SANDWISH PANEL
Sandwich Panel is a composite material board composed of two layers of outer panels (usually metal or other materials) sandwiched by an intermediate filling layer (usually insulating material). Sandwich panels are commonly used in structures such as walls, roofs and compartments in buildings, industrial facilities, refrigerated warehouses, etc.
The outer panel of the sandwich plate is usually made of weathering steel, color steel, aluminum alloy and other metal materials, which has high strength and durability, and different plate thickness and color can be selected according to needs. The intermediate filling layer is generally made of polystyrene (EPS), rock wool, glass fiber, polyurethane and other insulating materials, which has excellent thermal insulation, sound insulation and fire resistance.
