Often during repairs in an apartment or after moving to a new home, the question arises of replacing the door with a better and more durable one. As practice shows, the door must be made of steel sheet. But regarding other parameters and details, it is often required to consult with professionals. Let's find out how to choose a door and consider the rating of the best metal doors for an apartment.

The safety of metal doors is affected by the thickness of its base, the outer sheet of steel, as well as the presence of stiffeners in the structure. At first it seems obvious that these parameters should be as large as possible. But on the other hand, this increases the mass of the door, as a result of which the hinges will wear out faster due to the high inertia.
Any quality door should have a few basic elements. The frame should be made of a U-shaped profile, a sheet of steel is attached to it using spot welding. Stiffening ribs must be provided on the inside of the door.
In the vertical direction, at least two stiffeners should pass, and in the horizontal plane, their number should be at least three. In this case, the rib passing in the middle part of the door can be broken by the lock. The space between these ribs is filled with thermal insulation material.
The side of the door from the side of the apartment is closed with any suitable material. For fastening the door frame, hinges with bearings are used. As additional protection, a special anti-removal pin is used, which extends when the door is closed.
For the manufacture of this part of the structure, one of the following materials can be used:
The latter option is most often used, provided the metal thickness is up to 5 mm. The door frames of the first two options are more deformed by bending and twisting. In addition, the profile pipe is easier to fix in the thickness of the wall, it has good stability and is not difficult to install.
The advantage of a curved sheet box is in its good heat and sound insulation properties, but they are less durable compared to boxes made of shaped pipes.
This parameter is determined depending on the width of the profile used for the base of the structure. For security reasons, it is better to make this parameter larger. But a door that is too thick can be unnecessarily traumatic.In this regard, it is better to stick to the standard thickness of 5 to 7 cm.
These parameters determine the final mass of the door and its resistance to burglary. An inexpensive door will have a steel sheet thickness of no more than one and a half millimeters. Such a sheet is easy to open with a simple canning knife. Too much thickness increases the weight of the door, but does not affect burglary resistance in any way. Therefore, it is better to use a sheet of steel about 3 mm thick. This creates both convenience and protective qualities.
It makes no sense to buy a door, on the inside of which a steel sheet is also welded. This is impractical, since during burglary, the presence of an inner sheet does not in any way affect access to the lock.
These elements are necessary in order to prevent curling of the canvas during a rough break. They prevent a part of the door leaf from bending or squeezing it out of the door frame.
There are three options for the device of stiffeners:
The latter option is considered the most successful, as it makes the door leaf as rigid as possible.
The very first thing to look for is the thickness of the steel, which is often less than 1 mm. Press on the door to check. If it bends, it means that such a door will not provide any protection. In addition, the low quality of the door is indicated by its low weight.
Other signs that can be used to distinguish a fake are the door peephole located at a low height and the shiny coating on the door. Low-quality Chinese-made doors often have problems with locks. Instead of high-quality filler, cellular cardboard is inserted into such doors, and one can only dream of having stiffeners.
Good insulation of the door prevents odors, sounds and heat from entering the apartment. First, for insulation, the inner space of the door between the stiffeners is filled. For this, mineral wool is used. It has excellent heat and sound insulation properties, does not burn and does not emit harmful substances. Some door manufacturers use polyurethane foam or expanded polystyrene instead of mineral wool. These materials do not absorb moisture, but at the same time, a significant disadvantage of these materials is their fire hazard.
The quality of insulation is also affected by the presence of seals. They can be made of silicone or rubber. These elements prevent extraneous odors from entering the home and increase the soundproofing qualities. In recent years, doors have been commercially available not with one, but with several seals. However, in practice, several sealing circuits do not affect the quality of the insulation, but only increase the cost of the door. You also need to take care of the finishing of the slopes. The cracks in the walls left after installing the door allow foreign sounds and smells to freely enter the apartment, and also speak of the negligence of the home owners.
Since there are so many types of locks, it is difficult to fully consider this issue. All models have their own distinctive characteristics, which determines the features of their installation and operation, but there are some general rules.
The front door lock must have a mechanism that fits entirely inside the door. Padlocks or overhead locks are not reliable and are best not used at all. It is imperative to use a latch, it greatly simplifies the door locking.
The selection of the number of locks should be based on safety and foresight considerations. From this point of view, the best option would be the presence of two locks of different designs.In the event of a break-in, an attacker will need two different sets of tools and it will take twice as long to break a door. And the foresight is explained quite simply - if one of the locks fails, it will be possible to temporarily use another lock and change the broken one without haste.
From the point of view of safety, the most reliable is the cylinder lock. The inner part of the mechanism of this lock consists of several pins. In order for the lock to open, they must be arranged in a certain order. But the disadvantage of such a lock is that, due to the design features, it can be knocked out of the door leaf.
In a lever lock, the main part consists of special plates - levers. It is somewhat easier to open, but difficult to break, since it is entirely inside the door leaf.
These measures are necessary to enhance protection and to create additional hacking difficulties. Therefore, it will be useful to find out which of the following is included in the door package.
Door hinges are available as external and internal. Each of these types of hinges has advantages and disadvantages. For example, the outer hinges look unaesthetic at their large size and can be cut with a special tool. At the same time, a door equipped with internal hinges is more expensive. To place the hinges, you need a place that stands out due to the useful door opening. With such hinges, the door does not open completely, and if you try to increase the opening angle, you can damage the door frame.
When choosing between a door with internal or external hinges, it should be taken into account that there is little likelihood that a burglar will cut the hinges, making too much noise. In addition, doors with such hinges usually have special anti-removable pins that will not allow the door leaf to be pulled out, even if the hinges are completely cut off.
Anti-removable pins are devices that are located inside the door leaf. When the door is closed, they are recessed into the thickness of the door frame, which prevents the leaf from being removed.
The latch makes it much more difficult to break into. There is no access to it from outside the door, so if the latch is closed, breaking the door is impossible.
The peephole should have a wide viewing angle so that you can see everything that is done from the outside.
The door must open outward so that it cannot be squeezed out with a jack.
As for the outer finishing of the door, here it is worthwhile to prefer the coating with hammer paint. This paint looks like the door was painted with paint and then hit with a hammer. Compared to other coatings, this finish has several advantages:
