Reliable fire doors are one of the preventive measures to ensure against fire safety. Our company produces, in accordance with GOST 31173 2003, metal fire doors. All of the company's products are certified and undergo appropriate inspection and testing.

What conditions does GOST set for fire doors?

Fire doors made of 1.5 mm thick sheet steel are able to resist the spread of flame. And increased air tightness door design may contribute to attenuation if there is no other source of oxygen in the room. After all, as you know, combustion is impossible in airless space.

Fire doors manufactured in accordance with GOST are door blocks that are classified into three classes according to their ability to resist heat transfer, water-breathability, and sound insulation.

1. Class 1 provides a heat transfer resistance of 1.0 m2 °C/W or more;

2. Class 2 – from 0.70 to 0.99 m2 °C/W;

3. 3rd class - 0.40 - 0.69m2 °C/W. Heat transfer resistance below 0.40 m2 °C/W is not subject to classification according to heat transfer resistance.

Heat transfer resistance is achieved through fireproof fillers with low thermal conductivity placed inside the door leaf.

Metal fire doors are manufactured at our company with the following types of frames:

· closed,

· U-shaped,

· U-shaped with a separate threshold.

Fire doors They are also divided by purpose (installation location):

· External, that is, doors leading from the street;

· Internal ( entrance doors to an apartment, to an office, installed inside a building).

As regulated by GOST, fire doors can have the following designs, differing in the direction and type of swinging:

· single-sided (right- and left-sided);

· Swinging outward or indoors;

· double-field, with canvases of equal and different widths;

· With blind horizontally or vertically built-in decorative inserts.

The frame of the door leaf is made of solidly curved steel profile, having high resistance to deformation. The melting point of steel is more than 700 o C.

Decorative finishing, appearance of fire doors

The definition of “fire door” does not mean that this product is welded or assembled from rough steel sheets without any finishing. Fireproof structures are no less attractive and aesthetic than conventional ones, and determines the appearance of fireproof doors, GOST 31173 2003. Based on this document, they are used as facing and finishing materials

· natural and synthetic leather,

· decorative polymer films;

· veneered or laminated MDF boards;

· wood, glass, plastic.

When choosing finishing materials, the conditions in which the door structures are expected to be used are taken into account. Except facing materials, polymer, powder, and paint coatings can be applied to fire doors, protecting the metal from corrosion and adding style and attractiveness to the entire structure.

How are fire doors tested?

When developing and creating a new door model, especially if new materials are used, the enterprise necessarily creates test samples that pass test tests regulated by state standards.

Fire Testing

Tests for the ability to withstand open flames are regulated by GOST 53303 2009. Fire doors are included in the list of building structures in this document. Fire resistance testing is carried out on bench equipment with measuring equipment. The list of equipment includes:

· Testing furnace with automatic feeding and combustion of fuel, providing a one-sided thermal effect on the tested object;

· The furnace has a block of smoke channels with an excess pressure regulator;

· Measuring instruments, recording the received parameters;

· A portable thermocouple that determines the temperature on a selected surface area on the unheated side, where a peak temperature increase is expected.

· A device that simulates test samples in operation.

The prototype for testing and all its component blocks must comply with the presented technical documentation for a specific model.

Smoke and gas permeability tests

Smoke-gas-tight doors are doors that block the spread of flame and smoke and are capable of resisting the penetration of gaseous combustion products into a room for a given time.

Testing for smoke permeability through the structures being tested is determined by GOST R 53307 2009 for fire doors and other fire-resistant building structures. The essence of this test is to establish how long a door, heated from the side of the fire, will be able to withstand smoke, how long during the test it will be smoke-gas-tight, being under the influence of increased pressure. During testing, the pressure difference is established at 70 Pa ± 10%. The highest value is set on the heated side.

This test also includes a special oven equipped with nozzles and simulating a fire in the room. Regulation and maintenance of the required pressure difference is ensured by a thermal fan with piping, control dampers and a flow meter.

The test bench is equipped with thermometers, gas flow and pressure meters. There are increased demands on the accuracy of instrumentation, including stopwatches.

The fire resistance limit, corresponding to GOST R 53307 2009 of metal fire doors and other building structures, consists of a fixed designation of the state when the product is able to resist negative influences, and a number corresponding to this time in minutes: S15, S30, S60. The fire resistance class is established based on the lowest testing values.

Tests on a testing stand and further measurements reveal weak points and shortcomings of the door structure, which are refined, brought to compliance with GOST 31173 2003 fire doors, and only then they are introduced into mass production.

What to look for when choosing a fire door?

What door characteristics should you pay attention to when buying a fire door? GOST for fire doors pays attention to locks. Metal fire doors are equipped with anti-removal devices that prevent the door from being removed from its hinges, and locks with security properties of increased and high categories of classes 3-4. Some locks are equipped with special systems that make it easy to open the door from the inside.

It is important that the internal filler is not flammable polyurethane foam, but mineral wool, glass wool - materials that can withstand high temperatures.

Our company produces fireproof products with a three-year warranty in Moscow, and is confident in the quality and reliability of the design of fire doors in accordance with GOST.

