Aluminum doors are very popular today, but in order to meet the declared characteristics, they must meet GOST requirements. Otherwise part useful qualities will be lost, and it will be unsafe to use them.

Requirements for products made of aluminum alloys are described in GOST 23747

Design and types

The door block consists of a frame and internal filling. The frame is made of aluminum, mainly double-glazed windows are installed between the profiles. Additionally, blind inserts are used, which can occupy the entire internal area or only the lower part, depending on the design.

According to the method of opening the door from aluminum profile are divided into the following types:

• hinged - standard doors with hinges that open in one direction;
• sliding – thin doors installed on a roller system;
• pendulum - variation swing structures, which open in both directions through the use of non-standard hinges.

Types of designs

Scope of use

Doors made of aluminum and its alloys are widely used today to fill openings in places with a large flow of people. Thanks to the characteristics of the material and the quality of the fastenings, the design is able to withstand heavy traffic without major functional changes.

Some types of aluminum doors are used in almost all office buildings, hotels, supermarkets, boutiques, salons and others in public places. Reliably protect the premises from external factors and intrusions by robbers at night. At the same time, they fit well into the surrounding design and are easily adapted to specific stylistic conditions.

Aluminum structures are common in public buildings with high cross-country ability

As for use in residential premises, such doors are mainly installed in modern apartment buildings with concierge and security. Lightweight models are used inside individual homes.

To a greater extent, such products are suitable for ultra-modern interiors in high-tech style, bright painted models are typical for fusion, pop art and the like.

Distinctive Advantages

Although aluminum does not have super strength, a number of characteristics distinguish it from other materials used for the manufacture of door structures.

Advantages of aluminum profile:

• Environmental friendliness. The material is safe to use, does not contain harmful impurities in its composition, does not emit substances hazardous to health and does not have a radioactive background.
• Ease. Despite the fact that aluminum is still a metal, structures using it look quite elegant and are surprisingly lightweight, which simplifies the process of their transportation, installation and further operation. On door frame, walls and other load-bearing elements of buildings are not subject to heavy loads.
• Durability. The material is quite durable and resistant to abrasion, even if the conditions for careful handling are not met.
• Wear resistance. Aluminum doors can withstand 100,000 opening and closing cycles and withstand adverse conditions well external environment, they are not afraid of strong winds, precipitation, frosts and sunlight. Aluminum does not corrode, withstands mechanical loads and shocks well, and does not react to household chemicals.
• Design. Although aluminum and its alloys belong to the category of metals, this material can be used to create very elegant door models. In addition, it can be repainted and brought into different shapes by combining it with other materials.
• Plastic. Aluminum can be easily processed in production, making it possible to constantly expand the range and create amazing door models at minimal cost.

Environmental friendliness, lightness and durability are the main advantages of aluminum structures

Despite such significant advantages, not all products that go on sale meet the declared characteristics. To positive traits were fully disclosed, every detail of the aluminum structure must meet the requirements of GOST standards.

In addition, such models may not always fit organically into the interior of the room. This is important to consider when choosing a door structure for a residential or public building.

Primary requirements

The main regulatory document is considered to be GOST 23747 “Door blocks made of aluminum alloys”. The requirements described in it are divided into several categories. The first of them concerns directly technical characteristics products and general provisions regarding the design.

Each aluminum door must be tested for resistance to heat transfer and air permeation. Acceptable standards are regulated by separate documents: GOST 26254 and 25891. In addition, products must withstand severe static loads and withstand at least 100,000 opening and closing cycles without compromising integrity or reducing quality. It is important to take into account that the applied force should not exceed 50 N.

Regarding design and other design features, the door can be completely glazed or divided into solid and transparent. The size of the lower section is allowed no more than 1 m to the lightproof part.

Full or partial glazing is considered a design feature

GOST standards provide for the production of a frame from extruded aluminum profile. The type of materials and their parameters are also regulated in order to prevent metal twisting and rapid wear of the structure during operation. Fasteners are made from, established by standards grades of steel. To fill the frame, it is allowed to use sheets and extruded profiles with a thickness of 5-6 mm. The glass in double-glazed windows should be the same thickness, the total size of which ranges from 15-28 mm. Protection must be provided to prevent the door from being dismantled for the purpose of breaking into it.

The maximum deviations of the dimensions of the box and the canvas are regulated by separately derived values ​​for each typical case; they can fluctuate between 0-1.5 mm.

