The difference between composite Steel Cửa cuốn chống cháy and common steel fire shutter is that the shutter plate adopts mechanical equipment. The main curtain board and auxiliary curtain board are extruded at one time, with smooth surface, no welding and high strength. 

The middle is filled with negative combustion heat insulation material, greatly reducing the backfire surface of the radiant heat, with fire-resistant long, superior performance, and can eliminate the water curtain protection system, can be full of steady decline in the class of the first-class fire zone partition role, vertical lift composite steel fire shutter with electric devices, can be achieved with the fire centre of the automatic and linkage control.
