Sizes of entrance metal doors with a box

Modern technology allows you to create a variety of shapes, sizes and protective characteristics of the entrance doors made of metal. Steel is one of the most popular materials for a range of iron models. It guarantees strength, rigidity of the structure, but requires exact correspondence between the parameters of the canvas and the box, the box and the doorway.

In the first case, to eliminate installation errors, avoid inconvenience in operation, manufacturers take responsibility for themselves, making the whole set. It includes:

• the box is from the corner of a closed rectangular or U-shaped form (the threshold is ready or made separately), its components: crossbar, guides;

• door leaf of steel sheets welded together;

• amplifiers - “stiffeners”: longitudinal, transverse, or V shapes (sometimes a combination of them) that increase the strength of the web and prevent its surface from being deformed;

• inner lining;

• exterior facade finish made of various decorative materials;

• a seal located between the web and the skin to increase thermal protection;

• fastening systems - loops: open, hidden, equipped with anti-burglary systems;

• platbands;

• additional elements: locks, latches, door peephole, handles, seals.

The correct ratio of the sizes of the box and the opening can be guaranteed only by well-performed measurements, as well as further careful selection of the design. The measurements can be performed by representatives of a specialized company, as well as by the customer. To do this, it is necessary to study existing regulations. All linear values ​​of the entrance doors are interrelated, defined by SNIPs and GOST standards, under which the dimensions of non-standard models are often customized.

On the linear dimensions of the design of the input unit affect the technical requirements for the operation of premises. Therefore, the street doors in the country house will always be wider than in the apartment. The openings facing the landings and vestibules should not be the width of the flight of stairs.It is convenient for moving dimensional furniture, evacuating during emergencies.

The sizes of entrance iron blocks conforming to fire-prevention requirements of Construction Norms and Regulations 210197:

• height - not less than 1900 mm;
• width for residential buildings - from 800 mm, for public (more than 15 people) - from 1200 mm.

The main parameters of the standard block sizes of input metal doors are in the range (in mm):

• the height of the box - from 2070 to 2370.

• The width of the door or light opening for a dwelling:

1. For single doors - from 800 to 1000,

2. For one and a half, from 1300 to 1500,

3. For bivalves - from 1910 to 1950,

• The thickness of the block (the door with the box):

1. With a brick wall 75 mm - 108;

2. With a standard wooden bar - no more than 120,

3. In panel houses - 120-130.

Compliance with standards ensures durability, convenience, durability of metal products.

Options for ready-made solutions for door units:

1. For single-leaf (in mm) - 1980x850, 2030x860, 2050x880, 2050x960, 2070x900, 2100x950, 2100x1000. Blocks of small size can be used in extensions.The optimal combination of the size of the input metal doors and boxes is 2500x900.
2. For bivalves (in mm) - 2050x1300, 2100x1400, 2100x1500, 2100x1600. With a height of 2000-2300 standard width (in mm):

• 1,200 (600 and 600);
• 1600 (800 and 800);
• 1800 (900 and 900).

In Russia, the door leaf is of two types - from welded sheets mounted on the frame, and solid, more durable.

The final thickness of the working surface of the product depends on the number of interconnected steel sheets, corresponds to:

• for apartments - from 1.5 to 2 mm;
• for country houses - 2-2.3 mm.

Thin cloths are used if the house has a vestibule.

In all other cases, the standard thickness of the entire door is:

• for ordinary models - from 60 to 80 mm;
• for reinforced - from 80 to 100 mm.

The total value is formed due to additional structural elements:

1. Cameras for insulation. It is necessary for residential buildings, because through the usual door is lost up to 25% of the heat. Depending on the material used by the manufacturer and the number of its layers, the parameters of the required internal space are formed.
2. Sealing contour. It is used for better tightness, which contributes to the preservation of heat and the obstruction of extraneous odors from the entrance. Depending on the thickness of the iron doors, 2 or 3 circuits are installed. The design with three seal contours corresponds to a door thickness of 80 mm.

Sometimes you have to make a choice between the level of protection and the beauty of the door: any reinforcement, additional finishing entail an increase in its weight, which should not exceed 250 kg. The limiting values ​​of the thickness of the canvas normal and all reinforced models weigh over 200 kg already.

Doors that do not coincide in shape, thickness, height, decorative solution (glass inserts) and the number of reinforcements with average values ​​of the norm are considered to be non-standard. The permissible parameters of such models are enshrined in separate articles of GOST and SNIP.

• Blocks with side and upper transomscustom made. The width of their working passage corresponds to a single or double door, the steel reinforcement of the central structure begins 120 mm from the edge of the opening.Typical dimensions of a single arched door are 2000x800 mm.

• One and half doors - The narrow sash closes and opens as needed. With a height of 2000 or 2300 mm width is (in mm):

1. 1200 (400 - stationary sash, 800 - working canvas or 300 and 900);
2. 1,400 (600 and 800 or 500 and 900).

• For non-standard doors also include fire and armored doors:

1. The thickness of the fire - 70 mm, armored - 100-120 mm;
2. The dimensions (in mm) are 1200x1900, 1200X2050, 2500x2500.

Non-standard entrance openings in apartment buildings must be approved by the BTI. The decision will largely depend on the thickness of the walls of the house, on which floor redevelopment is planned. In a private building, where we can talk about the supporting structures of the house, you will need to order the project in a specialized organization.

