Characteristics of fire doors
Gate version: The gate is made of steel frame and swing doors, made of three-layer metal panels, wall panels with three-layer mineral wool insulation (hereinafter referred to as PMTS), fixed around the perimeter in metallic profile. In one of the gate leaves there is a wicket door (in terms of design, the wicket gate is identical to the door of the metal fireproof blind series DMP-G 01/60). The design of the gate can be with or without a threshold, with or without a wicket door (at the Customer’s request). To seal the gaps in case of fire between the gate leaves and the frame, as well as between the frame and the gate leaf, a thermally expanding elastic material and a rubber seal are used.
Equipment:
Gate equipment: hinges, levers (for opening gate leaves), lock and handle, cylinder mechanism, closers (on both leaves); anchor bolts and decorative plugs for them. Instead of a closer, it is possible to install an automatic drive (at the Customer’s request).
Wicket kit(identical to the DMP-G 01/60 configuration): self-closing hinges - spring-loaded and structural (except for their direct functional purpose– opening/closing doors, also acting as a door closer), lock and handle from Nemof, cylinder mechanism, door closer (at the Customer’s request); anchor bolts and decorative plugs for them.
Coating, appearance:
The gates are painted with polymer powder paint; main colors are light gray shagreen (Ral 7032), or PMTS color (Ral 9002). On the outer surface of the Gate there is a metal nameplate with a fire safety sign, fire resistance limit (EI), serial number and date of manufacture, information about the manufacturer.
Gate weight
Installation into the prepared construction opening (license of the State Fire Service of the Ministry of Emergency Situations of Russia No. 2/21813) swing gates- 10% of the cost (see section “”). It is possible to manufacture gates for non-standard openings.

Sections of the article:
Choosing new door to an apartment as an entrance or interior, any person pays attention to the quality of workmanship, material and appearance. However, in some cases, one of the most important criteria when choosing is the weight of the structure. There are several reasons why reliable information is needed about how much a metal door or product made from other materials weighs.
Children and elderly people will not be able to open the heavy structure. There is also a high risk of serious injury when hitting a door with a large mass. In addition, one should take into account the need to create additional fastenings for products heavier than 60 kg.
What affects the heaviness of the product?
The main elements that directly affect the final weight are the selected material, the available filling, and their thickness. In addition, by weight interior door or entrance structure the following elements influence:
- Basic and additional fittings;
- Interior thermal insulation layer and its density;
- Sheathing elements;
- Thickness of the main fabric;
- Box.
Also, when calculating the mass of a composite structure made with decorative inserts other than the main materials, it is important to take into account the difference in the densities of the materials and the sizes of the elements. The size of the thin steel sheet used for the lightest blades is 0.8 mm. The thickest sheet is made in dimensions of 4 mm.
To reduce the total weight and, at the same time, impart significant strength to the product, stiffening ribs are placed inside, between the two main sheets. Between them, in most cases, to increase sound and thermal insulation, manufacturers lay polystyrene or mineral wool.
Nowadays by weight metal door the locking mechanism is significantly affected. In most cases, manufacturers equip blades with a set of 2 locks, the nominal weight of each of which can reach 7 kg.
Iron products
It is quite difficult to name the exact weight of metal doors, since iron can have different thicknesses and workmanship. However, approximate figures can still be derived.
The design of the simplest standard products weighs between 40-50 kg. The lightest are Chinese-made structures with powder coating and a steel plate thickness not exceeding 2 mm. Such products do not have any special decorative elements, and their weight is about 40 kg.
The most acceptable weight for a metal entrance door along with the frame ranges from 60-70 kg. This design often has decorative coating made of veneer or laminate, or trimmed with MDF panels. Products with expensive elements made from solid wood of natural origin usually weigh more than 100 kg. When producing high-strength doors with multilayer steel construction, the final weight of the door leaf is more than 150 kg.
