Coroplast signs are a lightweight, durable, and cost-effective solution for promoting businesses, events, real estate, and temporary signage needs. Available in a variety of sizes—from standard yard signs to larger formats like 4' x 8'—they offer flexible options to fit any project. Made from corrugated plastic, these signs are weather-resistant and built for outdoor use. We offer both 4mm thickness for everyday signage and 10mm thickness for added strength and durability, giving you the right option whether you need short-term promotion or a more heavy-duty display.
