About Wholesale Coroplast Signs

Corrugated plastic — commonly called coroplast — is the backbone of the outdoor sign industry. Its lightweight construction, weather resistance, and low cost make it the material of choice for yard signs, political campaigns, real estate riders, and countless short-term signage applications. At SignMaster, we print coroplast using direct UV printing technology, which bonds inks directly to the substrate for sharp, full-bleed colors that resist fading even in prolonged sun exposure.

When you order double-sided coroplast, we print on opaque stock so artwork on one face never bleeds through to the other — a problem with cheaper translucent materials. Flute direction depends on the sign — 4'x8' panels run horizontal, while standard yard signs typically run vertical. Just let us know your preference on the order.

Our coroplast is available in three thicknesses to match the demands of your application. The lightweight 4mm is perfect for standard yard signs and short-term use. The 6mm adds rigidity for larger formats and windier environments. The heavy-duty 10mm is ideal for construction sites, large format installations, and anywhere extra durability is needed. All thicknesses can be digitally die cut to virtually any custom shape, and we stock sizes up to 4 feet by 8 feet.

Coroplast is the only substrate in our die-cut lineup — its low cost and ease of cutting make it the best fit for short-run custom shapes. For die-cut shapes in other materials, contact our sales team for a custom quote.

With no minimum order quantities and free UPS Ground shipping, you can take on any job with confidence and build in a healthy margin without inflating your client's invoice.
