Metal entrance doors: how to choose?

A reliable front door is a guarantee of security in the house and the safety of property. The undisputed leader among all options available on the market is metal entrance doors. It is a combination of steel and style that guarantees the protection of the home and testifies to the good taste of its owners..

Peculiarities

Entrance metal doors that are optimal in all respects are characterized by the following features:

  • Closed production cycle. If all the elements for assembly are made at the same factory using high-tech equipment, they fit together perfectly, and the design has no flaws. In addition, closed production is present only among reliable companies that pay maximum attention to the quality of the goods produced and it is almost impossible to counterfeit them. The exception is the use of door locks in the configuration from firms specializing only in their production..
  • Availability of all necessary certificates for products.
  • High level of noise isolation. Metal doors cope with this task many times better than others, since the thickness of the door leaf is greater, and the hollow space inside makes it possible to use a high-quality interlayer that drowns out unnecessary sounds. Also, only multi-chamber double-glazed windows cope well with sound insulation..

  • High-quality thermal insulation. Doors with good insulation are an insurmountable barrier to freezing temperatures and do not allow heat to escape outside.
  • High quality seal not only contributes to maintaining a comfortable indoor temperature and absorbing sounds, but also prevents them from entering the house
  • foreign odors.
  • Metal sheets are more resistant to fires, than wood or paste.
  • Bank-grade security. The metal sheet protects the house like a safe with jewelry, to which it is impossible to pick up the key. And a specially planned structure increases the level of burglary resistance.
  • Stiffening ribs are located inside the door leaf, the special shape of which provides additional protection against cutting and drilling.

  • Product availability for any wallet. Of course, for any manufacturer, the price range varies from economy to premium class, but a reliable door without design delights will cost less than 15,000 rubles.
  • With regard to design possibilities, all standard models are distinguished by laconic elegance., and the model for individual development is limited only by the financial capabilities and imagination of the customer, since a huge number of different materials and their combinations are used in production. The outer finish of the door can remain metal, have forged parts, glass and mirror inserts, bright color, airbrushing, can be finished with plastic or wood. Wood veneer, in turn, is laminated, painted, subjected to various processing technologies, including brushing (aging). Available in milling, laser cutting, forging, hand painting, colored film and even stained glass. Whether the dominant style is historical, modern or eclectic, the metal front door is successfully integrated into it.
  • The warranty period of the product is at least 5 years. The real service life exceeds this figure by 3-5 times..
  • “Correct” filling is equipped with good fittings: locks, hinges, door peepholes, latches, and other important little things help to increase the burglary resistance of the product to give it a more presentable appearance.

  • Metal entrance doors are suitable for non-standard openings, whether it is a single-leaf, one-and-a-half or double-leaf door, arched rectangular or square in shape.
  • The door from the side of the street in a private house must be treated with a special solution. This coating protects it from moisture, atmospheric pressure drops, corrosion, direct sunlight, fading.
  • A good metal door has a solid frame and wide platbands that protect the anchors from attempts to saw through them.
  • If necessary, you can choose an armored front door.
  • GOST the production of entrance metal doors is strictly observed.

What does GOST include?

The state standard regulates production standards and guarantees the right of everyone to purchase quality goods. The structure of a metal door (steel, iron or aluminum) consists of a door frame, metal and decorative platbands, a frame, stiffeners, an iron sheet 3 mm thick, a filler (mineral wool, fiberboard, polystyrene, wooden beams), a sealant, an additional sheet of steel or iron in the area of ​​the lock (only 6mm), external panel, protection for hinges and crossbars, fittings.

Door leaves are made of steel or aluminum profiles, welding is permissible with the obligatory indication of the welding points in the accompanying documents. Stiffeners or profiles and insulation made of environmentally friendly, non-toxic materials are required between the sheets.

Also, for heat and sound insulation and protection from odors, a seal from two circuits or more should be installed on the door. It provides maximum tightness. The inner door leaf can be welded from lump metal or replaced with fiberboard plates and other material of appropriate strength.

Locks and fittings are subject to separate standards. They prescribe the installation of a “window” on the inside for easy replacement of the mechanism and prohibit welding the lock in order to avoid damage to small parts by high temperatures. The lock bolt must be at least 22 mm deep inside the door frame. According to GOST, all doors are divided into classes 1,2,3 in terms of air, water, sound, heat insulation and burglary resistance, where M1 is the highest protection class. The standard also regulates the dimensions of doors in accordance with openings in typical residential buildings, strength test methods and requirements for correct installation..