Sealing and insulation

First of all, you should pay attention to the maximum allowable dimensions of the gaps between the frame and the door leaf. Along the perimeter they cannot exceed 3 mm. If you consider the doorway from the front side, when installing the product, the difference with the frame should not be more than 2 mm. The gaps when installing double-glazed windows and other parts at their connection points are 0.3 mm. It is possible to increase this space by up to 1 mm, but in this case, in addition to glazing beads, additional sealant must be used.

As for filling the joints itself, sealants without glue are used on the rebates and at the joints of the frame. They must be of such a size that in the closed position there is no gap between the box and the canvas. Continuous gaskets made of light-ozone-freeze-resistant rubber or plastic are required on each side of the perimeter. It is permissible to use sealant as an alternative. The types of glue used are regulated by GOST 23747.

To fill the frame, support and fixing spacers with clearly defined minimum sizes made of low-density polyethylene, ozone-freeze-resistant rubber or wood with antiseptic treatment.

Schematic illustration of filling the aluminum profile frame

External covering

No less important question concerns the design and protective layer. According to GOST, the following materials are allowed:

• mandatory treatment with an anodic paint and varnish composition, except for the structure liners;
• during the manufacturing process of the product, the type of anodic oxide coating is separately agreed upon;
• according to GOST it is recommended to use paint and varnish materials third class;
• the thickness of the applied layer is set to at least 70 microns;
• the absence of an outer layer in inconspicuous areas of the product is allowed due to the mechanical processing of these areas;
• After assembling the structure, anodic oxide, zinc and cadmium coatings cannot be applied.

In addition, it is important to consider quality requirements metal surface. The limits of permissible defects are documented in GOST 9378. If the standards are not met, door blocks made of aluminum profiles should not be allowed for sale and further use. If the manufacturer complies with all the specified requirements and takes into account the wishes of the customer, the result will be an ideal aluminum door.

Sections of the article:

GOST for aluminum door blocks was developed and implemented back in Soviet times. But this one is still normative document used in the production of such structures. Aluminum entrance doors especially popular. To be convinced of this, you just need to look around and see that these structures are installed in shopping malls, public institutions and other facilities.

Areas of use of aluminum door blocks

The high popularity of aluminum doors is easy to explain. They are distinguished by their reliability, high strength, and wide variety. Their design is quite complex, requiring strict adherence to certain standards and technical recommendations during the manufacturing process. If these rules are not followed, unpleasant consequences may occur. Similar door designs began to be actively used during the existence of the USSR. That is why they were then standardized to the required regulatory documentation, which manufacturers still rely on when producing aluminum door blocks to this day.

The state standard regulating the production of such door structures was prepared, adopted and put into effect by Gosstroy Soviet Union in January 1989. This GOST number 23747-88 is called “Doors made of aluminum alloys” and divides door structures according to a number of characteristics. In addition, it obliges manufacturers to follow certain technical requirements when producing such doors.

Aluminum doors have a whole range of unique qualities, which promotes their use in public institutions, as well as private houses and apartments. Aluminum door blocks are different modern design and correct geometry, which remains unchanged during active and long-term use. In addition, such doors are characterized by strength and excellent resistance to impact. atmospheric phenomena. It is safe to say that aluminum doors are a special type of entrance.

GOST for these structures allows their use in different climatic zones. To these door blocks There are no special requirements regarding thermal insulation. Despite this, aluminum structures have proven themselves well as entrance and interior doors. In addition, their thermal insulation to the required extent is allowed. Along with this, aluminum doors are characterized by high structural rigidity, which allows these products to be used in the most different conditions, including extremely unfavorable ones.

For example, aluminum doors can be successfully used in public institutions with increased human flow. They can withstand many cycles of operation without significant wear.

Types of doors used

The basic designs of aluminum door blocks, fixed in GOST 23747-88, must comply with certain requirements. This state standard does not apply to products that are not made of aluminum alloys. In addition, this GOST does not apply to special-purpose structures.

These include sealed, fire-resistant and smoke-resistant aluminum doors. It should be emphasized that aluminum doors can be used not only as entrance doors, but also as interior doors in offices, apartments and private houses. True, such products for the most part differ not in the profile itself, but in the fittings.

Differences between aluminum doors by opening method

Aluminum doors can be divided into a number of types depending on the design. The most in demand and popular are swing doors. This classic version, which involves fixing the door leaf on hinges attached to door frame. Such doors open and close by pressure with human hands. Aluminum swing doors can be single-leaf or double-leaf and operate on the same principle as similar structures made of other materials.

