The Aluminum Composite Panel (ACP) is a lightweight and versatile building material composed of two thin aluminum sheets bonded to a core material, typically made of polyethylene or mineral-filled material. This sandwich structure provides high rigidity and strength while maintaining a low weight. The aluminum sheets offer excellent corrosion resistance and durability, while the core material provides insulation and soundproofing properties. ACPs are available in a variety of colors, finishes, and sizes, making them suitable for a wide range of architectural and signage applications. They are commonly used in exterior cladding, interior decoration, signage, and advertising due to their aesthetic appeal, ease of installation, and cost-effectiveness.
