Do Not Pass Signs (R4-1)

ACM, or Aluminum Composite Material, Do Not Pass Signs are comprised of a thermoplastic core of low density polyethylene (LDPE), bonded between two sheets of aluminum. The aluminum sheets have a high performance polyester coating. This high-tech replacement for solid core aluminum signs delivers sign blanks that are light weight, while at the same time, rigid and durable. ACM sign blanks offer excellent outdoor ‘weather ability’. Lastly, to the average person, ACM signs are virtually indistinguishable from traditional, solid core aluminum signs.
