• frame. If it is executed from profile pipe 40x20 mm with a wall width of 2 mm, weight 1 linear. m will be 1.7 kg. The perimeter of 2 gate leaves with a width of 3 m and a height of 2 m will be 12 m. Additionally, the leaves are reinforced with transverse beams (another 1.5 m for each). Thus, the total length of the profile pipe is 15 m, and the weight is 25.5 kg;
• filling the valves. If 1.5 mm thick sheet steel is used for filling, its weight will be about 70 kg.

Thus, the total weight of metal swing doors will be about 95.5 kg. It is also necessary to add the weight of locking fittings, decorative elements, etc.

The design of support pillars, as well as the choice of hinges for swing gates and the method of their installation, is determined in strict accordance with the weight of the leaves.

Metal swing gate design

The main structural elements for are:

• support pillars;
• doors

Support posts for metal swing gates can be made of metal or brick. Metal pillars are made from a profile pipe, the cross-section and wall thickness of which is at least not less than that of the profile pipe for the sashes. During installation, the pillars must be concreted. Master Company engineers recommend that the foundation goes below the freezing depth. The pillars are installed (or laid out) strictly vertically. A building level is used for control. This is necessary in order to avoid distortions of the sashes.

The design of the sashes must have a frame frame. Additionally, it is reinforced with diagonal or horizontal beams.

Requirements for materials and accessories

• The materials of the sashes, frames, support posts, as well as hinges, spring elements and locking mechanisms are selected taking into account operational and wind loads. The combination of materials and components must take into account the total weight of the sashes and ensure strength, rigidity and stability of the geometric parameters of the structure.
• Metal structural elements must be protected from corrosion.
• If applied to metal polymer coating, before this it must be covered with soil.
• The thickness of the polymer coating must be more than 30 microns.
• If the metal is painted paint and varnish materials, the coating must comply with GOST 9.401.
• Glazing of the sashes can be done using multi-layer or tempered glass, made from polymer materials glass or double glazing.
• Fittings and locking elements are selected in accordance with the weight and size characteristics of the structure. They must be protected from corrosion.

The dimensions of the security gates directly affect the safety and ease of use of the garage. Typically, calculation work is carried out by specialists from the company from which you plan to purchase the structure. But you can do this work yourself, thereby saving time and money spent on construction.

Optimal garage door sizes

When designing and constructing a garage, SNiP 2.07.01–89 is used, which determines the layout and construction technology of buildings located in populated areas. The document clearly states the parameters land plots for the construction of a garage and rules fire safety in these buildings.

The rules and requirements for the manufacture of garage doors are specified in GOST No. 31174–2003. It details the classification of garage doors, General requirements to the design, characteristics and recommendations for its installation.

The calculations and parameters of garage doors are not specified in GOST, therefore, when designing the structure, you should focus on the dimensions of the car and general dimensions premises.

When calculating garage opening Please note that the height must be 21 cm greater than the existing vehicle

Conventionally, the following rules can be distinguished when designing garage doors:

• height - must be 21 cm greater than the height of the existing car. If a vehicle is to be replaced, then the nominal height is taken to be the maximum size of the vehicle in the class that is planned for purchase;
• width - when driving on a flat surface, it should be 0.8 m greater than the width of the existing vehicle. If the entrance to the garage is located below the garage level, then the width increases to 1 m.

When designing a garage for two cars, the formula is used: L = (L1 + L2) + 0.5 + 0.7, where L is the width of the garage door, L1 and L2 are the width of the first and second car, the value of 0.5 determines the safe distance between cars at the moment of simultaneous movement in meters, and the term 0.7 is the sum of the distances between the edge of the car and the boundaries of the opening in meters.

Up-and-over garage doors are a structure consisting of a single protective leaf, a locking device, lifting mechanism and horizontal guides.

When opening, the lower part of the protective gate leaf moves forward, and the upper part gradually rises to the ceiling due to fixation to the guides. As a result, part of the canvas goes under the ceiling and is located almost parallel to the floor in the garage. The remaining part extends beyond the garage.