It is important to remember how much the chosen iron door actually weighs. Because, despite high efficiency heavy elements, there is a rather significant drawback in terms of safety. Such products are not only inconvenient during installation, but also tend to deform during operation due to their own weight. That's why they're like that input elements require additional care in the form of systematic adjustment of the supporting loops and the position of the canvas itself.
The most massive products using steel are doors special purpose, namely:
- Models with increased fire safety;
- Armored systems;
- Products with improved anti-burglary characteristics.
Such structures can have a nominal weight of about 120-150 kg.
Interior doors
The weight of a structure made using plastic can be calculated by the ratio of the weight to the dimensions of the canvas. So, 1 sq.m of product contains 1.5 kg of material. If metal inserts are used inside the structure, the weight will be 2.5 kg per 1 sq.m.
The weight of wooden doors largely depends on the structure of the material used and the type of wood. The weight of the material made from solid elements of deciduous trees is more than 20 kg. per 1 sq.m. In the case of light and soft applications, often coniferous varieties wood, nominal weight wooden product decreases to 15 kg per 1 sq.m.
Using these numbers, it is easy to calculate the severity of a solid-type interior door. So, taking into account the weight of all the accessories necessary for the product, including handles and locks, the approximate data will be as follows:
- Plastic construction about 5 kg;
- Glass about 20 kg;
- Wooden, depending on the species, from 25 to 40 kg.
However, it should be remembered that the weight wooden door having constituent elements made of glass or plastic, can differ significantly from the solid-type design. The same principle applies to door elements that have different Constructive decisions, but at the same time made from the same type of materials. So, high door sliding type, when manufactured using natural elements, it will not be lighter than 100 kg.
A door made of MDF material can weigh no more than 10 kg, if it is made hollow or if cardboard filling is used. If the interpanel space is filled with tempered glass to enhance the heat-insulating and sound-absorbing qualities, the weight of the product increases significantly.
The heaviest structures made using solid natural wood materials are oak doors. Their weight can significantly exceed the weight of a metal door. The use of such massive structures at home is justified only if it is necessary to give a respectable appearance and with the obligatory presence of large free space and strong walls. Alternative option, in which you can get the same effect, but with a significantly lighter design, is the use of lightweight products using decorative veneering.
For guard local area from strangers and to ensure convenient entry to the site, swing metal gates are used. They are the final element of the barrier structure.
Despite the external massiveness of metal swing gates, they can be lightweight, so they are easy to open manually. The weight of the structure depends on the material of the swing gates, and the use of high-quality hinges ensures smooth movement of the gates.
Swing gates have a traditional shape. They do not limit the height of incoming vehicles. The doors can be made high and original patterns can be made on them.
Sometimes a gate is not needed at the gate, but in some cases you cannot do without it. For example, to go to country cottage area, it is better to make a gate, otherwise you will have to open and close the swing gates every time, and this is inconvenient. There are models of metal gates with a built-in wicket. It can also be installed separately.
Swing gates are most often made of metal, because... This is a durable and time-tested material. It is difficult to damage and can withstand bad weather. There are a large number of metal profiles for swing gates on the market, differing in appearance, performance characteristics and price.
Types of swing double-leaf gates:
- Swing frame gates with mesh. The mesh is attached to the top, providing access sunlight to the site. Such models of metal gates are safe (if you make the leaves high) and beautiful.
- Swinging metal gates made of corrugated sheets. This design is reliable, it hides the area from strangers. And wealth color solutions allows you to choose an option that matches the design of your fence or home.
- Welded swing gates. They can be made from welded mesh or from durable steel rods. The peculiarity of such metal double-leaf gates is that they are durable, inexpensive, can be erected in 1-2 days and provide an unobstructed view of the site. They are installed both at dachas and at industrial enterprises - they are universal due to their simplicity and reliability.
- Metal swing gates with forged elements. They are more expensive than ordinary ones, but they look impressive thanks to their elegant patterns.
There is another subtype of metal double-leaf gates - combined. The door leaf is made of corrugated board, wood or other material, and forging is located on the outside, on top or on the sides, decorating and strengthening the structure of the swing gates.
