Industry Leading Durability
Our Plastic signs are made from 55 mils thick, tear-resistant HDPE (High Density Polyethylene) material. These plastic signs are perfect for indoors and limited outdoor use. but most signs last longer. Our signs are laminated for enhanced performance. Semi-flexible plastic allows the sign to conform around slight curves. Our Danger - Keep Out, Hazard Area signs are better than comparable styrene signs, which become brittle and break.