Another popular type of aluminum doors are sliding structures. The peculiarity of the functioning of such products is that the doors move apart in opposite directions or they overlap one another. In addition, pendulum aluminum structures are also widely used. They are especially effective in areas with a large number of people. The exclusivity of this system is, first of all, characterized by the ability to open the sash in any direction.

Separation by profile type

In accordance with GOST 23747-88, aluminum doors can be made from two types of profiles: warm or cold. The first type got its name due to the use of an additional polymer component in the structure, the task of which is to prevent the product from freezing when low temperatures. To achieve this result, it is necessary to seal the entire contour of the sash with a double layer. In addition, this helps prevent cold air and moisture from entering the premises.

The cold aluminum profile is not equipped with such a polymer insert. This should be taken into account, because when using structures made of such material, the temperature inside the room and the door itself will be almost identical to the outside. Products made from cold profiles are well suited for utility rooms and warehouses that do not need to be heated. It is worth emphasizing that in areas with a vestibule you can use a combination of door groups from both types of profiles. This good decision for such premises.

Features and advantages of aluminum door blocks

The long-term popularity and increasingly widespread use of aluminum profile products indicate a number of advantages of these doors. First of all, we should highlight the aesthetic characteristics of aluminum door blocks. Even in very large products, thanks to the use of narrow aluminum profiles, it is possible to achieve large area glazing to allow light to pass through. It is also worth highlighting the long service life of these structures. Most manufacturers provide long warranties. As a rule, the service life of doors made of aluminum significantly exceeds that of door blocks made of other materials.

Aluminum doors are highly resistant to fire; their design does not ignite or explode. These products do not require regular maintenance using special means. This greatly simplifies the process of their operation. In addition, products made from aluminum profiles do not cause harm environment, and also do not provide negative influence on human and domestic animal health. It should also be noted that the special coating of the profile allows you to avoid corrosion even in aggressive environment. In addition, the weight of aluminum doors is small compared to wooden or metal-plastic counterparts. The surface of the products is covered with paints and varnishes of any color and texture.

Technical requirements for aluminum doors

Aluminum doors are manufactured in accordance with the provisions of GOST, which since 1995 has been revised, supplemented and published again in a new edition every five years. In addition, in the process of manufacturing doors, it is necessary to follow the requirements of regulatory and technical documentation for products of a specific type, as well as working drawings.

Characteristics of aluminum doors

GOST number 23747-88 stipulates that aluminum doors must have high strength and stability during transportation, installation and operation. In addition, such doors must withstand at least 100 thousand cycles of opening and closing the doors. Along with this, it is imperative to cover them with paint and varnish compounds during the production of aluminum doors. This finish performs protective and decorative functions. It would be useful to say that it is prohibited to cover the product in the assembled state, since this is contrary to GOST standards.

Another requirement state standard is mandatory equipment aluminum doors with full glazing and protective grilles. These measures are taken to prevent mechanical damage glass This standard applies to those structures that are not equipped with automatic opening and are installed in places with large crowds of people. These include, for example, train stations, metro stations, and airports. It is also stipulated that the design of such aluminum doors should exclude the possibility of arbitrary dismantling of the doors and locking mechanisms.

Materials and other elements of aluminum doors

Door frames are also produced in accordance with the provisions of GOST number 22233-83, which sets standards for profiles made of aluminum alloys. Other structural elements, as well as mounting bolts, nuts, screws and washers, are made of carbon steel coated with cadmium or zinc based compounds. Glass inserts for the door leaf are made from glass or double-glazed windows. Wherein minimum thickness the first should be 5-6 mm, and the second 15-28 mm.

Aluminum sheets or extruded profiles are used as light-blocking inserts. In addition, you can use other materials, but with a thickness of at least 5-6 mm. Seals are made from light- and frost-resistant rubber or plastic.

Aluminum door components and storage conditions

Products may be supplied disassembled. It means that fasteners and accessories, as well as optional equipment do not necessarily have to be installed into the structure in production. They can be delivered separately complete with a frame and installed on site. The manufacturer's mark, as well as the brand, date of manufacture and stamp are placed on the reverse side of the product. It should be noted that for long-term subsequent operation, finished structures must be stored in rooms with a functioning ventilation system.

