As friends who do architectural design know, fireproof rolling shutter is not an ordinary rolling shutter door.
It is a key facility in the fire compartment of a building, equivalent to the “fire barrier” of our building.
Whether its design is done well or not directly affects whether personnel can be safely evacuated and property losses can be reduced in the event of a fire.
Therefore, it must not be careless and must be strictly followed according to national regulations, combined with the actual situation of the building, and slowly polished.
Do not leave fire safety hazards due to momentary negligence.