When open, up and over gates reduce the opening height by 20–25 cm

With fully open lifting swing gates ah, the height of the opening is reduced by 20–25 cm, depending on their design. Therefore, this value must be taken into account in calculations.

As an example, let's calculate the dimensions of a swing gate for a C-class car with a width of 1.7 m and a height of 1.5 m:

• height - calculated using the formula H ≥ (1.5 + 0.4) + 0.25 + 0.2 = 2.35 m. In this case, we made an allowance of 0.4 m, since it can be installed on the roof of the car trunk. If one is not installed, then this surcharge can be removed;
• width - calculated by the formula L ≥ 1.7 + 0.8 = 2.5 m. With an entrance located at an angle, the width of the gate increases to 2.7 m.

Taking these parameters into account, you can proceed to the selection finished design gates or components for self-production. When calculating the door parameters for a two-car garage, the calculation logic remains the same.

For example, one car will have the parameters described above, and the second will have a width of 1.8 m and a height of 1.7 m. In this case, when calculating the height, only the largest value is taken: H ≥ (1.7 + 0.4) + 0.25 + 0.2 = 2.55 m. The width of the gate for two cars is: L ≥ 1.7 + 1.8 + 0.5 + 0.8 = 4.8 m.

Lifting sectional doors consist of a composite protective sheet, vertical and horizontal guides, a lifting and locking mechanism. The composite fabric consists of several rectangular elements connected to each other using hinges.

Sectional overhead doors practically do not reduce the height of the opening

When the gate is opened, the door leaf begins to rise due to automation, gradually being pulled up to the ceiling. The presence of loops allows the canvas to bend, which allows it to move under the influence of traction. In contrast to the swing design, sectional doors when raised reduce the height of the opening slightly - up to 5 cm, depending on the manufacturer.

The formula for calculating the height for overhead sectional doors will be as follows: H ≥ (H1 + 0.2) + 0.1, where H1 is the height of the vehicle, 0.2 is the distance from the car roof to the opening in meters, 0.1 - the distance required for the free position of the protective flap under the ceiling in meters.

Taking into account the size of the car from the previous example, the sectional door will have the following parameters:

• height - H ≥ (1.5 + 0.4) + 0.2 + 0.1 = 2.2 m. If you do not plan to install a rack on the roof of the car for transporting oversized cargo, then instead of 0.4, substitute 0 into the formula, 2;
• width - L ≥ 1.7 + 0.8 = 2.5 m. The width is the same as in the case of swing gates, since the main difference between the designs is only in the method of opening the gate and installing a protective leaf.

When calculating the height of a garage door for two cars, the height of the largest car is taken as the calculated value. The width, as in the previous case, is calculated by the formula: L ≥ (L1 + L2) + 0.8 + 0.5.

Roller gates

The design of roller doors has much in common with sectional doors. The protective fabric consists of many lamellas, which, when the gate is opened, are wound onto a drum located above the opening.

When opening, roller gates are screwed onto a drum at the top of the structure

The drum itself with the mounting box can be located both indoors and in the opening or outside the garage. Horizontal guides are not used in rolling shutters.

The calculation of the dimensions of roller shutters is almost completely identical to the sectional design. The following formulas are used for calculations:

• height - H ≥ H1 + 0.2;
• width - L ≥ L1 + 0.8.

Folding gate

Garage Doors with folding protective flap consist of several vertical panels connected to each other hinged hinges. When opening, the gate leaves move along a horizontal guide fixed in the upper or lower part of the opening.

Folding gates reduce the width of the opening by the thickness of the folded sections

According to the method of opening, folding gates are divided into single and double. A single leaf folds in only one direction - left or right. The double sash splits in the middle and folds in both directions at once.

When folded, the gate sections reduce the width of the opening. For garage doors used in the private sector, this value is no more than 30 cm, for industrial structures - 50 cm or more.

Taking this into account, the calculation formulas for folding gates will look like this:

• height - H ≥ H1 + 0.2;
• width - L ≥ L1 + 0.8 + 0.3.

