Fire shutter door is a necessary product of fire and smoke prevention in poor or poor areas, which can not be replaced by flat fire doors. At present, the size, width and height that domestic manufacturers can supply can reach 15m. It can usually be hidden in the ceiling, and the temperature and smoke detectors can be married. It can reach the smoke flag to temporarily reduce the door to 1.8m from the ground, making the area become a smoke blocking groove, in order to avoid the smoke spreading to other areas. When the temperature flag comes for a while, it is sure that the back door will fall to the ground, cut off the fire source, and send out an audible and visual alarm,

　　指点员工快捷散通。如灾区仍有未实时散通的员工，该门仍不妨由门两边的按钮将其提高到距地面1.8米的高度，在人逃生后门将延时封闭，为了避免火烟外窜。

　　Instruct the staff to spread quickly. If there are still employees in the disaster area who have not been dispersed in real time, the door can still be raised to a height of 1.8m from the ground by the buttons on both sides of the door, and the back door of people's escape will be delayed to close, in order to avoid the fire and smoke outside.

　　此外，防火卷帘门定做厂家针对卷帘门无电源的境况下不行施展用处的异常，相关单元已开拓了一哪类在无电或割断电源的境况下靠温度熔断敞开延缓离合器，使防火卷帘门靠自重匀速封闭，隔绝火情的“防火卷帘门熔断开释安置”，使防火卷帘门能在无电、无人的境况下仍能起到应有的用处。

　　In addition, in view of the abnormality that the custom-made fire shutter door can't be used without power supply, the relevant units have developed a kind of "fire shutter door fuse release and placement" which can open and delay the clutch under the condition of no power supply or cut off power supply, so that the fire shutter door can be closed at a constant speed by its own weight and isolated from fire, so that the fire shutter door can be without power and nobody Can still play its due role in the situation.

　　钢质防火卷帘 分为普通型钢质防火卷帘和复合型钢质防火卷帘。普通型钢质防火卷帘帘板按GB14102-93条件，采取1.2mm厚的优良连绵镀锌钢带冷弯成型。复合型帘板由双层优良连绵镀锌钢带，期间填充硅酸铝耐火纤维一次成型，其耐火时辰更长，防辐射才华更好，并具备优良防盗及保温功能。

　　Steel fire-proof rolling curtains are divided into ordinary steel fire-proof rolling curtains and composite steel fire-proof rolling curtains. According to gb14102-93, the ordinary steel fire-proof rolling shutter is formed by cold bending of 1.2mm thick fine continuous galvanized steel strip. The composite curtain plate is made of double-layer fine continuous galvanized steel strip, which is filled with aluminum silicate refractory fiber for one-time forming. It has longer fire resistance time, better radiation protection ability, and excellent anti-theft and heat preservation functions.

　　操纵箱可自带烟感温感探测器自立就业或以及消防操纵中间上网。可杀青单台卷帘单动，多台卷帘联动。以及低温熔断装置配合利用，火灾初期可杀青在无人无电的境况下卷帘恒速自重降落封闭，抵达防火隔绝，阻挡火灾延伸的用处。其产物结构、功能、外表在世界处于超越位子。钢质防火卷帘宽泛用于各类产业以及民用建筑的防火隔绝部位。如：堆栈、产业厂房、地下停车场、阛阓、宾馆饭馆、综合楼等。

　　The operation box can be equipped with smoke and temperature detectors for self employment, or the fire control can be connected to the Internet in the middle. It can be used for single rolling curtain and single action, and multiple rolling curtains can be linked. As well as low-temperature fuse device, in the early stage of fire, the roller shutter can be closed by falling at a constant speed under the condition of no electricity, reaching the purpose of fire insulation and blocking the extension of fire. Its product structure, function and appearance are in a position of transcendence in the world. Steel fire shutter is widely used in various industries and civil buildings. Such as: stack, industrial plant, underground parking lot, market, hotel, restaurant, complex building, etc.
