Aluminum Composite Material – widely referred to as ACM – is a rigid sheet made of two sheets of pre-finished aluminum, bonded to a polyethylene core. Light in weight, yet highly durable, ACM sheets are often used for outdoor and indoor signage and channel letter backings, as well as wall liners and insulation.
Aluminum composite material is easily routed, cut, or roll-formed, making it a material of choice for architectural faces and building cladding, or even as a replacement for steel. ACM also lays flatter than traditional aluminum sheet, reducing oil canning and rippling effects, while being more cost effective than aluminum sheet in the same gauge.
