Products Description
ACM (Aluminum Composite Panel) is a high-performance sandwich-structured composite material, consisting of two thin coil-coated aluminum skins permanently bonded to a non-aluminum core (typically polyethylene (PE) or mineral-filled fire-retardant core).
Engineered for lightweight rigidity, exceptional flatness, and outstanding durability, ACM panels are widely specified for architectural facades, curtain walls, interior cladding, advertising signage, and decorative applications. The aluminum surfaces are finished with premium coatings (PVDF for exterior, polyester for interior) to ensure long-term color stability, UV resistance, and corrosion protection.
