This standard applies to steel door blocks with installed locking devices (hereinafter referred to as door blocks or products) for buildings and structures for various purposes.

The standard does not apply to door blocks for special purposes in terms of additional requirements for fire safety, explosion and bullet resistance, exposure to aggressive environments, etc., as well as to door blocks of protective cabins according to the current regulatory documentation.

The scope of specific types of products is established depending on the operating conditions in accordance with the current building codes and regulations, taking into account the requirements of this standard.

GOST regarding metal fire doors, requirements for them and features of operation.

What are the requirements for GOST?

To protect production, personal property and other valuables from damage as a result of fire, as well as to maximize the localization of the fire itself, it is necessary to install special fire doors. They are able not only to withstand very high temperatures, but also comply with all safety standards and requirements. Unfortunately, not all manufacturers are responsible for their work, which means that in order to choose a really high-quality product, you need to know what features should be inherent in fire doors. This is what will be discussed next.

In most cases, fire resistant metal doors are installed as an emergency exit. In accordance with the current GOST 31173-2003, they must have locks, but, at the same time, they can be opened quite easily. GOST prescribes the manufacture of metal fire doors in such a way that, if necessary, even a child can use them. Considering the fact that in the event of a fire, door handles can become very hot and leave burns upon contact, GOST obliges to make a special button on the doors, or to connect the opening mechanism to the middle bar, while maintaining the minimum force required to open.

As for the door opening itself, for the most convenient, safe and efficient use, the doors should open towards the exit. In this way, the accumulation of a large number of people directly at the exit can be minimized.

Particular attention should be paid to the material used for finishing. First of all, it should not be afraid of the direct impact of fire, melt, and even more so ignite.

In the event that at least one of the above nuances is not observed, this can have an extremely negative impact on the life and health of people. If all the norms and requirements prescribed by GOST 31173-2003 are fully complied with, this will not only prevent the spread of fire, but it is also likely to save someone's life.

If you pay attention to the requirements that apply to fire safety, and, as a result, to fire doors, at various enterprises, then they are, in fact, almost the same type.

first of all, the door should withstand direct fire as long as possible, but at the same time not melt or deform;
prevent the spread of smoke and carbon monoxide;
easy to open.

Production features

In accordance with GOST 31173-2003, for thermal insulation and design of fire doors, it is allowed to use only those materials that are not subject to ignition, even under the influence of direct fire. Similar requirements apply to consumables. Among other things, handles, fittings, locks and other elements must have a minimum thermal conductivity. Only in this case, they will maintain a sufficiently low outside temperature and will not cause burns when in contact with the skin. Decorative trim is simply missing.

As for the exterior finish, only those compositions and paints that are fireproof can be used for it, due to which additional protection against fire is provided for the door.

Based on the above requirements, not all manufacturers have a license allowing the production of metal fire doors. The main condition for obtaining it is the availability of special equipment capable of producing products of the appropriate quality.

Where are fire doors used?

Despite the fact that the production of fire doors requires the use of specialized materials with fireproof properties, the cost of the products themselves is quite acceptable.

As a rule, the main objects where such doors can or should be installed are production workshops and premises, service stations, private houses, warehouses, as well as special-purpose premises.

In fact, this list can be continued almost indefinitely, the only thing that remains is that the fire door is installed in those rooms that need to be protected from fire.

Design features of fire doors

fire door design

In accordance with GOST 31173-2003, there are 2 types of features that should be paid special attention to:

First of all, we are talking about the availability of documents that allow an organization to engage in the production of metal fire doors, that is, the availability of a license. Among other things, each door must have an appropriate quality certificate and an individual passport, which indicates the main characteristics of the product, permissible temperature conditions and other parameters.

