As the original Aluminum Composite Material (ACM), ALUCOBOND® has a 50 year history in the Architectural market. The product was created to provide the architectural market with a durable, light-weight panel that was easy to fabricate and handle. The composite structure meant that the sheets could retain flatness while being produced in very large sizes. For many years now, there have been multiple thicknesses of ACM available: 3mm, 4mm, and 6mm.
