Our corrugated plastic (Coroplast) panels are the lightweight, waterproof, and cost-effective workhorse of the sign industry — the same fluted polypropylene material used in yard signs, real estate signs, and campaign signs nationwide, at wholesale pricing with fast turnaround.

Whether your clients need high-volume yard signs, event signage, construction site notices, or short-to-medium-term outdoor displays, our wholesale Coroplast printing delivers clean, vibrant output on the most affordable rigid substrate available. We print, cut to custom sizes, and ship directly to your shop or your end client.

Why Sign Shops & Trade Businesses Choose Coroplast

Coroplast is the most widely used sign substrate in the industry for high-volume, cost-sensitive projects. Made from corrugated polypropylene plastic (the same fluted twin-wall structure as cardboard, but in waterproof plastic), Coroplast panels are lightweight, rigid, and completely waterproof. They won't absorb moisture, rot, or fall apart in the rain — making them the standard choice for outdoor temporary and semi-permanent signage.

The economics of Coroplast are hard to beat. It is the lowest-cost rigid sign substrate available, which makes it ideal for jobs where your clients need dozens or hundreds of signs at a competitive price point — political campaigns, real estate offices, seasonal promotions, event companies, and construction firms. For trade printers, Coroplast is the bread-and-butter product that drives volume and repeat orders.

Frequently Asked Questions – Coroplast Signage

What is Coroplast and what is it made of?

Coroplast is a brand name for corrugated polypropylene plastic sheet material. It has a twin-wall fluted structure similar to cardboard, but made entirely from waterproof polypropylene plastic. It is the most widely used substrate in the sign industry for yard signs, campaign signs, real estate signs, and any application requiring a lightweight, affordable, and weather-resistant rigid panel.

How long does Coroplast last outdoors?

Coroplast is waterproof and holds up well in rain, wind, and moderate weather. For most outdoor applications, Coroplast signs perform well for 6–18 months depending on UV exposure and environmental conditions. It is ideal for temporary to semi-permanent signage like campaign signs, event displays, and seasonal promotions. For permanent outdoor signage that needs to last years, we recommend upgrading to aluminum or ACM (Dibond) — both available at wholesale pricing through Print Wisconsin.

How does Coroplast compare to foam board, polystyrene, and aluminum?

Coroplast is waterproof and suitable for outdoor use, while foam board (foamcore) is not — foam board is strictly an indoor substrate. Compared to polystyrene, Coroplast is lighter, more flexible, and significantly cheaper, but polystyrene offers a smoother, glossier print surface. Compared to aluminum, Coroplast is a fraction of the cost and weight, but does not offer the same long-term outdoor permanence. For trade printers, Coroplast is the right recommendation when clients need volume, affordability, and outdoor durability for temporary to semi-permanent applications.

Do you offer wholesale or trade pricing on Coroplast panels?

Yes. Print Wisconsin is a wholesale-only print partner for sign shops, print resellers, and trade businesses. Our Coroplast pricing is built for the trade with no retail markup. We also offer volume discounts and custom quoting for large-quantity orders — especially campaign signs, real estate programs, and multi-location rollouts. Request a trade quote here.

Can I order custom sizes for Coroplast sign panels?

Absolutely. Our Coroplast panels are available in fully custom dimensions. Enter your exact width and height during ordering, and we will print and cut to your specifications. Popular sizes include 12x18, 18x24, and 24x36 for yard signs, but we can produce any size your project requires.

Can Coroplast signs be used with H-stakes and wire stakes?

Yes. Coroplast's fluted construction is specifically designed to slide onto standard H-frame wire stakes (also called spider stakes or step stakes). The corrugated channels run horizontally or vertically depending on orientation, and H-stakes insert directly into the flutes for quick, easy ground installation. This is the standard mounting method for yard signs, campaign signs, and real estate signs.

What print method do you use on Coroplast?

We use high-resolution UV direct-to-substrate printing, which produces vibrant, full-color output with crisp text and strong color saturation. UV ink bonds directly to the polypropylene surface, providing good adhesion and resistance to moisture and moderate UV exposure. This delivers a clean, professional finish even on the corrugated surface.

Can I print on both sides of a Coroplast panel?

Yes. We offer single-sided and double-sided printing on Coroplast panels. Double-sided printing is popular for yard signs, A-frame inserts, and any sign that will be viewed from both directions. Both sides receive the same high-resolution UV print quality.

Can you ship Coroplast panels directly to my client?

Yes. We offer blind drop-shipping and direct-to-client fulfillment for all trade orders. Your client receives a professionally packaged product with no Print Wisconsin branding on the shipment, allowing you to maintain your own brand identity throughout the fulfillment process. Coroplast's lightweight construction also keeps shipping costs low, even on large-quantity orders.