Types of material

The front door not only protects from uninvited guests, but also performs other functions that provide peace, silence and comfort to the inhabitants of the house. At the same time, it is an integral part of the interior from the inside, and the “clothes” by which the owners of the house are judged from the outside, therefore the materials of manufacture play a huge role, regardless of whether they are visible to the eye or not. The door can be conditionally divided into four layers, each of which is responsible for a practical or aesthetic function: door frame, interior filling, interior decoration and exterior decoration.

Frame

Metal doors are a generalized concept, since different types of metal are used in their manufacture: aluminum, iron, steel, various alloys. A door made of an aluminum profile serves well as an external door due to the resistance of aluminum to corrosion. It provides effective thermal insulation without freezing, protects well against extraneous noise, does not require painting or renewal of the protective layer. But aluminum itself is quite soft, and without additional reinforcement, such a profile does not have a high level of burglary resistance, but this metal costs more than iron or steel.

The iron door was at the peak of its popularity when the trend of replacing standard wooden doors with more reliable ones emerged. Over time, various alternatives have emerged, and iron has moved into the class of the most economical options. In addition to being cheap, such canvases have practically no advantages. The metal is easily deformed, has no stiffeners, is subject to corrosion, and the sheet thickness does not exceed two millimeters. There is no additional protection around the locking device either, so it makes no sense to try to reanimate such a door by installing several reliable locks on it..

It is important to take into account that in its pure form, iron is used only for laboratory purposes, and it comes into production with various impurities. In this case, metal alloys may be the best option, but their composition often remains unknown, and without an exact indication of the components and their percentage, it is difficult to say how reliable such a door will be..

The most effective of the known alloys is the combination of iron with carbon (it deprives iron of its toughness, making it strong and hard) and alloying elements (optimizes the properties of the metal in accordance with the operating conditions). The more common name is steel. Steel entrance doors are available in hot rolled (less durable) and cold rolled (harder) steel. The second type is more often used in the production of door leaves, since it makes it possible to produce thin, but reliable protection.

Advantages of steel entrance doors:

  • Strength. It can only be cut with a grinder, but it is completely impossible to knock it out;
  • Long service life. The steel sheet retains its original appearance for decades;
  • Resistance to mechanical damage, which cannot be said about the aluminum profile;
  • Additional protection in the form of crossbars and linings;
  • High-quality heat and sound insulation;
  • Large number of finishes.

There are also drawbacks to such doors. If you have a complex design or a beautiful finish, the price is much higher than the standard one. The thickness and density of materials add up to a large weight of the product, which not every masonry can withstand. It is simply impossible to mount steel doors in some types of materials. It will also not work to carry out the installation alone, you will need the help of professionals.

Filler

The internal filling of the metal profile does not in any way affect its burglary resistance, but it is responsible for such important functions as heat preservation, frost protection, a barrier against extraneous sounds, fire safety.

Common types of filler are divided into materials of economy class, middle price category and premium segment..

Economy includes:

  • Honeycomb corrugated board. Lightweight multi-layer cellular filling, characterized by rigidity and good soundproofing properties. It also helps to keep the room warm, but does not cope with moisture resistance;
  • Synthetic fiber. Soft and lightweight filling material that has poor heat dissipation, but does not protect against noise and moisture;
  • Foam rubber. It has unique insulating properties at a low cost, but it can shrink, therefore, stiffeners must be provided in the door structure. Foam rubber can suffer from condensation (moisture) between door leaves.

The middle category consists of:

  • Izolona. Self-adhesive roll material that needs to be combined with other materials;
  • Styrofoam. Not suitable for external doors in a private house, but in the vestibule and on the staircase, you can safely use doors with such a layer for high-quality insulation of noise, moisture and heat;
  • Polyurethane foam plates. It is distinguished by high performance, durability, ease of installation, lightness. Best in its segment.

The premium class includes:

  • Rigid polyurethane foam. It has a porous texture, due to which it perfectly copes with the tasks set, however, it requires a frame of stiffeners due to the tendency to shrinkage;
  • Mineral wool. Better than any other material, it retains warmth, silence and provides comfort to residents. One of the few is environmentally friendly and does not emit toxins.

External and internal finishing

The appearance of the door is the status of the dwelling. Much depends on whether it is external (at the entrance to a private premises, at the “street-house” border) or internal (installed at the entrance to the apartment), since the external doors have a large atmospheric load.

