The “Tank” of the Sign World. When a standard yard sign just won’t cut it, you step up to 10mm. At nearly half an inch thick, this isn’t just a sign—it’s a structural solution. If you’re tired of signs that bow in the wind or look “flimsy” on a high-end job site, this is the heavy-duty upgrade you need.

Why 10mm?

• Zero Flex: Unlike standard 4mm boards, 10mm Coroplast stays flat and rigid, even in large formats like 4’x4′ or 4’x8′.

• Professional Presence: It has a “heft” to it that commands attention. It feels solid in your hands and looks premium to your clients.

• Built for the Elements: This is our go-to recommendation for semi-permanent outdoor signage, construction site boards, and high-wind environments.

• Vibrant UV Printing: We print directly onto the board with UV-stabilized inks for a crisp, professional finish.

⚠️ Pro-Tip: Protecting Your Investment

While our UV inks are tough, the sun is tougher. For any sign staying outdoors for more than 3 months, we strictly recommend Lamination.

• Why? Lamination acts as a “sunscreen” for your graphics, preventing fading and protecting the surface from scratches and road grime. If it’s staying outside for a season or longer, lamination is the only way to keep it looking brand new.

Best Used For:

• Real Estate Development: Large “Coming Soon” or “For Lease” site signs.

• Construction & Wayfinding: Rugged enough to be screwed into plywood or mounted to posts.

• A-Frames & Inserts: Perfect for heavy-duty sidewalk displays that stay upright.

• Custom Cutouts: Its thickness makes it ideal for life-size standees or custom-shaped rigid displays.
