Aluminum Composite Sign Blanks – Rounded Corners

Aluminum composite sign blanks come in many sizes. Our sign blanks come with rounded corners. This is due to the sharpness of the aluminum edges for your safety. These are wind resistant when properly attached between two posts.  If you need a specific size, please check out the customization tab for more information.

Aluminum Composite Material (ACM) is a rigid sheet made of two sheets of aluminum, bonded to a polyethylene core. Due to its manufacturing, ACM is 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 cut, roll-formed, or routed. As a result, it makes 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 sheets, reducing oil canning and rippling effects, while being more cost effective than aluminum sheets in the same gauge.
