Coroplast® is a go-to material in the screen printing industry and signage world. Perfect for both indoor and outdoor use, it’s tougher than corrugated fiberboard, lighter than traditional plastic sheets, and completely waterproof and stain-resistant.

Our Coroplast® sheets feature 18″ flutes, meaning the corrugation runs vertically on an 18″ x 24″ sheet—ideal for step stakes and directional signs.
