The primary function of entrance doors is protection against burglary and an aesthetic appearance is also important. The most durable material used for modern doors is metal, namely steel, so you don’t have to worry about reliability. To improve its appearance, the slab is decorated on both sides.
In addition to the fact that it is pretty difficult to damage and crack such steel entry doors, they provide good heat and sound insulation. Therefore, this choice will provide comfort for the whole house.
You will learn about modern technologies for the installation and production of doors from our article.
Types of metal doors
To fully delve into the issue of the appearance of entrance doors, one shouldbriefly describe the production technologies that are currently used.
Pipe-angle method. It is used very rarely but still used. Assortment, respectively, is also tiny. Such doors are the most budgetary but have disadvantages. Since manual welding is used in this technology, the fabric has a poor shape and often does not meet existing standards.
Bending-rolling method. This technology is used in large-scale production and provides geometrically accurate products in shape and of equally good quality. The door slab itself, in this case, is thicker and heavier. This directly affects the price – higher than that of doors made by the pipe-angle method. Also, because the slabs is more comprehensive, you can install complex locks – to further secure the entrance. A frame is placed inside – vertical and horizontal partitions that do not allow the door to be pressed through.
There is also a combined method when different profiles are used – bent and ordinary.
What metal entrance doors are the most reliable
It would be incorrect to assert that there are doors that cannot be cracked. Here we are talking more about how to complicate hacking as much as possible. Door designers try to predict the actions of intruders and strengthen all weak points.
The outer layer of the door plays a primary role in the design. This material determines the appearance and service life of the product. A sheet of metal can be from 1.2 to 2.5 mm. It would seem that the thicker the slabs, the better, but there is one caveat. A thick sheet makes the entire door heavier, giving an additional load on the hinges. Such an unreasonable “build-up” may in the future provoke a warp of the door or even damage the wall to which it is attached. European manufacturers consider the optimal size to be 1.5 mm. Domestic ones sometimes allow more than 2 mm.
Reinforced steel doors are more often used in exceptional cases – in banking institutions, warehouses, and shops. But if you still decide to install them at home or in the country, do not forget about special fittings – appropriate steel hinges and a strong handle.
Doors with a sheet of metal up to 1 mm break easily and quickly, even without special equipment. But oddly enough, such models can also be found on the market, mainly a Chinese manufacturer that attracts low-priced consumers.
What about fittings?
We figured out the slabs. Now, let’s talk about “accessories” – fittings. The door lock often becomes a weak point. Burglars destroy the lock block lining, which gives access to the mechanism to open the door. To prevent such a scenario, it is necessary to equip it with overlays. They can be made of manganese, nickel, or armored. Usually, they are installed for an additional fee – all the details should be checked with the company where you place the order. There are doors with a different characteristic – a door slab recessed into the box. They cut off access to the connector between the door slab and the frame (through this joint, attackers often gain access to the lock bolts by bending the trim ).
- Metal sheet
- MDF panel
- Wool insulation
- Armored lock pad
- Outer sheet, finish
- Hinge with bearing
- Clamping bar
- Anti-removal pin
The door platband must be no less reliable than the door itself. The door system must have a unique profile that will restrict access to the gate around the entire perimeter where it comes into contact with the frame. It would be best if you did not forget about the loops either – they hold the canvas, so you need to choose the identical coils for heavy metal. The number of loops does not affect their stability, and the installation process becomes more complicated. In practice, more often p9utting these types of loops:
• with “ball”
• thrust hinges
• axleless hinges

Heat and sound insulation are the main characteristics of the front door.
A house is where you want to protect yourself from extraneous sounds, whether an apartment or a private home. No one wants to hear everything that happens on the landing. And in a private home, the door immediately gives access to the street, so it is imperative to keep warm in the cold season. Sound and heat insulation is provided by internal fillers that are not visible. There are several options for modern insulating materials that manufacturers use:
• Basalt mineral wool
These materials are also resistant to high temperatures and their basic properties.
Chipboard or MDF plates, located under the outer metal layer, help to insulate the door. Doors from Europe use special soft foam instead of mineral wool. It is poured into the door in a liquid state, where it solidifies, forming a monolithic structure.
A unique contour (usually made of rubber) is placed along with the door’s shape, which prevents the penetration of noise. In addition, there is a frost-resistant contour in the design of the entrance doors, which is especially important for a private house.
