In the process of choosing a metal entrance door in the product description, you can find widespread references to the fact that the products are different high quality. Only a knowledgeable and experienced specialist can conduct a detailed analysis of doors. What should ordinary customers do, for whom all entrance doors mostly look the same? We recommend contacting close attention to standardize manufactured products. IN Russian Federation State standards (GOST) have been developed and approved, indicating technical and other requirements that manufactured products must meet. To confirm compliance, certificates of conformity of an approved type are issued. It is believed that buyers who purchase metal entrance doors are fully protected in terms of purchasing and using the highest quality products. Let's take a closer look at the approved standard.

What standard applies to fire doors?

When choosing a high-quality metal fire door, you should adhere to the GOST 31173-2003 standard. It concerns steel door blocks with general locks. Standard fire doors are assumed that can be used in residential and industrial premises. At the same time, it is worth knowing that high security doors and performance characteristics(explosion resistance, armor protection, bulletproofness, resistance to numerous aggressive influences environment and so on) do not apply to the above standard.

GOST 31173-2003 describes the features of marking and classification of door blocks. At the same time, recommendations are provided regarding the use of a certain type of steel. The features of the frame, sashes, installation of locks and thermal insulation materials. In addition, recommendations are given regarding the finishing of the sash (external and internal sides).

A characteristic feature of the described standard is the fact that so-called “fire doors” do not directly apply to it. Moreover, there is simply no separate state standard dedicated to doors of this type. Therefore, GOST 31173-2003 applies to them by analogy. Mainly, as stated above, it describes the design of metal doors. In reality the situation looks like this. When manufacturing fireproof metal entrance doors, the manufacturer develops its own installations, which are most often referred to as “technical specifications”. They provide performance requirements regarding fire resistance. Such technical conditions (TU) are as close as possible to GOST 31173-2003. In order for manufactured doors to be considered fireproof, the manufacturer must obtain a special so-called fire certificate. It is valid for three years. After the certificate expires, you must obtain it again. The main condition for obtaining such a certificate is testing with a sample of the manufactured door. Tests are carried out in accordance with the recommendations and rules that are enshrined in the State Standard “Test methods for fire resistance of doors and gates” (number 53307-2009). During the combustion test in a special oven, one side of the web is heated to the limiting values. If the product successfully passes the test, it is assigned a certain fire resistance class, which is recorded in the issued certificate. The higher the class, the more expensive the metal door. Of course, a higher quality and fire-resistant door can be used not only in residential, but also industrial premises with elevated temperature.

What determines the fire resistance of a metal door?

There is a fairly widespread opinion according to which it is believed that the thicker the sheet of metal door leaf, the more resistant it is to elevated temperatures. This is wrong. In fact, the following features are of decisive importance:

1. Thermal insulator (insulation). GOST 31173-2003 provides for the possibility of using foam plastic, mineral wool, wood and particle fillers as insulation. For obvious reasons, such a heat insulator is not suitable for fireproof metal entrance doors. There are insulation materials on sale that are characterized by high fire resistance. How to qualitatively insulate a canvas with such material yourself or with the help of a specialist, read the material dedicated to this.
2. The distance (size) of the gap between the frame and the door leaf. Ideally, this parameter should not exceed a value of 3 mm. The greater the deviation from this indicator, the lower the fire resistance of the door block.
3. Self-foaming seal. Extremely useful material, which foams in the event of a fire. Foam fills the space between the sash and the frame. This helps to prevent the spread of fire and heating to some extent. door frame and canvases. And also prevent combustion products from entering the room.
4. Sealing gaskets. Those that comply with GOST 31173-2003 should be used. They should tightly cover the entire perimeter of the sash.

How to choose a quality fire door?

The main purpose of a fire door is to protect against the spread of fire for some time before the arrival of rescuers. Mainly provisions relating to fire safety(including those required for doors of this type) are contained in the technical regulations approved by the Federal Law of the Russian Federation No. 123-FZ dated July 22, 2008.

When choosing a fireproof metal entrance door, you should pay attention not only to the product conformity marking GOST 31173-2003, but also to the availability fire certificate approved sample. As mentioned above, it fixes the fire resistance class.

What is a fire rating? What are they?

Fire resistance class is an indicator that is assigned to a particular product depending on the indicators obtained during the combustion test of a metal entrance door. The main parameter is the period of time during which the door “resisted” the constantly rising temperature and exposure to open flame. The following main fire resistance classes are distinguished:

— Ei 30. The number in the name reflects the number of minutes during which the metal entrance door will be resistant to fire. This is a standard class, which is sufficient for use in residential and industrial premises, as well as public places.

— Ei 60. An increased fire resistance parameter for an hour indicates a sufficient reserve of time during which it is possible not only to wait for rescuers, but also to evacuate people from a burning building.

— Ei 90. Metal doors of this class are recommended for use in places with increased fire hazard. This could be production of the appropriate type, gas stations, workshops, kitchens, warehouses for fuel and lubricants and other facilities. An hour and a half is enough for rescuers to localize and put out the fire.

The main function of metal doors is to protect the room from external atmospheric influences, noise, as well as from unwanted penetration. Modern metal door blocks must meet the requirements of current regulatory documents, be strong and durable.

Specific requirements for steel door largely depend on operating conditions. In some cases, the design of a metal door requires installation additional funds protection, heat and sound insulation. Detailed information about this can be found in our article at .

Basic requirements of GOST 31173-2003 “Steel door blocks”

The main standard defining the requirements for metal doors is GOST 31173-2003 “Steel door blocks”. This GOST contains requirements for steel door blocks with locking mechanisms. The standard does not contain additional requirements for fire safety, bullet resistance and resistance to aggressive environments.

According to GOST 31173-2003, the metal door leaf must be a structure made of metal sheets and profiles welded together. Profiles can be used both straight and bent. Corner connections profiles should be connected by welding or other types of connections while maintaining structural strength.

The standard also imposes requirements on the door frame: it must be made of a bent profile more than 1.5 mm thick or from a rectangular profile with a cross-section of more than 40x50 mm.

Any serious door manufacturer is required to test its products for compliance with the characteristics regulatory requirements. As a result of testing, he is issued a certificate of conformity for the product. The seller must also have this certificate. Check it!

External and entrance metal doors must contain two or more sealing gasket circuits, installed without gaps and resistant to climatic and atmospheric influences.

The requirements of GOST 31173-2003 apply only to metal doors of the following dimensions:

• The area of ​​the door leaf is less than 9m2.
• The height of the opening doors is less than 2200 mm.
• The width of the opening leaf is no more than 1200 mm.
• The weight of the door leaf is no more than 250 kg.

Classification of doors according to GOST

GOST 31173-2003 offers several classifications of metal doors.

Metal door blocks are divided into the following types of purposes:

According to the type of construction, metal doors are divided into:

• Cloths with a closed box.
• With U-shaped box.
• With a U-shaped box with an additional threshold.

There is also a classification based on the number of panels and the direction of their opening:

• Single-sex.
• Double-leaf (the width of the door leaves can be different).
• With non-opening inserts (vertical or horizontal).
• Opening inward.
• Opening outwards.

Based on the number of sealing contours, door blocks are divided into:

• Metal doors with one sealing circuit.
• Metal doors with two or more sealing contours.

Need to remember

Even if you have installed a reliable one, manufactured in accordance with GOST requirements front door, do not neglect the use burglar alarm. Details about modern alarm systems can be found in our.

Metal door blocks can have the following finish:

• Paints and varnishes or powder materials.
• Artificial or Genuine Leather and insulation.
• Decorative film materials.
• Wood materials (natural or synthetic veneer can be used).
• Glass or mirror materials.
• Combined finish.

Also, metal doors are divided into several strength classes (M1, M2, M3) according to resistance various types static, dynamic and shock loads.

Requirements for materials and components

The materials and components used in the production of door blocks must be manufactured in accordance with approved standards and specifications.

The surface of the steel structural elements of the door leaf must be flat and smooth, free from cracks and distortions, permissible waviness on the front surface is no more than 0.5 mm.

Materials intended for the manufacture of metal doors and their components must be resistant to climatic influences. Steel elements must meet the requirements of GOST 380, GOST 1050 or GOST 5632 standards.

Sealing gaskets must be installed tightly, without gaps, around the entire perimeter of the box, and meet the requirements of GOST 30778.

Requirements for hinges, locks and other locking devices

Technical characteristics, method of fastening and location of locking devices and hinges are established in the working documentation. These parameters are influenced by the dimensions of the opening elements of the product, its weight, as well as its operating conditions.

The hinges are attached to the door frame by welding or on mechanical links. While maintaining the strength of the structure, the use of other types of fastenings is permitted.

Block 50% from the beginning of the article

Depending on the purpose and operating conditions, metal door blocks are equipped with bolts, closers, opening angle limiters, chains, eyes, etc. Fasteners and door hardware must comply with the requirements of GOST 9.303 “Metal and non-metallic coatings” and GOST 538 “Lock and hardware products” .

The installed locks and hinges should not interfere with the easy but reliable locking of the door leaf.

Requirements for finishing products

The type of finishing coating and quality of finishing are agreed upon by the manufacturer with the consumer and specified in the contract. The quality of finishing is assessed based on samples approved in advance with the customer.

The main criterion for choice facing material are operating conditions.

The main regulatory documents regulating the condition of metal surfaces, requirements for paint and varnish coatings and their designation are GOST 9.402, GOST 9.401 and GOST 9.032.

The first layer of coating is applied with primer paint, then protective and decorative materials are applied. More detailed requirements for the quality of surfaces with completed paint coating contained in the standards GOST 9.301 and GOST 9.032.

When using wood parts, you should be guided by GOST 2140, wooden surface should have a roughness of no more than 60 microns, and a rock moisture content of 8 - 12%.

The performance indicators of metal doors, including noise insulation parameters, are established in the design documentation and are tested in testing centers.

According to the requirements of GOST 31173, door blocks must have sound insulation of at least 20 dB.

There are 3 classes of sound insulation for steel door blocks:

Metal door blocks are divided into 3 classes of reduced heat transfer resistance:

Class 1 - 1.0 m °C/W or more
Class 2 - 0.70 - 0.99 m °C/W
Class 3 - 0.40 - 0.69 m °C/W

To ensure an adequate level of thermal insulation, external doors are equipped with at least two sealing loops.

Increased thermal insulation is also facilitated by the use of special materials for filling the door leaf (mineral or basalt wool, polystyrene foam, etc.).

GOST 51072-2005 requirements for security entrance doors

According to GOST 51072-2005 “Safety doors,” a security door is a protective device that has in its design a door leaf, a door frame and one or more locking devices and is resistant to established methods impact.
