In order to prevent fires in some large shopping malls, fire and security doors are installed between many cargo spaces. If a fire occurs, stop the fire from spreading in time by closing the fire door. The filler used in the door plays a great role in the fire prevention function. Almost all fireproof and anti-theft doors on the market use glass magnesium fireproof board as a fireproof material.