Exterior finishing options:

  • Powder spraying. This is a universal coating that provides an aesthetic appearance of the door, protection of the door leaf from mechanical damage, resistance to alkaline solutions, temperature extremes (from -60 to +130), aggressive effects of the atmosphere, humidity, corrosion, fire;

  • Laminate. This material is used both as exterior cladding and interior decoration. It gives a smooth, beautiful, original coating, which increases the insulating properties of the door, is shock-resistant and wear-resistant, poorly prone to dirt, and does not fade. However, laminate flooring is only suitable for doors to an apartment, since it is afraid of moisture and does not tolerate wet cleaning with the use of aggressive household chemicals;

  • Veneer. A completely wooden front door, of course, looks expensive and beautiful, but its cost is corresponding with a relatively worse burglary resistance. The use of natural veneer (thin sheets of wood), which retains the pattern and texture of the wood, allows you to combine the aesthetics of natural materials and the reliability of steel doors. This finish will add elegance to the door and reliably disguise its steel “filling”. The wood layer plays an important role in ensuring the comfort of the inhabitants of the house and increasing the wear resistance of the metal structure..

  • MDF panels. Modern production technologies have made great strides forward, so not everyone can distinguish veneer from pressed wood shavings, but this material costs several times cheaper, while the effect is the same. The only condition that must be observed when working with MDF overlays is to protect the panels from water;

  • Lining. Lining is often called a type of MDF, but their main difference is that these narrow, carefully processed and perfectly fitted boards are cut from solid wood, and not pressed from the product of its processing – sawdust. It can be smooth or textured, light or dark, with a special impregnation against putrefactive fungi and a protective coating, which makes the lining a universal material for the exterior decoration of an entrance metal door;

  • Euro lining. The main difference from ordinary lining is the drying method – artificially in chambers, and not natural. Additionally, the lining is impregnated with compounds from fungus, mold, insects, high humidity, burnout under the sun;

  • PVC film. This two-layer material (adhesive base and decorative coating) is very easy to use, protects the metal door from moisture and corrosion, is easy to clean, affordable, durable and odorless. At first glance, it is practically indistinguishable from veneer due to the realistic pattern on the surface. The film is easy to clean, does not fade, and the polyester coating protects it from damage;

  • Painting. The most inexpensive material that does not increase the insulating properties, but works on the aesthetics of the appearance, protects the metal from moisture, chemical attack, corrosion and allows you to create a unique door design. With the help of paint, you can give the canvas any shade, and the even distribution of the substance when using spray cans or an airbrush gives a perfectly smooth surface without streaks and brush marks. You can also use stencils to apply an interesting pattern, and people with great artistic talent can embody even complex airbrushing. So the most budgetary steel door without decor will turn into a home decoration;

  • Decorative materials. Forged glass, mirrors, mosaics, stained glass – all this can be used for exterior door decoration without compromising its performance.

When choosing materials for decoration, it is important to remember that the door should be in harmony with the wall decoration, be it paint, plaster, brick or panels, and be suitable for certain climatic conditions.

Fittings are an integral part of the decoration. It must be reliable and match the style of the entire structure. This mainly applies to door handles, which today can be found in any convenient option, from wood and plastic to metal in various colors, with or without decor. Interior decoration is an integral element of the interior interior, therefore, it must match the design in color, material and style. Strictly speaking, the inside of the door can be completely finished without finishing, since a solid sheet of steel is quite consistent with some industrial trends, in which raw and rough materials are only welcome. For example, for a loft or grunge with their brick, concrete and plaster walls, it may well be left unheated..

However, not all styles are so unpretentious. The arsenal of materials for interior decoration of a metal entrance door includes:

  • Solid wood. It is the most expensive, durable and environmentally friendly material. It is indispensable in luxurious interiors and in environments with emphasized harmony with nature. Wood is very malleable in processing. When using it, carving, painting, varnishing, inlaying, various methods of processing with solutions are available. The most popular method is brushing (artificial aging), which allows you to turn cost-effective furniture wood (birch, pine, oak) into aged wood of precious species (mahogany, wenge, mahogany);

  • Finishing materials based on natural wood: veneer, laminate, MDF and chipboard. As with outdoor decoration, these materials are suitable for indoor use. At the same time, veneer and laminate can be classified as premium materials, and MDF and chipboard are budget solutions;

  • Natural and artificial stone. This is an expensive and sometimes inappropriate pleasure. Finishing with thin slabs or plates of stone (more often artificial) is necessary to maintain an interior in which such elements are already present. When choosing this material, it is important to take into account that it will increase the weight of an already heavy metal door, so the hinges, frame and walls must be designed for such a load. In most cases, it is wiser to do with high-quality plastic panels or a self-adhesive film that imitates the texture of a stone in a pattern;

