Our Aluminium composite board Printing is great for long term signage and is perfect for outdoor use, the board has a very smooth front surface giving it a superior look. NOTE: The maximum size Aluminium composite available in one piece = 1220mm x 2440mm. Sizes above this are not a problem, but will require a join when fitting. This is commonplace when fitting large signage. Please allow upto 2 working days to what's been advertised.
