Supplementary Information-Fireproof Material Grade

Class A: Non-combustible building materials, materials that hardly burn.

Class B: Flame-retardant building materials: Flame-retardant materials have a good flame retardant effect. It is difficult to catch fire in the air or under the action of high temperature, and it is not easy to spread quickly, and the combustion stops immediately when the fire source is removed.

Class C: Flammable building materials: Flammable materials have a certain flame retardant effect. When exposed to an open flame in the air or under the action of high temperature, it will catch fire immediately, which will easily lead to the spread of fire, such as wooden pillars, wooden roof trusses, wooden beams, wooden stairs, etc.
