The surface layer consists of top and bottom alloy-coated aluminum sheets, with an XPS extruded polystyrene (XPS) core material bonded together under high pressure. XPS XPS boasts extremely high compressive strength, virtually zero water absorption, and consistently stable thermal insulation performance; the aluminum sheets are weather-resistant, corrosion-resistant, highly decorative, and resistant to fading. The entire panel combines load-bearing, moisture-proofing, thermal insulation, and decorative functions, making it particularly suitable for roofing, exterior walls, cold storage floors, and factory enclosure projects in humid areas.