According to the control method, metal swing gates are distinguished with manual and automatic control. The first type is cheaper, and the second is more convenient. Automation does not require much space and can be installed even in limited space.
Before installing swing double-leaf gates, you must call a surveyor. He will measure the opening, listen to the client’s wishes, help select the material of the canvas and the type of automation so that the customer can use it conveniently.

Gates are a key element of fencing country house or garage. Swing systems made of metal are quite popular: being modern design, they have a lot of advantages, although they are not without disadvantages. This article will tell you what the pros and cons of swinging metal gates are.
Peculiarities
Swing gates are a large gate that allows cars or cars to enter the site. freight transport. Metal structures used in fencing are subject to the following rule: the higher and more monumental the fence, the larger and heavier they are, because the weight directly depends on the amount of material used in them. Externally, these are one or two doors mounted on poles, which, depending on the model, can open in any direction (inward or outward), be automatic or mechanical system opening.
In most cases, the gate has a small opening (small gate) that allows you to get inside without opening the gate itself. These systems are recognized as one of the most simple designs, they can be made in the same style with the fencing of the house (garage) or differ from it, being a bright accent against the background of the fence.
Swing gates require sufficient space for the leaves. They are equipped with beams with a load-bearing function, and it is important that the beams themselves are mounted at the same distance from each other to balance the gate. Swinging metal gates (with or without a wicket) consist of several elements:
- frame to which it is attached finishing material and decor;
- main metal cladding;
- loops necessary for fixing the frame;
- pillars, without which it is impossible to install gates;
- a locking mechanism by which a gate is opened and closed.
In addition to the main set of construction, installation cannot do without auxiliary raw materials (sand, cement, crushed stone, brick, paint), nails and appropriate equipment (grinder, square, level and welding). Installing swing metal gates with your own hands is simple and is carried out according to a pre-prepared drawing, which, if desired, you can draw up yourself, taking into account your own preferences or look after ready-made option, adjusting it to specific measurements and budget possibilities.
During the manufacturing process, the profile is coated with a special coating, which increases the resistance of the material to adverse influences. external factors. At the bottom of the profile beam, the models are equipped with special roller blocks, which are activated when the gate is operating. Due to the use of a corner connector, the sashes, which are attached using three-section hinges, do not sag. The appearance is beautiful because all fasteners in it are carried out mainly in a hidden form.
Advantages and disadvantages
Metal swing gates are easy to install. They can be installed into existing fencing. Having a solid and quite presentable appearance, These systems have a number of advantages:
- they are often equipped with a wicket built into the door leaf or located in a separate section;
- can have different, including ergonomic shapes, rarely make noise when the opening and closing mechanism operates;
- can be equipped with a safe automated system opening and closing with a remote control;
- differ due to the material of manufacture high level safety and durability, having resistance to corrosion;
- are made from various raw materials with high performance characteristics and degree of reliability;
- depending on the design, they decorate the fencing of the area adjacent to the home;
- with visible thoroughness, they are easy to install, their installation does not take much time;
- goes well with different building materials(wood, brick);
- have different heights, which allows you to get rid of the annoying looks of people from the street and protects against thieves;
- Based on the characteristics of the alloy used, they differ in cost, allowing each buyer to purchase an option taking into account taste preferences and the budget planned for the purchase.
These fencing elements, characterized by functionality and convenience, do not require special care. Being both protection and decoration of the fence, they serve for a long time without needing repair.
Thanks to the variety of modern styles and the presence the required material V construction stores metal swing gates can be made to order according to an individual sketch.
At the same time, you can play up the design features by painting the surface, forged ornaments, and, if necessary, insulate them or cover them with clapboard, which is especially important if these gates are part of a garage.
Minuses
Despite a number of advantages, metal swing gates have several disadvantages:
- their installation requires a lot of space;
- When installed, beams must be buried deep in the ground, which is not always possible;
- they cannot be installed without concreting the pillars, which takes some time;
- if there is insufficient concreting, the pillars will warp the entire structure over time;
- a certain space is required for opening and access, otherwise comfortable use of the gate is impossible;
- When equipping the structure with an electric drive, their cost increases.
