The main curtain plate and the auxiliary curtain plate are extruded at one time, with smooth surface, no welding and high strength. The middle is filled with non-combustible insulating fire materials, which greatly reduces the radiated heat on the back fire surface. It has a long fire resistance time and superior performance. It can also eliminate the need for a water curtain protection system and can meet the breaking effect of various fire protection zones
The vertically lifting composite steel fire-proof rolling shutter is equipped with manual and electric opening and closing devices, which can realize automatic and linkage control with the fire protection center. The product has been tested and its fire resistance time is more than 1 hour