  • Mirror and glass surfaces. Mirror, glass and other reflective surfaces are used in the design of a room to give it airiness and visually enlarge the space. Modern technologies allow you to choose safe mirrors and glasses, which are made on the principle of triplex double-glazed windows. Triplexes are difficult to break, and if this happens, they do not fall apart – all the fragments remain inside the strong film that covers the outside of the glass. You can decorate the mirror with a sandblast pattern or a film for stained glass;
  • Powder spraying. An affordable and durable finish that allows you to experiment with color;

  • Artificial leather: eco leather, leatherette, dermantin, vinyl leather. An inexpensive and widespread type of coating, which in a modest gray, brown, green color is appropriate in a “grandmother’s” interior, and in a bright shade of pomegranate, fuchsia or azure, it will ideally complement fusion, kitsch, pop art, contemporary art, and many others styles. It is important to use a carriage coupler on a dermantine, as on leather furniture;

  • Plastic. This material is used either in order to save money, or, if necessary, to beat the interior with it, or as a replacement for more expensive materials. Plastic panels are easy to use and unpretentious, but they are easily scratched and do not belong to environmentally friendly materials;

  • Wallpaper. A rare type of decoration required to create an optical illusion of a background receding into the distance, drawings with a perspective, visually expanding the space. They can also replace, for example, stone, fabrics and airbrushing.

Models

The classification is made according to several criteria:

By appointment

Outdoor (street), indoor (apartment), vestibule, front, office, technical, specialized. External doors are installed at the entrance to a private house and are distinguished by the presence of protective and anti-vandal coatings. It is better to choose those materials that do not darken, do not fade, are resistant to high humidity and low temperatures..

Internal doors or doors to the apartment are mounted at the entrance to the premises from the staircase. Since they are not exposed to the negative influences of the environment, they do not need an increased degree of protection, as for the street, but anti-vandal protection will not hurt. For greater comfort and tranquility, double doors are installed. In this case, the second does not have to be made of several layers of steel and with a complex burglar protection system. An aluminum profile, an iron door or even a wooden one is enough. This will allow you not to make the structure heavier and give the inner side of the doors a more aesthetic appearance..

For additional protection of the common site with neighbors, vestibule doors are installed. This is an additional security measure, but not too reliable, since in order to save money, as a rule, iron doors with a low level of burglary resistance are chosen. Tambour doors can be replaced with technical ones, and vice versa. Office and front doors differ from ordinary entrance doors only in appearance. They refer to the entrance loops to administrative buildings or offices of private companies, and the main requirement for them is to reflect the prestige and status of the institution. They often have non-standard elements, complex decor and individual design, several doors.

Specialized doors include all the advantages of conventional doors (warm, soundproofed, moisture resistant), as well as their design implies modifications that take into account the peculiarities of operation. They can be fireproof, bulletproof, with a thermal break (for very low temperatures), with a ventilation grill with a bulletproof eye, and others. Some of them are not produced in series, but in single copies. The changes include doors with a window, with a window and forging.

By technical characteristics: design features and opening method

The basic configuration includes all the elements recommended by GOST, but the doors are often subjected to all sorts of improvements for different operating conditions: additional layers of the seal, reinforcement of the profile, protection of the hinges, strengthening of the locking mechanism, special coatings for external and internal finishing (from moisture dust, animal claws , UV rays and other threats to the quality of appearance). The changes introduced may also affect the shape of the door. In addition to rectangular, there are also square and arched models..

Also, the technical characteristics include the number of door leaves. Common options are single-leaf (one door leaf) and double-leaf (two leaf). The bipartite, in turn, can be of different types – with different widths and with equal valves. The accordion door is a rare occurrence. It looks beautiful, but it is not very comfortable in metal design, since there are few objects in which it would be appropriate and necessary. The “accordion” consists of three or more parts-sashes, connected by hinges.

The design features determine the type of door opening. There are four options: right-sided inward, right-sided outward, left-sided inward, left-sided outward. For double doors, both leaves or only one can open, then the second must be locked in place. Folding doors – sliding. Due to the design features for metal entrance doors, it is recommended to choose an external opening. According to the class of resistance to attempts to penetrate and break-in, there is a state standard and individual manufacturer’s standards. The highest grade is the fourth.

Dimensions (edit)

The standards for the dimensions of door leaves are set by the dimensions of typical apartment buildings. The most common types of metal entrance doors in all price segments are models 980×2050, 980×2100 and 880×2050 mm. However, single-door doors do not always match the size of the doorway. In this case, one-and-a-half models will help out, the dimensions of which are in the range of 1010-1550 mm in width and 2050-2370 mm in height..

