Coroplast Printing for Every Sign You Need
Coroplast printing gives you lightweight, weather-resistant signs that hold up outdoors and still look sharp indoors. Whether you're directing foot traffic at an event, promoting a weekend sale, or planting yard signs across a neighborhood, corrugated plastic is the material most sign shops reach for first. It's affordable, it's tough, and it prints in vivid full color.
This collection pulls together the coroplast options you'll actually use, from Standard Coroplast Signs and Coroplast Yard Signs to specialty picks like Dry Erase Coroplast and Reflective Coroplast. 4OVER4.COM has printed for more than 150,000 businesses since 1999, so every sign here is backed by over 25 years of getting color, edges, and turnaround right.
What Makes Coroplast the Right Sign Material
Coroplast is a brand name for corrugated plastic sheeting, technically twin-wall polypropylene. Picture the plastic version of cardboard, except it shrugs off rain instead of falling apart in it. Those internal flutes make each sheet stiff and rigid while keeping the weight low, which is exactly why you see it on lawns, at construction sites, and in store windows everywhere.
The material resists moisture, chemicals, and UV on its own. A printed coroplast sign can sit through rain, snow, and full sun without warping, fading, or peeling. Most signs hold up for months outdoors, and some last years depending on conditions and finish.
Compared with other options, coroplast lands in the sweet spot. Aluminum lasts longer but costs more and weighs a lot more. Foam board looks clean indoors but dissolves in the rain. For temporary and semi-permanent signage where budget matters, corrugated plastic wins on value nearly every time.
Where Coroplast Signs Earn Their Keep
Coroplast isn't a one-trick material. It shows up in far more places than most people expect, and a few use cases keep customers coming back order after order.
Real estate agents burn through open house signs, directional arrows, and For Sale panels, and double-sided printing lets one sign cover both directions of traffic. Political campaigns lean on Coroplast Yard Signs because they're cheap enough to hand out by the hundreds, light enough for volunteers to carry, and tough enough to survive weeks on a lawn. The fluted channels accept standard H-wire stakes, so setup takes seconds.
Retailers and event planners use coroplast for grand openings, sidewalk sales, and festival wayfinding, then swap the artwork out each season without blowing the budget. Contractors zip-tie job-site and safety signs to fences, where the material takes dust, rain, and rough handling without cracking.
Design Choices That Make Coroplast Read Well
A strong coroplast sign starts with a few smart calls before you upload artwork. Most of these signs get read from a distance, so keep your headline text large, roughly three inches tall for every 25 feet of viewing distance, and cut the fine print. If it isn't clear at a glance, it isn't working.
Contrast does the heavy lifting outdoors. Dark type on a light background, or the reverse, reads best, while combinations like red on orange or yellow on white blur together from across a parking lot. Bold, saturated colors print beautifully on coroplast's smooth white surface.
Match the product to the job and you'll get better results. Dry Erase Coroplast suits menus and schedules that change often, while Plastic Coroplast Signs give you the classic outdoor durability people expect. For a die-cut shape or an odd dimension, our custom project option opens up sizes well beyond the standard rectangle.

Coroplast FAQ
What sizes do Coroplast signs come in?
Standard sizes include 12x18, 18x24, and 24x36 inches. Custom dimensions are available too, so if you need a non-standard size you can request it during checkout.
What are Coroplast signs made of?
They're printed on 4mm white Coroplast, which is corrugated twin-wall polypropylene. The fluted core keeps each sheet rigid and lightweight while resisting moisture, chemicals, and UV exposure outdoors.
How fast can I get my Coroplast order?
Orders ship on the schedule we quote, backed by a 99.8% on-time delivery record, and 82% of orders actually ship early. If you're on a tight deadline, our team can help you plan the timing.
What finishes and add-ons are available?
You can choose single-sided or double-sided printing, add grommets on the top corners or all four corners, include H-stakes for yard signs, or upgrade to dry-erase lamination or reflective film.
Can I order Coroplast signs in bulk?
Yes. Larger quantities bring the per-unit cost down, which makes coroplast a smart pick for campaigns, events, and multi-location rollouts. Small runs work fine too when you only need a few.
How should I set up my artwork?
Submit files at 150 DPI or higher in CMYK color mode with 0.125 inch of bleed on all sides to avoid white edges and color shifts. Blank templates pre-sized to common coroplast dimensions make setup easier.
What customers are saying
Verified feedback from real 4OVER4 buyers.
“I stake these at open houses every weekend, and the flutes are stiff enough that the H-stakes slide right in without splitting the board.”
“Bought a bulk order for a school fundraiser, and the bright yellow held up even after a month baking in the parking lot.”
“Sturdy board and clean printing. One sign in my batch had a slightly soft corner, but support shipped a replacement before I even finished writing the email.”