You can order a batch of doors for a residential building, office center, or other construction site in Moscow and the region. We will not only manufacture, but also deliver and install our products on site.

Fire doors - necessary element security on industrial enterprises, in shopping and office centers. They allow you to delay the time of penetration of an open flame into a room with people. Even in the event of a severe fire, such doors do not deform for at least 30 minutes and do not become an additional source of toxins. They are also installed in private houses and apartments so that extreme conditions the homeowners had a chance to get out of the premises or wait for help from firefighters. IN multi-storey buildings it is the fire door that may be the only chance for salvation. It plays an important role in extinguishing a fire and evacuating people from the scene.

Basic GOSTs

The requirements for a fire door are outlined in GOST, which specifies the fire resistance limit and other basic characteristics. Compliance with these standards provides protection against the penetration of flame and smoke into the room. To obtain a certificate confirming compliance necessary parameters GOST, it is necessary to conduct laboratory tests. The EIR marking shows the limit of structural integrity, thermal insulation properties and time before the door catches fire.

Classification of doors by type according to GOSTs

Fire doors are classified into three types:

Material of manufacture. They are made from wood, metal and glass. The latter allow you to see the source of ignition and the strength of the fire. Metal doors according to GOST can also be made of steel or aluminum. For each type, there are standards that the design must strictly comply with.
Type of construction. They are divided into single-leaf and double-leaf. Single-leaf structures consist of a frame and a door leaf, which opens only in one direction. In this case, the main requirement is to set the threshold. Double doors can be either equal or unequal, depending on the width of the leaves. It is important to remember that the doors double doors should open in one direction.
Degrees of fire resistance. Products come in three types: 1st, 2nd, 3rd. The fire resistance of doors mainly depends on the thickness and type of internal insulating layer.

Dimensions according to standards

Dimensions GOST regulates the testing of one standard door size for a specific manufacturer. The test results and dimensions are recorded in the protocol, the permissible deviation of which in height and width should not exceed +10% and -30%. The value is rounded only up to 5 cm up and down to 10 cm.

Permits for installation

Fire doors may only be installed in appropriate rooms. Since the main function of such structures is to protect people and property from fire, they are often installed in rooms with an increased risk of fire. In industrial enterprises this is warehouses, corridors, workshops, basements, attic floors and technical compartments. If the total area of the technical floor exceeds 300 m2, two fire-resistant structures must be installed, and the size of the doors should not be less than 0.75 * 1.5 m. In office centers, such doors are installed in rooms where important documents are stored.

According to consumers, a metal fire door has the highest degree of fire resistance. GOST obliges the use of alloy steel grades for manufacturing. Non-toxic fire-resistant materials are used as coatings and insulation. They also have sufficient fire resistance wooden structures, which were previously impregnated with special solutions that retard fire. Modern technologies make it possible to use aluminum profiles with heat-accumulating fillers and laminated fire-resistant glass for the production of doors.

There is no regulatory document regulating the installation of a fire-resistant door. However, to install a fire protection structure, a package of documents is required. It consists of a fire safety certificate, a passport for the door and a license to perform door installation work. You also need a well-functioning door closer that automatically closes the door. For installation, special non-flammable fireproof foam must be used. The metal structure must fit tightly to the box, leaving no gap. To ensure the reliability and durability of the door, the sealing rubber should be slightly compressed. Uniform painting, high-quality glued thermal expansion tape, and an adjusted closer will serve as the key to high wear resistance of the structure.

Fire door operation

Caring for fire doors is no different from servicing regular doors. metal structure, it is not regulated by GOST. Operation of both wooden and steel doors must be carried out throughout the specified service life. According to GOST standards, a door must be replaced if it has fulfilled its main protective function during a fire. The fire resistant fire door is then removed and replaced.

Fire doors made according to GOST , They are more expensive than regular doors, but they provide safety in case of fire. Even if the fire department does not require the installation of such a door, it costs much more than the additional funds spent. This design can save not only property, but also people's lives.

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

What are the requirements of 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 capable of not only withstanding very high temperature, but also comply with all safety standards and requirements. Unfortunately, not all manufacturers approach their work responsibly, which means that in order to choose a truly high-quality product, you need to know exactly what features fire doors should have. This is exactly what will be discussed further.

In most cases, fire-resistant metal doors are installed for emergency exits. In accordance with the current GOST 31173-2003, they must have locks, but at the same time, they must open quite easily. GOST requires that metal fire doors be made in such a way that even a child can use them if necessary. Taking into account the fact that in the event of a fire, door handles can become very hot and leave burns upon contact, GOST requires making a special button on the doors, or connecting the opening mechanism to the middle rod, maintaining the minimum force required for opening.

As for opening the door itself, for the most convenient, safe and effective use, the doors should open towards the exit. This is how you can minimize the accumulation of a large number of people directly at the exit.

Particular attention should be paid to the material used for finishing. First of all, it should not be afraid of direct exposure to fire, it should not melt, much less ignite.

If at least one of the above nuances is not observed, this can have an extremely negative impact on people’s lives and health. 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 also quite possibly save someone’s life.

