Max Metal
Max Metal or ACM or Aluminum composite Material or Dibond is a substrate that is 1/8th of an inch thick that is factory finished typically in white on both sides.
Other thicknesses and colors are available.
It has Aluminum on each side with a composite polymer in the center.
Max Metal provides a low-cost, lightweight, rigid, and durable substitute for aluminum sheets or wood. The benefits of this is it is weatherproof and won’t rust and cost less than plywood. This makes this material perfect for indoor and outdoor signs and we use a lot of it for many styles of signs.
