Recently, a fire broke out in Changsha. Fortunately, neither the owner nor the pet dog is in danger. But the two photos below are enough to prove the importance of the fire door. Let's take a look at the huge contrast between the two sides of the doors after the fire that day.
Outside the fire door, the walls and door have been completely blackened. Inside the fire door, all the things are basically intact except that the door frame is blackened.
As a line of defense on the fire field, the fire doors not only need to be fire-proof and heat-insulating, to prevent the fire from spreading, but also to prevent the smoke from invading the room. It provides the final guarantee for people's survival in the fire.
