MARC-Wh Fire protection swing doors

Principle of operation

Closing of the door is carried out by properly set hinges, which always make the door wing to return to the closed position. This solution therefore does not require connection to the SAP system.

Construction

• the wing of the door is made of galvanized steel sheet with a thickness of 0.5-0.7 [mm] and coated in basic RAL colours: 7035, 9002, 9010;

• the door wing panel is made of modified fire resistant mineral wool of Class A1, classified according to EN-13.501-1, internally reinforced by steel bars with a diameter of 8 mm (the design protected by European patent No.W02/079600A1);

• the door frame is optional, these doors may be installed directly on the wall;

• the hinges are integrated directly into the wing;
• the hinges may be installed in two options:
• - side wall,
  - floor - threshold;
•  around the wing, a swelling seal of Delta type is installed.
