4Hours Warehouses Super-grade Double-track Roll Up Fire Door Fire Shutters For Windows
Super-grade Fire Roller Shutter
The super-grade fire shutter adopts a double-track structure, and the transmission mechanism uses a roller shutter to drive two parallel reels to take off and land at the same time, and a certain air insulation layer is left between the two curtains.
The curtain surface is made of aluminum silicate fiber cloth and coated with a rubber layer with enhanced fire resistance. On the surface it is covered with a thermal radiation cloth. The interior is filled with aluminum silicate fiber blanket to enhance the thermal insulation performance.
Low Operating Noise;
Great Reduction of The Project Cost Thanks To Removal of Water Curtains;
Good appearance decoration effect and Convenient Construction.
The fire resistance duration is longer than 4 hours, the highest single point temperature of the backfire surface is 63.5 degrees Celsius, and the average temperature of the backfire surface is 55.6 degrees Celsius. Wind pressure resistance meets the requirements of GB14102-2005.
