what does acm panel stand for

ACM stands for Aluminum Composite Material. It refers to a composite panel made by bonding two thin aluminum sheets to a non-metallic core. The aluminum skins supply weather resistance, stiffness, and a surface ready for high-performance finishes like PVDF or polyester coatings. The core—either polyethylene or mineral-filled—adds rigidity and lightweight properties.

In aluminum ceiling and facade systems, ACM panels are prized for their flatness, design flexibility, and capacity for concealed mounting. The sandwich construction allows for easy cutting, bending, and perforation, enabling complex architectural forms. Mineral-core ACM provides fire ratings needed for exterior cladding on tall buildings. The acronym ACM thus captures the material’s hybrid composition and its role as a versatile, durable cladding component.
