The weatherproof workhorse

4mm fluted coroplast is light, rigid and fully waterproof — the go-to for short-to-mid-term outdoor signage.

Mounted & cut

We print vinyl, mount it and cut to size; laminate for durability or eco to save.

Checked before it prints

Every file runs through pre-press QA — bleed, resolution and color — before anything runs.

Coroplast Signs · questions

Before you order.

Which substrate is right for my sign?

Coroplast is the cheap, light, fully-weatherproof pick for yard signs and short outdoor runs. PVC (Sintra) is rigid and moisture-proof for medium-term exterior signs. Foam board and Gatorboard are interior display boards — Gatorboard is the stiffer, warp-resistant one for large panels.

Do coroplast signs include ground stakes?

H-stakes (the wire ground stakes) are an inexpensive add-on — tell us the quantity in your order notes and we'll include them. The sign price covers the printed, cut, ready-to-mount panel.

What's the biggest rigid panel you make?

We print up to 4 ft on the short side in-house and mount to the substrate from there — larger graphics are produced in seamed panels. Need something oversized or in aluminum/Dibond? Use 'Request a quote' and we'll route it through our large-format partner.