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

first of all, the door must withstand exposure to direct fire for as long as possible, but 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 susceptible to fire, even when exposed to direct fire. Similar requirements apply to consumables. Among other things, handles, fittings, locks and other elements must have minimal thermal conductivity. Only in this case will they maintain a sufficiently low external temperature and will not cause a burn upon contact with the skin. Decorative finishing is simply missing.

As for the external finishing, only those compositions and paint coatings that are fire-resistant can be used for it, due to which the door is provided with additional protection from fire.

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 presence of special equipment capable of producing products of appropriate quality.

Where are fire doors used?

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

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 main thing remains 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 you should pay special attention to:

First of all, we are talking about the availability of documents that allow a particular organization to engage in the production of metal fire doors, that is, the presence 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.

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

Mandatory design feature of a fire door	Note
Absence through holes and crevices	It's quite easy to check. It is possible to provide a light difference in two adjacent rooms. If gaps are visible, it means that the door has cracks and its quality no longer corresponds to what it 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 should be as elastic to the touch as possible.
The softness of the closer plays an important role	for the most efficient, safe and comfortable use, the closer should move quite smoothly, but not require additional effort to operate
Pay attention to the awnings	As practice shows, many companies install awnings, but completely forget that the new product does not always contain a lubricant. Among other things, taking into account 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 light snacking in the castle is strictly prohibited. It should operate as smoothly as possible and not require much effort when opening and closing. Otherwise, this can lead to extremely unpleasant consequences.

What is GOST R 53307-2009?

GOST R 53307-2009 is used when testing metal fire gates. It is this that guarantees that the product is of high quality and can 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 in offices, private homes, and large enterprises. Among other things, in accordance with GOST R 53307-2009, all products have the following characteristics.

Note - Significant and critical defects include: defects leading to loss of performance characteristics that cannot be eliminated without replacing a part of the product (breakage of a steel profile, etc.), exceeding the maximum dimensional deviations by more than 1.5 times established in the RD, incompleteness of products. Minor defects include removable defects: minor surface damage, unadjusted door devices and hinges, exceeding the maximum dimensional deviations by less than 1.5 times established in the RD.

By agreement of the parties, acceptance of products by the consumer can be carried out at the manufacturer’s warehouse, at the consumer’s warehouse or at another place specified in the supply agreement.

6.9 Each batch of products must be accompanied by a quality document (passport). An example of filling out a product passport is given in the appendix.

6.10 Acceptance of products by the consumer does not relieve the manufacturer from liability if hidden defects that led to a violation of the performance characteristics of products during the warranty period.

7 Control methods

7.1 Methods of incoming and production operational quality control are established in the technological documentation.

7.2 Methods for quality control of products during acceptance control and acceptance tests

7.2.1 Geometric dimensions products, as well as the straightness of the edges, are determined using the methods established in GOST 26433.0 and GOST 26433.1.

Maximum deviations from the nominal dimensions of product elements, the difference in diagonal lengths and other dimensions are determined using a metal measuring tape in accordance with GOST 427, applied to the upper mating surface, to the lower surface.

7.2.4 The appearance, quality of welds, color and quality of finishing of products are assessed 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 (adhesion strength of paint and varnish coatings to the metal surface) is determined by the method of lattice cuts according to GOST 15140.

To determine the tightness of the sealing gaskets, compare the dimensions of the gaps in the recesses 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 ruler according to GOST 427.

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

7.2.7 Work door hinges checked by opening and closing the sash elements of the product ten times. If deviations in the operation of door devices are detected, they are adjusted and rechecked.

7.3 Methods of control during periodic testing

7.3.1 The reduced heat transfer resistance is determined according to GOST 26602.1.

7.3.2 Air and water permeability are determined according to GOST 26602.2.

7.3.3 Sound insulation is determined according to GOST 26602.3.

7.3.4 Indicators of failure-free operation, resistance to static, dynamic, and shock loads are determined according to normative documents and methods approved in the prescribed manner.

When testing resistance to dynamic loads, the load that occurs when a door leaf is suddenly opened (for example, during a draft) is simulated at the moment the door leaf comes into contact with the slope of the doorway.

The test for impact resistance of a soft inelastic body is carried out with a three-time impact, for example, with a punching bag with a bottom diameter of (300 ± 5) mm and a mass of (30 ± 0.5) kg, from a drop height ofto the central zone of the sample.

Note - Upon completion of the tests, the door units must remain operational, while the lock bolt and latch must freely fit into their counterparts.

Before and after testing the door blocks for failure-free operation, it is recommended to check the tightness of the sealing gaskets in accordance with.

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

7.3.5 Methods for quality control of welded joints () are established in the manufacturer's technical documentation in accordance with GOST 5264.

8 Packaging, transportation and storage

8.1 Packaging of products must ensure their safety during storage, loading and unloading operations and transportation.

8.3 Opening panels of products must be closed with all locking devices before packaging and transportation.

8.4 Products are transported by all modes of transport in accordance with the rules for the carriage of goods in force for this type of transport.
