Fire resistant rolling shutter doors are indispensable fire protection facilities in modern high-rise buildings. In addition to the functions of ordinary doors, fire doors also have special functions such as fire prevention, smoke isolation, suppression of fire spread, and protection of personnel evacuation. They are widely used in densely populated areas such as high-rise buildings and large shopping malls.
Fire resistant rolling shutter doors are mainly used in public places with fire protection requirements, such as large supermarkets, shopping malls, large material markets, large exhibition halls, factories, warehouses, etc. When a fire occurs, the fireproof rolling shutter door automatically lowers (descends) according to the preset program under the control of the fire control system, thereby preventing the flame from spreading to other areas and providing valuable time for extinguishing the fire.
Fireproof rolling shutter doors are basically the same as ordinary rolling shutter doors. The difference is that the inside and outside of the fireproof roller shutter are usually made of galvanized iron sheet. In the middle of the two layers of iron in the fireproof rolling shutter door, asbestos fireproof material is added, and some fireproof measures are also provided. The rolling shutter door can be connected to the relevant fire control system, and can achieve automatic "half drop" and "full drop" actions in case of a fire.
Fireproof electric roller shutter doors have the same function as firewalls, achieving horizontal fire separation. It consists of curtains, seat plates, guide rails, brackets, rollers, boxes, control boxes, door rolling machines, limiters, thresholds, and manual quick opening and closing devices. It consists of 13 parts, such as button switches and devices, which are usually installed in areas that are not conveniently separated by firewalls. For example, opening elevator lobbies, escalators, large business halls in department stores, exhibition halls in exhibition buildings, and entrances to buildings. Fire resistant rolling shutter doors have been widely used in construction projects.
