by Nathan Zachary

A wide variety of door models allows the modern consumer to choose the best option, taking into account their own needs and budget. Manufacturers note the highest demand for metal doors, of which there are a large number of varieties. A steel door can not only be purchased ready-made, but also made according to individual parameters.

What is the design of a metal door

The steel door is assembled from a frame with a metal profile and stiffeners, as well as iron sheets and hinges for attaching the door leaf. In terms of form, the design is made in the form of a single or composite product.

The thickness of the canvas is determined by the number of sheets, and the design can be:

  • single sheet;
  • two-sheet;
  • three-sheet (an additional metal layer is laid inside).

Regardless of the structure, the model is equipped with protective elements:

  • platbands – close the gap between the door and the opening;
  • porches – protect against hacking with a crowbar;
  • steel lock plate – do not allow to knock out or cut out the lock;
  • anchor elements – they will not let you remove the door even if the hinges are knocked down;
  • various locks – can be hinged, mortise, overhead.

Insulated doors come in three varieties:

  1. Special designs. They are distinguished by the presence of all the properties characteristic of insulated models – a high degree of thermal insulation, sound insulation, resistance to fire and burglary.
  2. Latticed doors. They are installed, as a rule, in the buildings themselves, but the presence of a heater allows their installation as input.

Properties of doors with increased sound insulation

In the manufacture of models of this classification, manufacturers use a special technology that you should pay attention to when buying:

  2. Compliance with the size of the gaps formed during the installation of hinges and key holes will achieve optimal sound insulation. For maximum effect, sealing rubber, plastic or silicone elements are used.
  3. The degree of insulation of the room also depends on the material from which the door leaf and frame are made. So, wooden and metal cladding will have different indicators.

The entrance door is a burglary-resistant structure consisting of a door frame with a metal leaf movably attached to it. When closed, the canvas is fixed in the box with a locking device or a locking mechanism.