Related article: Infrared warm floor under the tile: do-it-yourself installation

If you study GOST 31173-2003 in more detail, you will notice that each fire door must have certain visual features. Let's consider them in more detail:

Mandatory design feature of a fire door	Note
No through holes or slots	Checking this is easy enough. It is possible to provide a light difference in two adjacent rooms. If the gaps are visible, it means that the door has gaps and its quality no longer corresponds to that which should be in accordance with GOST
You should pay attention to the seal that runs along the perimeter between the frame and the metal door leaf	The seal should not have even small cracks, and be as elastic as possible to the touch.
An important role is played by the softness of the closer	for the most efficient, safe and comfortable use, the closer should move smoothly enough, but not require additional effort to function
Notice the awnings	As practice shows, many companies install awnings, but they completely forget that a new product does not always have a lubricant. Among other things, given the specifics of the metal door itself, the lubricant used for the hinges must also have fire-resistant characteristics and properties, that is, withstand higher temperatures.
Locking mechanism	Even a light “bite” in the castle is strictly not allowed. It should work as smoothly as possible and not require much effort when opening and closing. Otherwise, it can lead to extremely unpleasant consequences.

What is GOST R 53307-2009?

GOST R 53307-2009 is used when testing metal fire doors. It is he who guarantees that the product corresponds to the quality and is able to save not only property, but also human life from fire.

Those products that have successfully passed the tests and received the appropriate certificate have some important features, such as the highest fire resistance, which allows these metal doors to be installed both in offices, private homes, as well as in large enterprises. Among other things, in accordance with GOST R 53307-2009, all products have the following characteristics.

Keywords: door blocks, door leaf, frame, steel sheet

The manufacture of steel doors is standardized by GOST 31173-2003, which has been in effect since March 1, 2004, and SNiP. These documents apply to steel door blocks equipped with locking devices, which are installed in residential and non-residential buildings. But special-purpose doors with increased requirements in terms of security or resistance to aggressive environments do not fall under their action.

There are a number of requirements for entrance metal doors.

Classification of steel doors

Depending on the location, metal doors are divided into external and internal structures. External metal doors are installed at the entrance to the building, in the vestibule. Internal steel products include entrance doors to housing from the entrance, installed inside buildings.

In terms of design, metal products differ:

by box type
the number of paintings;
number of sealing circuits.

There are no restrictions on the choice of finishes for metal doors, so the exterior design can be done with the following materials:

paint and varnish;
film;
leather;
woody;
glass (mirrors);
decorative metal.

Varieties of metal doors by type of finish

The door structure is made with a closed loop (K), a U-shaped box or with an additional (structurally separate) threshold (P). Steel doors can have a single-leaf (L, R) or double-leaf (D) leaf, which opens outwards (H) or inside (Vn) of the room. At admissible opening of both halves or one. According to the number of sealing circuits, the products are divided into single-circuit or multi-circuit.

The design features of metal doors are displayed in the identifier, for example, DSV LPVn 1900-800 MZ. This example is decoded as follows:

DSV - internal steel door block;
L - single-field with opening to the left;
P - with a threshold;
Vn - opens inward;
1900-800 - product dimensions;
M3 - strength class.

The operational characteristics of the design divide the products into classes. The table shows the values by which the classification is carried out.

Metal steel doors differ in strength class, which has the designation: M1, M2, M3. The strength class is determined by the results of tests that are carried out to determine the resistance to static, dynamic and shock loads.

The device of the input blocks is divided into types of execution according to burglary resistance:

conventional type, with anti-removable devices;
reinforced type, when the device is equipped with a perimeter locking mechanism, has reinforced hinges and strength class M2;
protective, with additional protection requirements and class M1.

Locks installed in metal door structures must comply with the recommendations of GOST 5089.

The thickness of steel sheets for ordinary metal doors according to GOST cannot be less than 2 mm. Armored products are made from metal sheets with a thickness of 8 mm. Reinforced and protective type of product is indicated by the letters "U" and "Z".

door requirements

The design of the product and its installation must comply with GOST and SNiP. Steel door leafs are made of sheets and rectangular profiles. The use of a bent profile is allowed. Also, the sheets can be connected to each other according to the type of a bent box, but GOST recommends connecting the sheets by welding, which is performed in a protective gas environment. The points where the connection is made by welding must be reflected in the documentation. The profile in corner joints is joined by welding or by another method. The strength of joints cannot be lower than welded ones.

The design of a metal door must comply with GOST and SNiP

Insulated metal doors are made of steel sheets with filling between them, for which mineral wool, fiberboard sheets, wooden blocks, foam plastic are used.

Door frames are made of a bent or rectangular profile, having, respectively, a thickness of at least 1.5 mm and dimensions in a section of 40x50 mm.