Today, under the common name of the iron door hides several types, including multi-chamber models. These include:

1. Metal-plastic - has a strong protection system, fairly light in weight, comes with glass units of various sizes and sizes.When the profile is reinforced, such doors are installed in “thermos houses”.
2. Aluminum - the lightest of all metal, with or without double-glazed windows. Heat protection is high, increased wear resistance. 7 times stronger than wood, 2 times more metal-plastic products.

Difficult calculations of the box and the canvas are not made, technology allows the manufacture of blocks of any size and immediately in the kit. They differ from steel structures only in thickness - 95-120 mm. The more voluminous the metal profile, the warmer. Due to the lightness of the material, even with limiting values, additional loops are not required.

In the cottages, the entrance blocks are completed with a pressure set, a lock along the contour, which guarantees a tight fit, with a threshold of aluminum - 40 mm. In the double doors can be used shtolpovy connection.

European models attract Russian buyers with their design and relative ease of construction. For their production using lighter steel.The dimensions comply with DIN regulatory requirements, which are guided by the architectural traditions of Europe and are based on anthropometric data of individual regions. Based on these, people in Finland are higher than in the south of the EU, so the Finns will have a standard entry height higher than in Italy.

There are differences among countries in width. French standard for single door doors (in mm): 690, 790, 890, 990. Spanish standard (in mm): 600, 700, 800, 900, 1000.

Imported products require additional expenses:

• when modifying a block, when an imported canvas is installed in the domestic box;
• when reducing or increasing the input opening.

The warranty period for products is much higher than that of Russian - up to 10-20 years, but overseas manufacturers cannot ensure the fulfillment of obligations outside the European Union.

Furniture companies operating in Russia or for a long time, not less than 5 years, trading in the local market take into account differences in standards, offering ready-made solutions to eliminate inconveniences. Some manufacturers make batches according to the standards of the Russian Federation.

The Chinese models in their parameters coincide with the national standards.

Supplied models have:

• on height - 2050 mm;
• single-leaf width - 860, 960 mm, one and a half - 1200 mm.
• in different batches of even one manufacturer, the size of the doorframes can have a significant difference and vary from one delivery to another. Trust is caused by joint Russian-Chinese manufactures, where all products undergo quality testing according to RF standards.

Before taking measurements, it is necessary to dismantle old doors, including door trim. If necessary, remove the threshold.

Rigid metal structures need smooth walls, so the degree of curvature of the walls is determined using a level. In the case of a large curvature, the entrance metal door with the box is aligned to the standard size with regard to technical clearances. The same actions are made with the threshold.

After that, the tape measure length, width and depth of the opening. The values ​​of width and length are removed from the base of the wall, the results obtained are compared with the reference ones. The clearances are checked.

There are technical gaps between the opening, the box and the canvas. They are necessary to easily install the unit, to ensure the door free running.

When calculating the door unit, this free space is not taken into account, but its presence is implied:

• The inner perimeter of the box is larger than the outer perimeter of the main structure of the door (without taking into account the influx) due to gaps:

1. In the upper part - 3-5 mm;

2. In the lower part - 6-8 mm;

3. In width - from 3 to 6 mm to each side.

The height of the door unit = width of the angle or pipe (30-35 mm) x 2 + door height + gaps.

Door block width = angle width x 2 + door width + gaps.

• The entrance should be larger than the door frame on each side:

1. In height - no more than 5 mm at the narrowest point of the opening,

2. In width - 2 mm.

The parameters of the door unit depend on the input opening. Its size, in turn, depends on the project of the building and must be in harmony with other values: the height of the walls, the space on both sides of it.Aesthetic ratio of sizes is especially important to consider when designing country houses. The error threatens with inevitable redevelopment.

Modern equipment makes it possible to produce canvases and boxes of any configuration with the most sophisticated design solution. You can allow arched forms with stained glass inserts on the transom, decorated with forging, or tricuspid blocks with a complex combination of metal and glass. A must-have addition is a visor that will reduce the impact of an aggressive environment on the canvas and will allow to prolong its service life.

In apartment buildings there are no problems with matching different values. However, new architectural trends sometimes create problems: the size of the openings may not be suitable for standard sizes of door blocks.

Series P-44T - most often found in Moscow. The size of its doorway is 800x2000 mm. A very small passage that needs to be expanded at least to install the 860x2050 block. To do this, it is necessary to remove excess walls from three sides. A comfortable width of 960 mm requires expansion of the space to 1000 +/- 10 mm. Large furniture in smaller openings bringing into the apartment will be problematic.

Series home P-111M (111-M). The size of the doorway is 2100x900 and 2100x1000 mm.

Installation occurs without problems. Suitable dimensions of the door frames are 2050x860 mm or 2050x960 mm, but before ordering, it is better to take measurements, clarify the numbers.

Series home P-55M, P-30M, P-3M. The size of the opening - 2070x900 mm. The required box sizes are 2030x860.

Under normal operating conditions, the base of the steel door can last up to 100 years. Finishing, depending on the materials used, may require renewal after 10-25 years. The warranty on locks is no more than 2-5 years, but this is more likely a reinsurance from the manufacturers.
