Double-gou flat embossed exterior thermal insulation metal panel, metal exterior fire-resistant decorative panel, is made by aluminum-zinc steel coil without passing through the metal embossing machine (smooth surface, no浮雕 patterns), directly entering the cold bending forming machine. While forming the two ends with insertion sockets, two middle grooves are formed on the surface of the board. This fire-resistant, insulating, and soundproof board is used for exterior wall thermal insulation and decoration. The board is mainly installed on the exterior wall, giving the wall a finished appearance that resembles painted wooden strips assembled together, which is very aesthetically pleasing. This polyurethane thermal insulation sandwich panel is widely used in exterior wall decoration of buildings, kiosks, dry-hanging insulating and soundproof walls, and fire-resistant thermal insulation for light steel villas.