If you make it yourself, the extra width can be calculated more accurately. To do this, you need to know the thickness of the material that will be used to make the protective sections. After this, the approximate number of sections is calculated.

As a result, the width of one section is multiplied by their number - this approach is used when calculating large-width gates, when the protective leaf will be made using heat-insulating materials.

Swing gates

The design of swing gates is the simplest. The gate is divided into two leaves, which open outward to the left and right. One of the doors has a door or gate for entering the garage without opening the massive door.

Swing gates do not change the size of the garage opening

When calculating gate parameters, standard allowances for width and height are used. The safe width of the gate should be 70–80 cm greater than the width of the vehicle, and the height of the gate opening should be 20 cm greater than the height of the vehicle. The vehicle parameters are taken from the technical passport.

For garages for two cars, it is better to provide two working openings with swing gates. This is due to the fact that the heavy structure of the protective sash will load the fastening and turning elements. As a result, the fastening points will sag, and the geometry of the gate will be disrupted.

Calculation of door parameters for trucks

Calculation of garage door sizes for heavy vehicles and trucks is carried out using similar formulas using their additional values. The calculated data is based on the width and height of the vehicle that is planned to be parked in the garage.

Dimensions of a truck with an open body

Further, additional values ​​recommended for cars of this class are added to these parameters. They are listed in the table. Minimum space between by freight transport at the time of simultaneous departure should be at least 0.7 m.

Table: additional values ​​for the length and width of the garage opening for trucks

An example of calculating an opening for installing swing gates

As an example, let's calculate the parameters of a swing gate for a car 2.4 m high and 2 m wide:

• height - H ≥ 2.4 + 0.2 = 2.6 m;
• width - L ≥ 2 + 1 = 3 m.

If it is planned to install a closed tarpaulin or metal body on a truck, then the estimated height is measured relative to highest point on the body. A similar approach is used for minibuses and family cars.

Calculation of the parameters of the opening and gate must be carried out at the garage design stage. This will allow us to provide technical features gates and will help calculate the optimal parameters for structures different types. After the garage is built, the opening will take on a finished appearance and it will not be advisable to expand it further, as this will lead to a weakening of the supporting structure.

The garden plots of private houses are fenced with a fence, in which, regardless of the type, a gate for the passage of people and a gate for a car must be installed. Most often, swing structures are used for these purposes, less often – sliding structures.

Metal is usually used as a material for gates, since metal ones, unlike wooden ones, will last longer.

What should the gate be like?

When making your own gates or purchasing ready-made gates, you must take into account the basic requirements that they must meet. The gate must be:

1. durable and rigid, as well as resistant to burglary and entry into the territory;
2. moderately heavy - their weight should withstand gusts of wind, and at the same time time easy so that they can be easily opened and closed;
3. aesthetic and individual - swing gates can be made more beautiful and elegant than standard and monotonous metal sliding or sectional ones.

GOST No. 31174-2003 regulates all the requirements for metal gates, and also describes all their main types. In addition to swing and sliding structures, there are 9 more options - these are sectional, folding, etc. However, all these fencing systems are not often used, since their installation is accompanied by some difficulties: installing a technological arch or a niche for the canvas.

Video: Metal gates and gates for the garage.

Norms and technical conditions

The requirements for swing gates are defined in GOST 31174-2003, which stipulates general provisions, but specific characteristics are determined directly during design. To reliably lock and block the opening, the gates must be installed on massive pillars and have a strong frame.

The strength of the frame is ensured by the presence of a large number metal elements, which entails an increase in the mass of the structure. And this in turn increases the load on the frame and hinges of the system. Therefore, in order to avoid breaking of hinges, as well as sagging of sashes and other emergency situations, the GOST stipulates the condition - mechanisms and components for swing doors metal structures must be manufactured strictly according to project documentation and manufacturer's calculations:

• hinges and canopies, as well as the frame and frame must have a double margin of safety, and the quality technical solutions, must be confirmed by certificates of conformity from the standardization center and a sanitary and hygienic conclusion of the State Sanitary and Epidemiological Supervision;
• metal swing gates should not have metal surface defects visible to the naked eye;
• welds must meet strength and continuity standards;
• the difference in height and width of the racks should not be more than 5 mm;
• permissible diagonal deviation of metal sashes up to 2 m – 3 mm, for sashes over 2 meters – 5 mm;
• The paint coating layer must be at least 30 microns and must not cause allergic reactions upon contact with skin.

