The steel fireproof rolling shutter doors are ordinary steel fireproof and composite steel fireproof rolling shutters. 复合型帘板由双层优质连续镀锌钢带，中间填充硅酸铝耐火纤维一次成型，其耐火时间更长，防辐射能力更好，并具有良好防盗及保温性能，它的控制箱可自带烟感温感探测器独立工作或与消防控制中心联网。 The curtain of ordinary steel fire-proof rolling curtain is cold-formed with 1.2mm thick high-quality continuous galvanized steel strip . The composite curtain is made of double-layer high-quality continuous galvanized steel strip , filled with aluminum silicate refractory fiber at one time. Longer time , better anti-radiation ability , and good anti-theft and thermal insulation performance . Its control box can work independently with its own smoke temperature detector or network with fire control center. 与低温熔断装置配合使用，火灾初期可实现在无人无电的情况下卷帘恒速自重下降关闭，达到防火分隔，阻止火灾蔓延的作用。 It can realize single action of a single roller shutter, linkage of multiple roller shutters , and use with a low temperature fuse device. In the early stage of a fire, the roller shutter can be closed at a constant speed under no one and no electricity, to achieve fire separation and prevent fire spreading effect.
