Sandwich Panel

Description

Heat-insulating sandwich panel composite production line is a new type of building material with high strength, light weight, strong and durable, and beautiful appearance by laminating the book high strength material on the single and double-sided outer layer of thicker and lighter inner core material. Generally the outer layer is made of 0.3-0.6mm color steel plate, but also stainless steel plate, aluminum plate, plastic plate and other materials. The inner core is made of thicker and lighter materials such as EPS spontaneous self-extinguishing polyurethane, foamed polyurethane and other fire-resistant core materials such as glass wool, and the thickness is between 50-300mm, which can be chosen arbitrarily. It can be used in public buildings, industrial plants, large warehouses, large-span roofs, walls, cold storage, purification rooms, air conditioning rooms and other places. Because of its light weight (equivalent to 40-60 molecules of ordinary bricks), high strength, beautiful appearance, convenient construction and short construction period, it has become one of the more ideal new building materials in today’s building materials industry and is widely used.