Stow finished products required for wooden pallets, and between several samples laid vertically in a row, it is required to place wooden linings. It should also be noted that in places where aluminum doors come into contact with brick, concrete or plaster, the contact areas must be coated with an anti-corrosion compound.

Conclusion

It should be noted that today most manufacturers of aluminum door blocks in the process of their manufacture follow their own technological standards, which to one degree or another comply with GOST 22233-83.

4.5.6 The appearance of the coating must comply with GOST 9.301.

4.6 Requirements for filling door panels and sealing gaskets

4.6.1 It is recommended to make the opaque filling of door block panels (panels) from three-layer panels consisting of plastic or aluminum facing sheets filled with insulation or single-layer panels of rigid foamed polyvinyl chloride. The thickness of the facing sheets must be at least 15 mm

It is allowed to use sheet, roll or tile facing materials as panels for interior door blocks.

4.6.2 Design solutions for fastening parts of filling parts of locking door leaves must exclude the possibility of their dismantling from the outside.

4.6.3 It is recommended to use the following types of strengthened glass as a translucent filling of canvases: tempered glass in accordance with GOST 30698, laminated glass in accordance with GOST 30826. reinforced glass and glass with anti-fragmentation films in accordance with regulatory documents, double-glazed windows in accordance with GOST 24866. sheet glass according to GOST 111. as well as special types of glass according to regulatory documents (patterned, tinted, etc.).

The types of glass used should be specified in the working documentation for the construction (reconstruction, repair) of buildings and structures. Use of non-strengthened glass with height dimensions greater than 1250 mm. a width of more than 650 mm and a thickness of less than 4 mm is not allowed.

4.6.4 To increase architectural expressiveness and strengthen the structure, frames are installed in the door leaf frames. It is allowed to use double-glazed windows with an internal decorative frame or install glued decorative layouts on the outer surfaces of the filling of the canvases.

4.6.5 The depth of pinching of a double glazed unit (glass) or panel in the folds of profiles, as well as the depth of pinching with glazing beads, is recommended within 14-18 mm.

4.6.6 Double-glazed windows (glass) are installed in the rebate of the sash or frame on pads that prevent the edges of the double-glazed window (glass) from touching the internal surfaces of the profile folds.

Depending on the functional purpose, the linings are divided into basic, supporting

and remote.

Base shims are used to level the rebate bevels and are installed under the support and spacer shims. The width of the base pads must be equal to the width of the rebate, and the length must be no less than the length of the support and spacer pads. Support and spacer pads can combine the functions of basic pads.

Support pads are used to ensure optimal conditions for transferring the mass of the glass unit to the door block structure, spacer pads are used to ensure the nominal dimensions of the gap between the edge of the glass unit and the fold of the sash.

The length of the support and spacer pads should be from 80 to 100 mm. width - at least 2 mm greater than the thickness of the glass unit.

The distance from the pads to the corners should be 50-80 mm.

Requirements for the installation of opaque filling of panels (panels) are established in the manufacturer’s technical documentation, taking into account the weight and design of the door block.

4.6.7 Linings are made of rigid weather-resistant polymer materials. The recommended hardness value of the support pads is 75-90 units. according to Shore A.

4.6.8 Installation methods and (or) design of the linings must exclude the possibility of their displacement during transportation and operation of door blocks.

4.6.9 The design of the linings should not impede air circulation over the inner surface of the glazing rebate.

4.6.10 The basic layout of support and spacer pads when installing double-glazed windows, depending on the method of opening the door blocks, is shown in Figure 1. It is recommended to install no more than two support pads on any side of the glass unit. Distortion of the pads during installation is not allowed. In products with reinforced locking devices, it is recommended to install additional spacers in the locking areas.

4.6.11 Sealing of the door panels and installation of filling of the panels is carried out using sealing gaskets made of elastomeric materials in accordance with GOST 30778 or other regulatory documents.

4.6.12 Sealing gaskets for external door blocks must be resistant to climatic and atmospheric influences.

4.6.13 The fit of the sealing gaskets must be tight, preventing the penetration of water.

4.6.14 The number of contours of sealing gaskets in the rebates of door blocks and the requirements for their installation along the perimeter of the rebate are established in the manufacturer’s technical documentation, depending on the purpose and design of the door blocks. For door blocks of groups A and B, at least two sealing circuits are recommended.

Corner bends and welded joints of sealing gaskets for double-glazed units (glasses) should not have protrusions (bulges) that cause concentrated loads on the double-glazed units (glasses).