The resistance of the structure to shock loads is checked by dropping the assembled sashes onto a hard surface. After all the tests have been carried out, the manufacturer draws up a technical passport of the product and applies markings indicating: model VM (metal gate), GOST number and dimensions.

Dimensions and weight

The height of swing gates used in the private sector usually does not exceed 3 meters, for industrial structures - 5.5. As the height increases, the mass of the doors and their windage increases, which leads to difficulties in operation.

The width for each case is calculated individually. The main criteria for calculation include:

1. availability of free space;
2. the width of the vehicle that will pass through them: take the maximum width of the car and add a margin so that it can pass freely, for private houses 3 m is enough - the width of a passenger car does not exceed 2 m and 50 cm on each side for free passage.

Making gates large sizes without urgent need it is not always practical: firstly - big square will lead to increased wind load, and secondly, the structure will be heavy, so additional reinforcement will be required.

The weight of metal swing gates depends on what material was used for their production. An approximate calculation is done like this:

• The frame is a profile pipe 40 × 20 mm with a wall width of 2 mm. The weight of 1 m of profile pipe is 1.7 kg. For a gate with a width of 3 m and a height of 2 m from 2 leaves, the perimeter will be 12 m. Each leaf is reinforced with transverse beams - 1.5 m for each. It turns out that you need 15 meters of profile pipe, the total weight of which will be 25.5 kg;
• Sheathing – sheet steel. The thickness of the metal sheet is 1.5 mm, the total weight will be within 70 kg.

It turns out that the weight of metal swing gates will be about 95.5 kg. Add to it the weight of the locking hardware, decorative elements And so on.

Advantages and disadvantages

Swing gates are both excellent protection of the territory from penetration and a simple and convenient design. They have a number of advantages, namely:

• in production you can use modern metal profiles, and this in turn gives scope for bringing design ideas to life;
• Most metal elements are coated with a special polymer coating, which protects against corrosion, temperature changes, etc.;
• no on metal swing gates visible elements fastenings, so they are more difficult to break;
• the design can be made according to individual project, using elements artistic forging, automatic opening and much more.

But, just like any other gate structures, swing gates also have disadvantages. Since the sashes are quite heavy, they may become skewed and lowered. This problem is solved by installing more powerful supports made of brick, reinforced concrete or steel.

If the gate leaves are wide and therefore heavy, it is more difficult to avoid their sagging, as well as wear and bending of the hinges. As the area increases, the windage and, accordingly, the wind load will increase.

Swing gate designs

There are several types swing structures, each of which performs its own certain functions and also reflects modern look at the gate. Among the most popular are:

1. forged - protective decorative functions;
2. aluminum – lightness and speed;
3. made of corrugated sheets - reliable and comfortable.

Forged swing gates

They serve not only to protect the passage, but also decorate the territory of a private home. All doors can be forged completely, from the frame to the lintels and small parts- the most expensive, but beautiful models. For cheaper options, the main elements, such as the frame of the doors and lintels, are made of pipes, and artistic forging parts are used as decoration.

The doors of forged structures are most often suspended on hinges from mortgages in brick pillars. The upper part of the doors can be either completely open or with decorative polycarbonate inserts. The lower part is usually covered with metal cladding.

Aluminum

Aluminum structures are used with automatic drives in service parking lots and company areas. They look modern and businesslike. The doors close quickly, easily and almost silently.

The sashes are made of aluminum profile 96 × 177 mm or sandwich panels, protected from deformation by an internal diagonal cable stretch. The manufacturer guarantees 25 - 28 thousand operations, and no corrosion for 15 years.

From profiled sheet

The design of metal pipes covered with profile sheets is considered the most popular, modern and practical. Such doors are practically not inferior in strength to forged gates, and the ability to make the structure yourself only increases their popularity.

