BCP - Aluminium Composite Panel

Blackburns have developed BCP - Its own range of Aluminium Composite Material (ACM), believed to be superior to other composite products on the market and at the cutting edge of technology.

Blackburns Composite Panel (BCP) is particularly suitable for sign and display applications due to its high strength, rigidity and durability. This rigidity is achieved by its construction of a polythene core sandwiched between two thin aluminium sheets. Composite panel also known in the sign industry as Aluminium Composite Material (ACM) is widely used throughout the road traffic sector helping to combat theft due to its significantly lower value.

This combination of the materials and manufacturing process provides a product that can be up to a third of the weight for the same rigidity of more traditional sign and display panelling products

All of Blackburns composite panels are available pre-finished in polyester paint, offering a five year product guarantee. In addition to standard colours, any colour is available providing you can satisfy a minimum production quantity.

Blackburns Composite Panel (BCP) can be supplied in full sheets, cut into bespoke sizes and shapes or manufactured into sign trays.
