The metal carved panels are made of environmentally friendly raw materials (the inner polyurethane layer is the same material as the inner insulation layer of refrigerators and air conditioners), which is non-toxic, odorless and pollution-free, giving the building green protection and decoration. The surface is a high-quality color embossed metal plate treated with a special layer. The middle layer is a flame-retardant treated hard high-density polyurethane foam insulation layer. The bottom surface is aluminum foil that plays a role in heat insulation and moisture-proofing. The protective layer. Because the wall panel itself has the characteristics of thermal insulation, waterproof and flame retardant, light weight and earthquake resistance, convenient construction, sound insulation and noise reduction, green and environmentally friendly, beautiful and durable, etc., and its assembly method of the panels is simple and practical, and is not subject to seasonal environmental restrictions, so it is easy to install and use. Very safe and convenient, suitable for all seasons.
