防火卷簾門是現代高層建筑中不可或缺的防火設施。除了普通門的功能外，防火門還具有防火，隔煙，抑制火勢蔓延，保護人員疏散等特殊功能。它們廣泛應用于高層建筑，大型等密集場合。

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.

防火卷簾門主要用于大型（大型），大型，大型材料市場，大型展廳，工廠，倉庫等具有防火要求的公共場所。當發生火災時，防火卷簾門在火控系統的控制下根據預設程序自動降低（向下），從而防止火焰蔓延到其他區域并獲得實施滅火的寶貴時間。

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.

防火卷簾門與普通卷簾門基本相同。差異是:防火卷簾的內側和外側通常由鍍鋅鐵皮制成。在防火卷簾門的兩層鐵的中間，添加了石棉防火材料，并且還提供了一些防火。卷簾門可與相關的火控系統連接，當發生火災時，可實現自動“半滴”和“全滴”動作。

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.
