Fire resistant rolling shutter doors are a type of fire and thermal insulation facility suitable for large openings in buildings. The product has played a certain role in design and installation technology. Fireproof rolling shutter doors are widely used in fire compartments of industrial and civil buildings, effectively preventing the spread of fire and ensuring the safety of life and property. They are indispensable fire prevention facilities in modern buildings.

防火卷帘门是在钢质卷帘的基础上，将传动部件加以改造，配以防火电器等设备，从而实现防火作用:防火电机由防火电控箱控制，通过变速装置驱动卷轴使卷帘门起闭，停电时也可使用防火电机上的手动摇柄，可实现手动操作。在机械相对运动处，采用联轴器代替链轮传动，道轨内摩擦处镶嵌铜板或尼龙。更适合于使用或保管可燃性气体、挥发性化学药品等具有高发火性物品的工厂和仓库等出现或可能出现爆炸的火灾危险的环境。

The fireproof rolling shutter door is based on the steel rolling shutter, and the transmission components are modified to be equipped with fireproof electrical appliances and other equipment to achieve the fireproof effect. The fireproof motor is controlled by the fireproof electric control box, and the rolling shutter door is driven by a variable speed device to open and close. When there is a power outage, the manual handle on the fireproof electric machine can also be used to achieve manual operation. At the point of mechanical relative motion, a coupling is used instead of a sprocket drive, and copper plates or nylon are embedded in the friction area of the track. It is most suitable for factories and warehouses that use or store flammable gases, volatile chemicals, and other highly explosive materials, where there is or may be a fire hazard of explosion.
