Double Rail Double Shutter Inorganic Fireproof Shutter Door

◪1.The inorganic fire shutter is a double-track double-curtain structure with a certain thickness of atmosphere between the two curtains. Each curtain is composed of three layers of composite materials: the Intel fireproof refractory cloth is accepted by the fire surface, the heat-resistant radiation cloth or other high-temperature resistant cloth is received on the back fire surface, and the special heat-treated layer is selected for the intermediate heat insulation layer. Aluminum refractory fiber blanket with a face thickness of 10-20 mm.
◪2. It has soft texture and good bending function; it has high tensile strength, corrosion resistance and moisture resistance. The roller blind has small volume and small occupied space; the light weight (3.5kg/m2) can reduce the construction load carrying capacity, which is especially beneficial to the production device of the large span curtain door.
◪3.Flexible start-up, low noise and no need for water curtain protection, greatly reducing the cost of the project. The color is versatile and can be matched with the interior decoration to give a comfortable feeling instead of the chilly feel of steel.