In addition, metal swing gates are difficult to use in strong gusty winds: with a mechanical drive it will be problematic to hold them.
Types of structures
Swing gates made of metal come in different varieties. In addition to solid structures, lattice varieties with different designs and manufacturing method. Having a mechanical or automatic drive, they are divided into several varieties:
- frame with mesh – systems with different decorative elements made of a tubular frame, characterized by lightness, reasonable cost and ease of manufacture (you can make it yourself with your own hands);
- varieties made of corrugated sheets with forging elements - durable designs with a wide range of colors and design design, which are systems closed type;
- mesh (lattice) forged - expensive gates made of forged rods, made with artistic forging, characterized by the strength of the frame itself;
- insulated - varieties whose use is associated with harsh climatic conditions (models for garages or other heated non-residential premises).
The choice of the right variety depends on the budget and the features of the fence itself. It is important to choose the gate so that it matches the fence in color or style.
Requirements
Swing gates are subject to certain requirements of GOST 31174-2003 with clearly defined requirements. At the same time, the subtleties of design and nuances of characteristics can be determined during design. Since metal in large quantities has a corresponding weight, several requirements must be taken into account for flawless and correct operation:
- the movement of the doors must be free: for this, the size of the gate is selected or calculated taking into account the dimensions of the existing transport;
- the minimum permissible distance from the pillar to the side of the vehicle should be 30 - 35 cm;
- the gate must be burglary-resistant: the thickness of the galvanized sheet must be at least 2 mm;
- to ensure protection from rain and snow, it is necessary to use vertical locks in the structure to secure the canvas and prevent distortion;
- the mechanism for opening and closing the gate and the corresponding components must be manufactured in strict accordance with the design documentation and calculations of the manufacturer;
- excluded visible defects metal surface;
- when treating the surface with a paint and varnish composition, its thickness should be at least 30 microns;
- the minimum height of products used for the private sector should be about 3 m (for industrial enterprises this figure is 5 m);
- the strength and continuity of welding seams must comply with GOST;
- components, frame and frame are selected with a double margin of safety, having confirmation of the quality mark in the form of a corresponding certificate of the State Sanitary and Epidemiological Supervision regulations.
Materials
Swing gates are made from various raw materials, including metal profiles. In order for them to be practical, reliable and durable, the choice of material is approached with all responsibility. Firstly, reliability and strength depend on this, and secondly, the weight and peculiarities of the installation technology. They try to use durable raw materials for cladding. Having chosen wood as a basis, need to take care of additional protection from rotting and antimicrobial treatment. This will extend the life of the material.
If you plan to use corrugated sheets, you should give preference to classes C, H or HC.
The raw materials for the frame are different, but are subject to the characteristics of the drive. The welded type is durable and reliable, but due to its heavy weight it is completely unsuitable for automatic gates. In this case the best solution There will be aluminum, which is lightweight. The bolted frame is quite simple to manufacture, but of all types of material it has the shorter service life.
The best material for the pillars is brick. It is strong, durable and can withstand heavy weight metal frame and the entire structure as a whole. Concrete is a worthy competitor to it: this material, in addition to high reliability indicators, allows redecorating and surface treatment, so that the pillars can be decorated taking into account the stylistic idea chosen for the design.
To ensure that metal swing gates serve for a long time and do not require repairs, it is worth taking note Some recommendations from professionals:
- It is advisable to use metal for the frame: it is more durable than wood, more resistant to negative natural factors And mechanical damage;
- if the design provides for surface painting, you first need to treat the metal with sandpaper to prevent the appearance of rust, cleaning off welding stains;
- if you need to degrease the surface, you should use any solvent;
- if it is necessary to insulate the gate, this should be done on internal surfaces sashes using expanded polystyrene or mineral wool, excluding the formation of air pockets;
