ACM (Aluminum Composite Material) Sheet

Aluminum composite material (ACM) is a rigid panel built from two thin aluminum skins bonded to a solid polyethylene core, delivering the flatness, durability, and finish quality of sheet aluminum at a fraction of the weight and cost. The sandwich construction gives ACM exceptional rigidity-to-weight and dimensional stability — 1/8" panels stay flat across large spans without oil-canning, warping, or the flex that plagues single-skin metal and plastic sheet. The aluminum faces carry a factory-applied painted finish that resists fading, chalking, and weathering through years of outdoor exposure, and the material will not rot, rust, delaminate, or absorb moisture. Available in white and black.

ACM is the industry standard for exterior and interior signage — dimensional letters, wayfinding, monument and post-mounted signs, real estate and construction signs, and vehicle and fleet graphics — as well as architectural wall panels, display and trade show fixtures, machine and equipment panels, and photo and print mounting. It is the preferred substrate for digital printing and vinyl graphics: the painted surface accepts inks and adhesives readily and holds them without the outgassing or lifting common to plastic substrates. Fabrication is straightforward with standard shop tooling — it cuts on a panel saw, routers cleanly, drills and punches without cracking, and can be routed and folded to form returns and boxed edges. Cut-to-size service is available for exact-fit panels.
