MARC-D Double wing gate
The wings of the gate in the closed position are locked by a bolt (upper and lower) and a lock latch. The door is kept in the open position by electromagnetic door holder connected to the central fire protection unit. In case of fire risk, the fire-fighting central unit releases the electromagnetic door holder and the gate wings, controlled by door closing coordinator devices, close the passage between the fire zones.
- the wings of the gate are made of galvanized steel sheet with a thickness of 0.5-0.7 [mm] and coated in three basic RAL colours: 7035, 9002, 9010;
- the gate wings are 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 gate wings are installed on hinges fixed to the door frame, which is provided also with an insulating element - the entire assembly is shielded by a set of covers coated in the standard colour of the gate;
- the gate frame is available in the following three versions, depending on the installation opening in the wall: corner, covering and internal.
