Aluminum composite panel (ACP) is a lightweight multi-layer building material with a sandwich structure, where two pre coated aluminum panels are bonded to a polyethylene (PE) refractory filler core. This design combines the durability and weather resistance of aluminum with the insulation and flexibility of the core, providing excellent corrosion resistance, UV resistance, and extreme temperature performance. ACP offers a variety of colors, finishes (metal, matte, wood grain), and fire ratings (such as A2) to ensure compliance with safety standards.

They are widely used in modern architecture and are ideal for exterior facades, interior cladding, signage, and decoration projects due to their lightweight, cost-effectiveness, and ease of installation. Their recyclability and low maintenance further enhance their attractiveness in sustainable buildings.
