Our 10mm Coroplast signs are engineered for serious outdoor performance. Made from extra thick corrugated polypropylene, these signs offer significant rigidity and long lasting strength compared to standard 4mm materials.
This heavy duty material stands up to sun, rain, wind and day to day wear, making it the ideal choice for construction sites, real estate developers, traffic control, event management, fencing, jobsite branding and other high exposure environments. The added thickness prevents bending, warping and flexing even in harsh weather conditions.
Your artwork is printed in full color with UV resistant inks to keep your message sharp and visible. These signs can be easily mounted using screws, bolts, zip ties or placed into custom frames. When you need signage that continues working long after cheaper signs fail, 10mm Coroplast gives your project the reliability and durability it deserves.
