Aluminium composite panels (ACP), made of aluminium composite material (ACM), are flat panels consisting of two thin coil-coated aluminium sheets bonded to a non-aluminium core. ACPs are frequently used for external cladding or facades of buildings, insulation, and signage.

Aluminium composite has become the most widely used sheet substrate within the sign and display industry due the many benefits which this material provides. Other trades and industries are now discovering the benefits of this stable, durable material.

The polyethylene core of your Aluminium Composite sheet is faced with two thin sheets of aluminium. This aluminium is bonded onto the core during the manufacturing process and it is virtually impossible to separate the layers of material once they have been bonded.

Aluminium Composite is supplied in a range of finishes. These finishes are applied to the external aluminium faces during the manufacturing process. When you buy a full sheet of Aluminium Composite you will find that the decorative finish is consistent throughout. This delivers a consistent, smooth finish across the entire surface area.

Depending on which brand of Aluminium Composite you buy the thickness of the external aluminium faces will be either 0.4, 0.3 or 0.2mm. If you are using aluminium composite as a flat panel product the face thickness is not critical.

If, however, you want to form your Aluminium Composite into shapes such as columns or sign trays the face thickness has an impact. From our experience of actually making formed Aluminium Composite structures it is best to use a sheet with no less than 0.3mm face thicknesses. Any less than this and it becomes difficult to make neat bends.
