The appearance of the metal carving board is simple and atmospheric, and the installation steps are simple. The surface is a high-quality color relief surface metal plate treated by special layers. The middle layer is a hard high-density polyurethane foam insulation layer treated by flame retardant, and the bottom surface is a aluminum foil protective layer that plays the role of heat insulation and moisture resistance. Because the wall board itself has the characteristics of thermal insulation, waterproof and flame retardant, light seismic, convenient construction, sound insulation and noise reduction, green environmental protection, beautiful and durable, and at the same time, because of the simple and practical assembly of the board, it is not restricted by the seasonal environment, so the installation and use is very safe and convenient, suitable for all seasons.
