ACM (Aluminum-Composite Material) is most commonly made with a PE (Polyethylene) core and thin Aluminum skins on both faces. Well known trade names are Dibond and Alucobond. ACM panels offer great flatness and stiffness with minimum weight. They hold up very well outdoors and are available in a wide range of colors and brushed metal finishes. They are popular for architectural applications and signage with long service-life requirements. ACMs can also add a high-tech look to many of our plastic housing types.