In the manufacture of this option, the same technology is used as in the production of a fence from corrugated sheets. The cladding can be easily matched to the color of the fence. The weight of doors with a height of 3 meters will be about 300 kg. And the cost is much less than aluminum and forged options.

Approximate prices to the above structures:

When choosing a gate for your site, experts recommend being guided by the following principle: if the fence is made of metal profiles or modular sections, for it the best option There will be swing gates made of aluminum or a steel profile, and for a fence made of stone, a forged option will be an excellent choice.

How much do gates weigh?

Very often the customer is interested in the question of the relationship between the size of the gate leaf and the post on which it is attached. Let's try to understand this issue using the example of a gate made of corrugated sheets.

Frame material

The frame of the gate leaf is made of profile metal pipe cross-section 40×20 or 40×25 with a wall thickness of one and a half to two millimeters. Let's calculate the mass of the frame for the sash. To do this, you need to know the weight of one meter of the profile pipe from which the fabric of the future design will be made. So, 1 meter of 40x20x1.5 pipe weighs 1.4 kilograms, and one meter of 40x20x2 pipe weighs 1.7 kg. For ease of calculation, we provide examples of common gate designs.

Sketches for calculating length and weight

Sheathing material

The material for the cladding in our case will be corrugated sheeting for fences marked C20 with a thickness of 0.5 mm. Square meter This material has a mass of about 5 kilograms. For swing gates 4 meters wide (the most popular size is from 3 to 4 m) with a fence height of 2 meters, 4 sheets are needed, two for each leaf, i.e. it turns out to be a maximum of 20 kilograms.

So, the weight of one gate leaf is about 40 kg. This weight can be supported average person. The weld seam with which the gate is attached via a hinge to the post is capable of withstanding a load much greater than that created by the specified mass. Therefore, two loops for each half are quite enough.

Metal swing gates: GOST, weight, dimensions

A fence of any type and design should always have a wicket and entrance gates, most often swing or sliding, allowing passage of a car or even a truck into the site. Today, metal swing gates are most often used for private properties. Less often - light recoil ones. The larger the fenced area, the taller and more serious the building, the more monumental the fence, the higher the gate, more metal used to make frames and supports that ensure stability and strength of the structure. It is not surprising that instead of cast iron and welded profiles, modern swing gate structures are increasingly using aluminum and forged rods.

Which gate is better

Today the manufacturer strives to make gates for private properties:

• Maximum strength and rigidity, ensuring the resistance of the protective fence to breaking and entering into private territory;
• Heavy enough so that the weight of the gate and inertia make it possible to withstand wind breakthroughs, and at the same time light so that the installation and operation of swing metal gates does not require the use of huge massive pillars and supports;
• Beautiful and graceful. Old as the world, swing gates can look hundreds of times more attractive than the monotonous and boring design of metal sliding, lifting or sectional entrances.

For your information! A system of two sashes on vertical hinges has one important advantage - the rotary unit on the canopies has twice the service life and reliability of the mechanism than similar “flat” structures. The standard service life, determined by GOST for all types of swing metal gates, is 20 thousand opening and closing cycles.

In reality, for high-quality metal swing gates these values ​​can easily be exceeded by 50-70%.

GOST No. 31174-2003 summarizes and describes all the main types of metal gates. In addition to swing and sliding systems, nine more options can be used to “lock” the passage, from sectional to folding. But in structures for fencing areas, such devices are used quite rarely, since their use requires the installation of special technological arches and niches for cleaning the door leaf or panels. In rare cases, roller shutter systems can be used to lock and block the passage, but in this case, installation will require converting the open base of the gate into a closed structure with the installation of a technological arch or transverse beam above the passage.

To open the heaviest metal systems with swing doors without the use of an electromechanical drive, the effort of just one person is sufficient, while opening or moving sliding structures without the use of a standard electric drive is much more difficult.

Standards and technical specifications for swing metal systems

To ensure reliable locking and blocking of passage, metal swing gates have to be installed with a massive frame or pillars, and most importantly - with big amount steel load-bearing elements ensuring the strength of the main frame. This leads to an increased weight of metal swing gates and a huge load on the frame and hinges, first of all.

