We make all our signs from .080” thick aluminum. Other companies use steel which rusts, plastic which cracks or warps, or a thinner gauge aluminum (.060 or .040) which bends or buckles. We use 3M reflective sheeting and 3M UV resistant inks.
3M offers the following on their sheeting:
Size: 66" long post with 3x12" high intensity reflective on 1 side.
Other colors and lengths available. Call for details.
Size: 3.25 inch
Plastic back with center mounting hole.
2 high intensity bands with support rings around reflective bands for added tape protection.
8 lb. base is standard and is included.
