Grade A fireproof metal composite board uses non-combustible inorganic material as the middle core material, both sides are rolled or coated metal plate as decorative protective layer, through a special process composite, is a kind of green and environmentally friendly fireproof building materials. The main components of the non-movement material are non-combustible inorganic materials such as silicon, aluminum and magnesium, which can be directly combined with the metal panel for a single composite molding, or can be produced separately for secondary composite molding with the metal panel. Both sides of the metal layer can be selected aluminum, copper, titanium zinc, stainless steel and other metal materials, the surface coating can be fluorocarbon, polyester, nano self-cleaning, laminating and other processes, a wider range of options, more decorative.
