The gate of this type are made of different materials, the most popular of them are steel sheets, trimmed with wooden planks. The construction of panel webs may be made from multicomponent sandwich panels.
Currently, this type of garage doorIt sets relatively rare. They are characterized by high consumption of electricity. In addition, due to the considerable weight of panel paintings lifting and rotating mechanism often fails.
The most resistant to cracking deemed garage door switchboard type. The easiest way to open the roller gate attackers.

The cloth of this type of gate is slidably connected sections. When they opened up the rails up and, reaching up to the ceiling, bend via swivel.
Door sections, usually made fromsandwich panels constituting a polyurethane layer thickness of 4 cm in a steel casing. Internal and external side sections galvanize and covered with polyester layer of any color. The outer side of the panels is often done in the form of broad bands or panels.
Within the sectional door leaf can be positioned on a steel sheet with a thickness of 0.5 mm to 3 mm. This does not affect the appearance and operation of the gate, but it will give them the strength of the armored doors.
