Polymetal is a very durable and lightweight product. It is two sheets of aluminum with a rubber composite between them which allows it to be extremely weather proof.
It comes in two sizes (3 mil & 6 mil) and 4' x 8' & 5' x 10' sheets. It also comes in several different colors, but can be covered with your color choice of vinyl or digital graphics. It can be cut into any shape or contour. Below are some examples of polymetal signs that we have done in the past.
