防火卷帘门是现代高层建筑中不可或缺的防火设施。除了普通门的功能外，防火门还具有防火，隔烟，抑制火势蔓延，保护人员疏散等特殊功能。它们广泛应用于高层建筑，大型商场等密集场合。

Fireproof rolling shutter doors are indispensable fire prevention 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 for personnel evacuation. They are widely used in densely populated areas such as high-rise buildings and large shopping malls.

防火卷帘门主要用于大型超市（大型超市），大型商场，大型专业材料市场，大型展厅，工厂，仓库等具有防火要求的公共场所。当发生火灾时，防火卷帘门在火控系统的控制下根据预设程序自动降低（向下），从而防止火焰蔓延到其他区域并获得实施灭火的宝贵时间。

Fireproof rolling shutter doors are mainly used in large supermarkets, shopping malls, professional material markets, exhibition halls, factories, warehouses and other public places with fire safety requirements. When a fire occurs, the fireproof rolling shutter door automatically lowers (downwards) according to a preset program under the control of the fire control system, thereby preventing the flame from spreading to other areas and obtaining valuable time for extinguishing the fire.

防火卷帘门与普通卷帘门基本相同。差异是:防火卷帘的内侧和外侧通常由镀锌铁皮制成。在防火卷帘门的两层铁的中间，添加了石棉防火材料，并且还提供了一些防火。卷帘门可与相关的火控系统连接，当发生火灾时，可实现自动“半滴”和“全滴”动作。

Fireproof rolling shutter doors are basically the same as ordinary rolling shutter doors. The difference is that the inner and outer sides of the fireproof rolling 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 in the event of a fire, it can achieve automatic "half drop" and "full drop" actions.
