Shutter door renovation

Current position: Yijie Fire >>> Renovation of rolling door
    There are many uses of rolling doors in daily life, including windproof and fireproof rolling doors, garage rolling doors, retail rolling doors, medical rolling doors, etc. The installation method of ordinary rolling shutter doors is the same as that of fireproof rolling shutter doors, but the installation requirements of fireproof rolling shutter doors are higher than ordinary rolling shutter doors. Because fire shutter doors are generally made of cold-rolled strip steel, they must be equipped with a temperature and smoke alarm system and an encrypted water spray system to work together. In the event of a fire, the signal is fed back to the fire control center through an automatic alarm system. The fire control center issues an instruction to automatically lower the shutter door and close the fixed time delay. Protect the roller shutter so that personnel can be evacuated in time.
