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.
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.
