Fire rating classification of wall panels

The fire resistance rating of wall panels is classified according to national standards, mainly into the following categories:

Class A
Class A fire resistance rating means the wall panel is completely non-combustible and effectively prevents the spread of flames. Class A wall panels are widely used in high-requirement buildings, airports, subways, and other public places.

Class B1
Class B1 fire resistance rating means the heat release of the wall panel is within a certain range, making it difficult for fire to spread. Class B1 wall panels are suitable for commercial, office, and residential buildings.

Class B2
Class B2 fire resistance rating means the wall panel is flammable, but when burning, it does not burn continuously, and the flame spreads slowly. Class B2 wall panels are suitable for indoor public places and industrial buildings.

Class C
Class C fire resistance rating means the wall panel is flammable, and the flame spreads relatively quickly. Class C wall panels are suitable for indoor public places and industrial buildings, but the requirements are not high.