To avoid breakage of the suspension, sagging of the sashes or emergency situation in case of strong gusts of wind, GOST establishes the requirement that all mechanisms and components of swing metal structures must be manufactured only according to design documentation and strength calculations of the manufacturer:

Hinges, awnings, internal frame, the frame of swinging metal gates must provide the necessary double margin of safety, while the quality of the technical solutions incorporated in the design must be confirmed by certificates of conformity from the standardization center and a sanitary and hygienic conclusion of the State Sanitary and Epidemiological Supervision Authority for the product;

The quality of manufacture of metal swing gates is checked for the absence of metal surface defects visible to the naked eye, and compliance of welds with strength and continuity standards. The difference in the height or width of gates of opposite posts should not exceed 5 mm, the difference in diagonals of metal doors up to 2 m in size should be within 3 mm, for large openings - 5 mm;

The paint coating with primer is not less than 0.03 mm, and the protective coating should not cause allergic reactions upon contact with the palms of the hands.

For your information! In addition to the above list, GOST requires checking the quality of seals, condition and performance of locking mechanisms and hinges.

The resistance of swing metal structures to shock loads from wind is tested by dropping the folds assembled on the frame under their own weight onto a non-destructible object. Based on the results of the tests, the manufacturer issues a passport and applies markings in accordance with GOST. The encoding indicates the VM model - metal gate, GOST number, product dimensions.

Features of metal gates with swing doors

Each gate design has its drawbacks, and systems with swinging halves also have them. Using the principle of drop-down metal halves is very convenient for small openings of 2-2.5 m.

In the standard version of small driveways, the design of the entrance gate is assembled similarly to the design of metal garage doors. In this case, hinges are welded onto steel vertical posts made of channel or I-beam and sashes are hung from sheet metal thickness 3-5 mm. Due to the fact that the structure of the shutters is heavy, and there is no upper horizontal beam, as in metal garage doors, there is a risk of the pillars skewing and the shutters lowering. Rigidity problems can only be solved by installing very powerful support pillars, steel, brick or reinforced concrete.

The wider the passage, the more the gate leaf will weigh, which means it is more difficult to ensure a stable position and the absence of sagging of heavy leaves due to wear and bending of the hinges. In addition, the area of ​​the gate structure increases, which means the windage and horizontal load from gusts of wind increases .

Therefore, for passages more than three meters wide, special structures are used:

Forged swing gates. Very beautiful and expensive designs made of forged rods with individual style and artistic forging patterns;

Frame systems made of profiled sheets and tubular frames. Lightweight and inexpensive, easy to make with your own hands;

The doors are made in the form of two frames from a metal tubular profile with struts and spacers. The front surface is sewn up with profiled sheets or panels.

Aluminum swing gates. They have high rigidity and moderate weight of the structure; unlike the forged version, aluminum gates are always of the same type, differing only in the elements of the front surface cladding and the drive system.

Important! The safest option was to purchase swing metal gates from a specialized company or organization that supplies finished goods. In this way, most mistakes associated with incorrect calculation and manufacture of basic elements can be avoided, for example, installing hinges on the frame and leveling the supporting frame to the horizon.

Practical swing gate designs

Each of the listed options, in fact, reflects a modern view of the main functions of the gate. Option one – protective and decorative functions characteristic of forged steel structures. The second is a fast-acting and lightweight version of aluminum swing gates, the third is reliable and convenient, inherent in steel gates made of profiled sheets.

Forged swing gates

They are best suited for protecting access to a private property. The forged steel frame of the doors is capable of withstanding the most severe load, significantly exceeding the standard 200 kg, defined by GOST as a base value. In the most expensive and beautiful versions, all parts of the doors are forged, from the outer frame to the internal lintels and decorative details. In cheaper metal versions the main strength elements, the frame of the sashes and lintels are welded from ordinary pipe, forged parts only complement the appearance.

