Entrance metal doors – features
The metal doors were greatly popular for their protective and refractory qualities. Steel structures are installed in both private houses and apartments and office buildings. They are considered strong and reliable due to their constructive features:
- The door leaf is the main part of the structure. It consists of a metal frame, external and inner steel sheets, ribs of stiffness and insulation.
- The box is a welded metal structure that comes with the canvas. The fewer welds in it, the higher the level of reliability.
- Special metal loops, often made by hidden, firmly hold the canvas, not allowing attackers to simply remove it from the loops.
- The seal that protects the dwelling from the cold, extraneous noise and smells.
- The quality of the lock on the entrance metal doors is more important. Modern models are equipped with a special anti -vandal mechanism, the opening time of which is relatively large without a key.
- The pen, eye and other fittings perform not only aesthetic function, but also additionally protect the home and its owners.
Metal doors – pros and cons of
During the repair or purchase of new housing, the owners often decide to install new entrance metal doors to the apartment or house. When making this decision, it is worth carefully studying all the pros and cons of steel structures. Their positive qualities are:
- A high level of home safety from robbers and vandals.
- Fire protection. It is worth noting that not all steel structures have this advantage. The degree of resistance to fire is affected by the thickness of the metal used and the features of external and interior decoration.
- Good thermal insulation qualities that are important for private houses. If the design is purchased for an apartment with a heated entrance, then this characteristic can be neglected.
- High sound insulation. Protection from extraneous sounds will become a useful bonus for those who live in a private house and for apartment residents.
- A large selection of internal options in the exterior decoration. For example, the input door with a mirror will fit perfectly into the interior of the apartment and will serve as an additional mirror canvas, which you can look immediately before leaving the house.
Steel structures have a number of disadvantages:
- Price. Simple models made of thin metal are inexpensive, however, with protective properties, they have dubious ones. The better and more reliable the option you like, the more expensive it will cost.
- Light weight. Reliable designs have an impressive weight. They are not easy to open and close to children and older people.
- High strength is not always a plus of the door. In the case of a fire, it will be difficult for firefighters to open it, and precious minutes will be spent on the hacking of the castle, and not on extinguishing a fire.

Entrance metal doors – filler
High -quality metal entrance doors are made to the house with the obligatory use of insulation, which is located between the inner and external steel sheet.
