ACM panels provides a flat surface comparable to much thicker aluminum, at a more reasonable price. When you desire larger panel modules or panels with greater impact resistance, aluminum composite material is the way to go.
Aluminium composite material (ACM) is a flat panel made from two thin aluminium sheets bonded to a non-aluminium core, between three and seven mm thick. The panels have a painted or metallic finish, for example a copper or zinc effect.
