Aluminum Composite Material – ACM, is often used for outdoor and indoor signage and channel letter backings. They can be used as wall liners and insulation as well.


The 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 a traditional aluminum sheet, reducing oil canning and rippling effects, while being more cost-effective than an aluminum sheet in the same gauge. Polymershapes can provide you with the highest quality from top manufacturers such as 3A Composites.

We can provide you with a variety of colours, finishes, and aluminum skin thicknesses, giving you a range of options to achieve the right mix of durability and cost. Available grades include economy, heavy-duty and lightweight. With trimmed, squared, cut-to-size, and sign blanks available, Polymershapes can provide the right ACM sheet for your application.
