Fire Structural Board
As an improved product for the wall panels, roof panels and floor decks of light steel houses in the early stage, Bohengyi fireproof structural panels not only have A-level fireproof functions, but also have excellent water and moisture resistance, which solves the problem of products in the southwest and coastal areas of China. Problems with applications in generally humid environments in areas.

Class A fire resistance, water and moisture resistance, no formaldehyde, thermal insulation, shock resistance, and can effectively increase the service life of steel componentsg.

Application field
Prefabricated buildings/light steel villas/prefab houses/integrated houses' inner and outer wall base and roof.