Forged sash frames are hung on hinges to the embedded elements brick pillars. The lower part is covered with a cladding made of thin sheet metal, top part The doors can be completely open or have decorative inserts made of darkened polycarbonate.

Forged gates are much more difficult to manufacture than conventional frame gates due to the large number of welded parts. To reduce the influence of thermal stresses and achieve a standard two-millimeter gap between the sash and the fixed frame, metal gates They are welded in the form of one sheet, the hinges are welded and hung on poles, and only after that they are cut into two sashes.

Aluminum swing gates

The second style is a modern business style, in which the doors open and close quickly and clearly, as much as possible using modern drive mechanisms. For example, the stopping power of aluminum swing gate leaves is not considered by the manufacturer as the main property; fast and flawless operation of the device is much more important. Most often, service parking lots and controlled areas of companies and firms are equipped with aluminum frame swing and sliding structures. In addition to automatic swing panels, the entry mode is controlled by a security guard.

The gate is a classic example of a swing system. The structure is made by argon welding of a profile with a cross-section of 96x177 mm from high-purity aluminum. Each sash is suspended on concrete pillar using triple loops with an increased size of the supporting surface. Internal diagonal braces made of cables and a support “patch”, which serves as a support and limiter of movement, help to compensate for possible deformation.

The manufacturer of swing gates claims a device life of 25-28 thousand operations, with a guarantee against corrosion for 15 years. The door leaf is made in the form of a cladding made of aluminum profile or sandwich panels. The cost of the structure greatly depends on the width, for example, a 2000x3500 mm gate of the ADS400 system will cost just over 50 thousand rubles, a 2300x3500 mm door is estimated at 75-77 thousand rubles, and 2300x5000 mm - all 90 thousand rubles.

Steel frame schemes

Frame metal doors made of pipes and profiled sheets can be called the most modern and practical option. Firstly, it is quite possible to assemble such a structure with your own hands. Secondly, the steel frame made of pipes is only slightly inferior in strength forged gates. Thirdly, such metal gate systems will cost much less than aluminum and, especially, forged ones.

The external cladding can be quite simply selected from a huge number of colors of profiled sheets. The construction of frame options is based on the same technology as when constructing a fence. Average weight two leaves of a three-meter gate will not exceed 300 kg.

Conclusion

When choosing the sizes of swing metal gate structures, experts recommend being guided by the principle of sufficiency and expediency. For an area fenced with a metal profile fence or modular sections, a metal swing scheme made of aluminum or steel profile is perfect. For a stone fence best choice There will definitely be a forged scheme. Thus, the style and durability of the gate will correspond to the material and structure of the fence.

DIY installation of a socket box

An iron garage is an inexpensive and fairly reliable shelter for a car. It will solve many pressing problems: it will hide the car from bad weather or the hot sun, accidental damage and prying eyes; you can carry out simple car repairs, diagnostics or other preventative work in it.

Usually, few people think about the weight of a building, but sometimes a situation arises when a car owner needs to know the weight of a metal garage, so in this article we will talk about the types of metal garages and provide calculations for buildings made of different facing materials.

Types of metal garages

Garages with a frame made of steel structures (see) are considered metal, although they can be sheathed with various materials.

They are divided into two types:

1. All-welded structures are mounted from sheet steel and all elements are connected by welding. Such a garage cannot be disassembled and can only be transported in assembled form. can be installed anywhere, it is particularly reliable against penetration and has strong connections.
2. have bolted or anchored connections of parts, the structure can be disassembled and transported in a compact form. This type is recommended to be placed on the territory personal plot or at the dacha, not far from the house, so that there is supervision, since it has poor protection against burglary.

Important! In turn, prefabricated structures can have different cladding, and this also determines how much an iron garage weighs.

The following materials are used for lining the walls of the structure:

• Sheet steel.
• Profiled sheet.
• Sandwich panels (see).
• OSB boards.
• Metal profile.

All these materials have different weight, therefore, when determining the mass of the garage as a whole, this must be taken into account.

