Corrugated plastic, also known as Coroplast, is a tough and waterproof plastic sign material which resembles plastic cardboard. Inside, the hollow-fluted design makes it lightweight and easy to display! They're great for outdoor conditions and have a high tolerance for cold and hot weather temperature extremes.
We use 4mm (1/2") Coroplast for our Yard Signs. We print direct-to-textile, so you don't need to compromise your design to get the best price. Unlimited colors, text, and images! To apply sign, simply place the magnet onto a clean metal surface. Each Yard Sign comes printed on both sides (double sided) and includes an H-Stake for easy installation.