For the largest openings, double doors are required. They have impressive overall dimensions: 1910-1950 by 2370-2450 mm. The thickness of the door depends on its “filling” and has no strict regulation. This is the thickness of the metal plus the frame, seal, cladding and decor. The metal “interlayer” in the entrance doors can be single-layer, two-layer or, in exceptional cases, three-layer. Average thickness of one sheet – not less than 2 mm.

Color solutions

A widespread and familiar phenomenon is metal doors in brown, chocolate and graphite colors. These practical shades are usually obtained using powder coating, which makes it possible to choose a more colorful option: red, silver, burgundy, garnet, emerald, blue. Even rare colors like mustard and Prussian blue are available. Such simple doors are not suitable for any type of wall decoration. Some options for cladding metal doors have their own characteristics, including the color palette. This applies to wood finishing and wood processing products..

“Pure” wood is capable of giving white shades from warm to cold (bleached oak, pallada oak, birch, pine), a light palette (all gradations of walnut, beech, Karelian birch, teak), noble dark tones (mahogany, ebony, brushed oak, cherry, wenge, mahogany, mahogany). Great possibilities for design are opened by the use of plastic panels for cladding and color film, painting (including drawing by airbrushing).

How to choose?

The choice of a metal door is a responsible business and requires some knowledge about the design features.. For those who want to choose a reliable and high-quality door, it is recommended to take advantage of the advice of professionals in the field of repair and design:

  • It is important to correctly assess the operating conditions. Of course, mahogany trim looks elegant, expensive and beautiful, but how many years it will be able to maintain its impeccable appearance in conditions of constant dampness and atmospheric influences is a big question. Even the best impregnation does not guarantee protection against darkening, cracking and decay, but powder coating, glass and forging perfectly withstand temperature drops and harsh weather conditions.

  • Take into account both the weight of the product and the thickness of the walls into which the door frame will be mounted. Not all materials are capable of withstanding heavy loads. They can begin to crumble, crack, and it will not be difficult to “plant” a door sitting in such an opening. The maximum permissible weight of a metal entrance door is a quarter of a ton, and this must be taken into account when choosing a product by weight.

  • Before buying a door, you must measure the doorway at least at two points in height and width..

When choosing, pay attention to:

  • The quality of the door frame (frame). The opinion that the reliability of the structure depends only on the thickness of the door leaf is erroneous. With a poor-quality and weak box, the degree of protection is significantly reduced;
  • Metal type, from which the sheets, frame and platbands are made. In terms of reliability, aluminum is better than iron, and steel is better than aluminum. It is also important that the steel sheets are at least 2 mm thick and are made from cold rolled steel;
  • Filler type. The best, albeit the most expensive, option is mineral slab or mineral wool. In the cheaper segment – polyurethane foam;

  • Type of exterior and interior decoration. The external one should be protected from damage and the influence of the environment, and for the internal it is better to choose natural and environmentally friendly materials;
  • Door thickness. This is a fundamentally important factor, since several layers of steel, stiffening ribs and good filling, on which safety and insulation depend, cannot add up to a thin door leaf. The thicker the door, the better its performance;
  • Door opening method;
  • Hardware quality and how it is secured. Sharp corners, looseness, cheap appearance are signs of a poor-quality product;
  • Locking device type. The best option is a combination of two locks of different types and additional reinforcement of the structure with crossbars;
  • Availability of quality certificates. Studying the technical data sheet of the product will save financial and time costs for repairs in the future.

  • The best doors are time-tested. If you are not sure of the choice, you should turn to the products of manufacturers that have established themselves in the market and have been tested by many buyers..

Manufacturers overview

Among the leaders in the production of affordable and durable metal entrance doors are Chinese, German, Italian manufacturers. There are also several representatives of the CIS countries, including Belarusian and Russian firms. In recent years, China has begun to destroy stereotypes about illiquid consumer goods. According to user reviews, you should pay attention to the LS brand and other companies that do not use corrugated cardboard as insulation.

Among German firms, the doors of Hörmann are worthy of attention, in Italy the best are Dierre and Leganza, in Russia – “Gardian”, “Torex”, “Le Grand”.

Beautiful examples in the interior

Metal entrance doors are a versatile solution for apartments and houses. Thanks to a wide range of materials, the exterior finish will match the finish of the whole house and the design from the outside and from the inside, whether it is an economy class product or luxury doors. Veneered doors integrate beautifully into interiors with the presence of wood, plastic and paint – into interiors with siding panels, glass, forging, metal decor and stained glass – a great addition to masonry and brickwork.