How to calculate the weight of a garage

Data on the weight of the transported structure may be needed in the following cases:

• When purchasing a garage and having it delivered to permanent place. If the building was purchased from a manufacturer, then the seller provides data on the weight of the order, but when the garage is purchased second-hand, then in this case the weight is often calculated by the buyer.
• When transporting a garage to a new location (owner moving, sale, garage for demolition, etc.). If the structure was built with your own hands, the owner may not know its true weight.

For a sample, we will calculate the weight of a metal garage 3 x 6 x 2 m2 (width x length x height) of an all-welded type, in which the lining is sheet steel 4 mm thick. This is the minimum standard size, into which almost any passenger car will fit, well, except for minibuses.

So:

1. We calculate the area of ​​​​all surfaces of the garage:

• Side walls: 2m x 6m x 2pcs = 24 m2.
• Gable roof including canopies: 2m x 1.9m x 6.2m x 2pcs = 47 m2.
• Rear, end wall and gates: 3m x 2m x 2pcs = 12 m2.
• Two triangular pediments, the approximate area of ​​which is 4 m2.
• Floor (if any): 3m x 6m = 18 m2.

1. Adds all the results obtained: 24 + 47 + 12 + 4 + 18 = 105 m2.

1. For the walls we used sheet steel 4 mm thick; according to the table according to GOST, 1 m2 of such steel weighs 31.4 kg. We multiply the mass by the area: 105 m2 x 31.4 kg = 3297 kg.
2. We got the weight sheet iron, used for sheathing a garage. But that is not all! Now you need to add here the mass of the gate frame and the garage itself; it is usually made from a large equal-flange angle.

Let’s not make detailed calculations now; accuracy is not particularly needed here. Let's take an approximate average value, according to some sources it is 1000 kg.

Important! If we add up all the obtained values, we will see that the weight of a metal garage, all-welded, with sheet metal cladding 4 mm thick is 4297 kg.

Weight table for other materials

As mentioned above, garage cladding can be made not only from sheet metal. To correctly calculate the mass of the garage, you need to know their weight. In the table below we indicate these parameters for some of the materials most commonly found in garage decoration.

The weight of sandwich panels depends on the thickness of the insulation, and the metal profiles and corrugated sheets depend on the thickness of the metal. If you doubt the correctly determined parameters of the cladding, then to be on the safe side, it is recommended to take the maximum value.

Important! The choice of vehicle and the safety of transporting the structure depend on how accurately the weight of the garage is calculated.

Conclusion

We calculated how much it weighs metal garage 3 x 6 m, if the dimensions of the garage are different, then the mass of the building can be derived using the same system, replacing some data.

Typically weight iron garages varies from 3 to 7 tons, but if the first structure can be transported on a “thief”, then for the second you will have to order heavy-duty equipment and a truck crane. In addition, instructions for the transportation of large cargo require obtaining permits for the transportation of the garage, as well as escorting the cargo to its destination. All this is quite troublesome and costly, so it is better to immediately determine the mass of the structure as accurately as possible.

It must be said that after dismantling, prefabricated structures are assembled into compact packs that can be transported on an on-board gazelle. After looking at the thematic photos and videos in this article, you yourself will be able to cope with this task and accurately determine the weight of your garage.

How much do metal swing gates weigh?

How much do metal swing gates weigh?

Swing gates are one of best solutions for home, cottage, any private area. The design is not only functional and durable, but also durable. Swing gate frame, in any case, is made of reliably welded metal that is protected from corrosion. And if the doors are also made of metal, then the performance characteristics of the structure increase significantly.

The main advantages of metal swing gates:

• Durability, burglary resistance– they will provide excellent protection for your yard from the visit of “uninvited guests”;
• Durability– metal gates serve for decades without being influenced by external factors. They are resistant to mechanical damage, temperature changes, high humidity And ultraviolet rays. The leaf of most of these gates is coated with polymers and is therefore not subject to corrosion;
• Wide variety of design solutions. Gates can be made according to an individual project: have forging elements, inserts from other materials, and so on. Therefore create perfect interior- easier than it seems.

Metal gates are equipped with both manual and automatic drives. Automation greatly simplifies the control of the structure: to open/close the gate, just press a button on the remote control.
