What Are Reflective Coroplast Signs?
Reflective Coroplast signs are water-resistant outdoor signage. They’re made of corrugated plastic, finished with a layer of reflective vinyl. The special reflective surface makes graphics visible in the dark. When headlights shine on them, the signs reflect the light and illuminate. They’re resilient, long-lasting, and withstand outdoor conditions.
Reflective Coroplast is a perfect product for roadside and traffic signs, real estate posters, political and directional displays, event, construction, and safety warning signs. Our reflective graphics work great with round-the-clock advertising campaigns.
Make your own custom reflective Coroplast sign with Square Signs to stay visible day and night! You can create your own display with our intuitive design tool. Upload your logo, design from scratch, use our built-in AI image generator, or get a head start with one of our ready-made templates.
Printing Technology and Materials
We apply UV-cured CMYK inks directly onto the material. We provide single- and double-sided printing, depending on your needs and installation location. For double-sided printing, you can print the same or different designs on both sides of your display.
Our custom reflective Coroplast signs are made of high-quality 4mm white Coroplast as the base material. It’s super durable and weather-resistant. The reflective properties come from a 4 mil reflective adhesive layer applied to the surface. The layer gives reflective Coroplast signs 24/7 visibility.

Common Uses of Custom Reflective Coroplast Signs
Reflective Coroplast signs are the premier choice for messages that must be seen both day and night. They’re similar to reflective lettering and decals thanks to their brilliant reflective surface.
You can use reflective Coroplast printing in many industries, such as real estate, political campaigns, wayfinding, or safety campaigns.

Real Estate
Reflective Coroplast signs are a budget-friendly, practical choice for showcasing real estate campaigns. The signage provides excellent visibility day and night. You can feature property listings, open house signs, and directional posters. Place the signs along the roadside where drivers can spot them even at night, illuminated by vehicle headlights.

Traffic and Direction
Reflective Coroplast signs are indispensable for getting a driver's attention, especially at night. Reflective Coroplast printing uses the light from vehicle headlights to become luminous, like reflective aluminum signs. These posters help drivers find their way on the long route, providing directional and warning information.

Large Events
Guests need guidance at large events, and things change fast. Use reflective Coroplast signs for temporary events, directing traffic to the VIP entrance, pointing people to parking spots, or marking exit routes. They're light enough to move quickly if the layout shifts.

Construction Sites
On a job site, safety is a priority, and reflective Coroplast signs work great as warnings. They ensure warnings like “Hard Hat Area” or “Caution: Heavy Equipment” are visible to everyone from the early-morning crew to late-night delivery drivers. They're tough, cheap, and get the job done in rough environments.

Political Campaigns
Custom reflective Coroplast signs will help you win the visibility war on a busy street. A non-reflective sign disappears the moment the sun goes down. The one with a reflective finish keeps your candidate's message active all night long. They’re the essential tool for campaign visibility.

Promotional Campaigns
Reflective Coroplast printing works perfectly for promotional campaigns that need visibility day and night. They’re popular for outdoor marketing, roadside advertising, limited-time offers, event promotions, and big sales.

Installation
You have several options to set up your reflective Coroplast signage.
- H-Stakes: Custom reflective Coroplast signs are often paired with H-stakes for ground placement. They slide directly over the flutes of the corrugated plastic for quick setup into soft earth.
- Spider Stake: It’s similar to H-stakes. The two upper sticks slide into the flutes of the plastic face. Press the plastic base into the earth until you have your signage firmly set up.
- Grommets: Order reflective corrugated signs with grommets if you need to install it on a fence or wall. This allows for secure fastening using zip ties and ropes.
- Zip Ties: You can use this accessory with grommeted reflective Coroplast. Pass them through the grommets and fasten the sign to the fence. Cut the excess for a neat look.
- Nylon Ropes: Installation with nylon ropes requires the same techniques as with zip ties. Pass them through the holes in the Coroplast and the fence. Tie them and cut for a neat look. You can melt the cut edges with a lighter to avoid fraying.
