2 Coroplast Sign Products
Standard 4mm and premium 10mm corrugated plastic — both printed with UV-cured inks for waterproof, weather-resistant signage.
4mm Coroplast Signs
The industry-standard economical option for custom yard signs. Full-color printing on rigid corrugated plastic with UV-cured inks and waterproof durability — versatile enough for indoor use and durable enough for outdoor placement.
10mm Coroplast Signs
6mm thicker than the industry standard — our premium coroplast option delivers extra rigidity and durability for harsh weather conditions and high-traffic locations.
4mm vs. 10mm Coroplast
Choose the right thickness for your application, budget, and campaign duration.
4mm Coroplast
Industry Standard
Best for: Short-term campaigns, political signs, open house signs, events, and budget-conscious bulk orders.
10mm Coroplast
Premium Thickness
Best for: Long-term signage, high-wind areas, premium branding, extended campaigns, and heavy-traffic locations.
Built to Survive the Elements
Corrugated polypropylene delivers unmatched value for outdoor signage — waterproof, UV-resistant, and economical.
UV-Cured Inks
Our UV-cured printing process bonds ink directly to the coroplast surface, resulting in vibrant colors that resist fading from direct sunlight exposure.
Waterproof
Polypropylene plastic is naturally waterproof. Rain, sprinklers, humidity — nothing penetrates or warps your sign. Oils and solvents have no effect either.
Wind Resistant
The corrugated flute structure provides surprising rigidity for its lightweight. 10mm coroplast handles high winds that would bend thinner materials.
Fast Turnaround
Same business day production available. Standard orders ship next business day. We handle single signs and bulk orders of 200+ with equal speed.

Product Specs
H-stake note: When ordering H-stakes, place your sign order with width larger than height and select vertical flutes. H-stakes slide into vertical channels.
Flute note: The corrugated flute structure creates a very subtle linear effect (faint lines) on the surface. This is a natural characteristic of all coroplast and is generally not noticeable at normal viewing distances.
