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.

防火卷簾門是在鋼質卷簾的基礎上，將傳動部件加以改造，配以防火電器等設備，從而實現防火作用:防火電機由防火電控箱控制，通過變速裝置驅動卷軸使卷簾門起閉，停電時也可使用防火電機上的手動搖柄，可實現手動操作。在機械相對運動處，采用聯軸器代替鏈輪傳動，道軌內摩擦處鑲嵌銅板或尼龍。更適合于使用或保管可燃性氣體、揮發性化學藥品等具有高發火性物品的工廠和倉庫等出現或可能出現爆炸的火災危險的環境。

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.
