Order any size from 12″ × 12″ up to 48″ × 96″ online, from $12.96 for an 18″ × 24″ sign, printed in 3 to 5 business days after proof approval.
What Are Coroplast Signs?
Coroplast is corrugated polypropylene: two flat plastic walls joined by a hollow, fluted core. It is built like corrugated cardboard, but it is waterproof, much stronger and light enough to carry and install by hand. Our standard sheets are white and 4mm thick, printed in full colour. Coroplast is an affordable choice for short- and medium-term outdoor signs in Calgary’s climate, typically lasting 6 months to 2 years outdoors.
Common Uses for Coroplast Signs
Real Estate Signs
Coroplast is popular for commercial real estate, usually as 48″ × 48″ or 48″ × 96″ signs for spaces for lease, subleases and buildings for sale. Because coroplast costs less than other rigid sign materials, it is easy to replace or update a listing. See our commercial real estate signs.
Construction and Contractor Signs
Contractors use coroplast for safety signage (hard hats, safety vests and steel-toed boots required), for project and development notices that tell the public what is happening on a property and who to contact, and to advertise the general contractor and subcontractors on site. To brand construction fencing, pair your signs with mesh vinyl banners, and keep site paperwork organised with carbonless NCR safety forms.
Election and Campaign Signs
Coroplast is inexpensive, quick to produce in large runs and recyclable after the campaign. For busy roads, we recommend 48″ × 96″ signs mounted on a 4×4 post frame so your message stays visible for the whole campaign. For yards, smaller signs on wire H-stakes work well; stakes are available with our lawn signs.
Events and Directional Signs
Coroplast is a lightweight, low-cost option for event wayfinding, parking and directional signs, and promotions.

Coroplast vs Alupanel: Which Sign Do You Need?
- Coroplast: lightweight corrugated plastic that costs less and suits short-term signs, such as lawn signs, elections, events, promotions and real estate listings.
- Alupanel: a rigid aluminum composite panel for permanent and long-term signs, such as storefronts, building-mounted panels, safety and wayfinding signs. See our alupanel signs.
