The metal-coated prefabricated wall material is produced by independent research and development and intelligent automatic production line. The board surface combines a new type of composite material of galvanized sheet and PVC film. It has the good strength and processing performance of metal materials, and also has the PVC and other polymer films have excellent decorative properties, selection diversity, corrosion resistance and other characteristics. The products have been tested by more than ten national building material tests, such as combustion performance, formaldehyde, air sound insulation, breaking load, etc., and meet the requirements of fire protection and environmental protection.