The canvas is reinforced inside with profiles located vertically and horizontally. GOST recommends using from two vertical and horizontal profiles. In the area where the door hinges and anti-removable mechanisms are located, additional horizontal profiles are installed, and in the rest it is allowed to place others at an angle between the vertical profiles.

The inner side of the doors is allowed to be made not from a solid steel sheet, but from parts connected by welding along profiles. GOST allows replacing internal metal sheets with fiberboard or other materials with the required strength.

Additional requirements

To be able to provide access to the locking devices in order to replace or repair them, a “window” is mechanically installed on the inside of the leaf. The locking device is not recommended to be fixed by welding due to the possibility of damage to the lock parts by high temperature. When installing locks, it is necessary to exclude the possibility of deforming loads on the locks during operation. This is necessary to prevent jamming of the locks.

To soundproof and reduce heat transfer, sealing gaskets are mounted around the entire perimeter of the box. The number of circuits is allowed two or more. Installation is carried out without gaps in the joints of the gaskets, and their fit to the porch must be made tight. On external entrance doors, sealing gaskets are selected according to their resistance to the influence of temperature changes. The depth of the lock bolt in the box socket is 22 mm.

Anti-removable crossbars must be installed in the area of the door hinges. Passive crossbars (pins) are welded or pressed.

Anti-removable bolts fit tightly into the holes on the door frame, preventing the door from being removed from the hinges.

GOST extends its requirements to the installation of metal door blocks up to nine square meters. The dimensions of the canvases are not more than 2200 mm in height and 1200 mm in width.

Mounting Features

Due to the significant weight and increased requirements for burglary resistance, the installation of a metal door has its own subtleties. After dismantling the old door, it is necessary to prepare an opening so that the gap between the wall and the box does not exceed two centimeters. After placing the door block in the opening, they start leveling, ignoring the deviations of the plane of the doors and walls. To fix the position, wedges are used, which are driven in between the frame and the wall.

Wooden wedges are used to fix the door block in the opening.

After that, they begin to strengthen the structure. A wall is drilled through special holes and a pin is driven into the wall, which must enter the wall by at least 15 cm. When drilling holes, it is necessary to change the slope for each fixation point, which will complicate the work of possible burglars.

If the structure has a double frame, then every 20-30 cm between the wall and the corner of the loot, special metal wedges are driven in, which are selected according to the width of the gap.

The main installation work is completed by sealing the gaps with mounting foam.

Given the complexity of the work, which requires knowledge and special skills, we advise you to turn to professionals, and not do it yourself. Otherwise, even an armored door will not ensure the reliability of your home and the safety of property.

GOST 26433.0 7.2.4 Appearance, quality of welds, color and quality of finishing of products are evaluated visually by comparison with standard samples approved in the prescribed manner. Surface defects visible to the naked eye from a distance of 1.5 m in natural light of at least 300 lux are not allowed.

7.2.5 Adhesion (strength of adhesion of paint and varnish coatings to the metal surface) is determined by the method of lattice cuts according to GOST 15140.

7.2.6 The tightness and correct installation of sealing gaskets, door fittings, fasteners and other parts, color and absence of cracks in welded joints, marking and packaging are checked visually.

To determine the tightness of sealing gaskets, compare the dimensions of the gaps in the porches and the degree of compression of the gaskets, which should be at least 1/5 of the height of the uncompressed gasket. Measurements are made with a caliper or a ruler according to GOST 427.

The tightness of sealing gaskets with closed sheets can be determined by the presence of a continuous trace left by a coloring matter (for example, colored chalk), previously applied to the surface of the gaskets and easily removed after inspection.

mm and mass kg, from a height of fall according to 5.3.5 into the central zone of the sample.

Note - At the end of the test, the door blocks must remain operational, while the bolt of the lock and the latch must freely enter their mating parts.

Before and after testing the door units for failure-free operation, it is recommended to check the tightness of the seals in accordance with 7.2.6.

When testing door blocks for resistance to a static load acting perpendicular to the plane of the door leaf in the free corner zone, it is recommended to use the graph of the dependence of the deflection of the free corner of the door leaf on the applied load, given in Appendix D, to determine the strength class.
