Sandwich Panel

Home » Products » Steel Materials » Sandwich Panel

EPS sandwich panel adopts the colored steel plate as surface board, and the self-extinguishing closed-cell polystyrene foam as core material. Produced in the automatic continuous molding machine by combining the pressed colored steel with high strength adhesives, it is a kind of high-strength composite building material. Featured with heat and sound insulation, fire-proof, anti-corrosion, anti-bending, fast construction, durability, and beautiful appearance, etc, the sandwich panel is widely used in ware houses, factories, exhibition halls, prefabricated houses, container houses and other industrial and civil buildings. In addition, the fire grade is B-class.
