter. At this stage, you can begin to install the mechanisms.

Installation of mechanisms

U-shaped support brackets are attached to the upper and lower ends of the vertical racks; on the lintel, these brackets are installed torsion mechanism: on the right they put a spring with a twist counterclockwise, on the left side - vice versa. The springs are fastened with a coupling and additionally fixed with an internal bracket. On the sides, the torsion mechanism is tightened with M10x25 mm bolts.
Attached to the U-shaped bracket spring break safety device using the same bolts and nuts of the correct size.
The end of the cable is inserted into the lower corner bracket, folded in a loop, a wedge is inserted and temporarily fixed with brackets on self-tapping screws. To cock the springs, the manufacturer's instructions indicate the permissible number of revolutions; you need to navigate along the marking strip on the spring itself. The cocked springs are fixed with special knobs which are removed after tightening the bolts.
Installed last restrictive buffers and shock absorbers, cables are attached to the drums. To check the balance of the springs and the correct installation of the leaf, the gate is opened halfway and stopped. If the lower edge of the gate is parallel to the floor, the door leaf does not twitch and does not fall arbitrarily, then the installation is done correctly. If the canvas is skewed, jerks and vibrations are felt during movement, the tension of the cables and the operation of the torsion mechanism should be carefully checked.
At the final stage of installation, handles and locks are fixed on the inside, the tightness of the fit is checked again for smooth running, and if necessary, an electric drive is installed.
