These signs can be CUSTOM made or you can choose from many common signs already in STOCK. Standard signs are manufactured from economical yet DURABLE materials. They are .040 or .080 thick aluminum with powder coated paint which is then baked on. Many standard and in-stock parking and directional, handicap accessibility, gun or weapon control and regulatory signs are also AVAILABLE with an ENGINEERING grade reflective sheeting on .080 aluminum. This material is not only durable, but it will REFLECT at night when light hits it. These parking control and regulatory signs meet most State and Federal D.O.T. SPECIFICATIONS.
