A lightweight, corrugated plastic board made from polypropylene. It's strong, weather-resistant and the standard for temporary signs.

3.5mm is lighter and cheaper, fine for smaller signs and short-term use. 5mm is stiffer and stays flatter on bigger sizes and in strong wind.

Yes. Correx is waterproof and stands up to most weather, which is why it's used for site boards and roadside signs. Like any sign, long spells in direct sun can fade it gradually.

How long will a Correx sign last?

It's best for short to medium-term signs. It won't rust or rot and takes knocks well, though it can bend under heavy force. For a permanent sign, choose a more rigid board.

How do I put them up?

Choose drilled corners to fix them with cable ties, screws or nails. Undrilled boards can go on stakes through the flutes, in a frame or be stuck to a wall.

Where do the holes go?

Holes are 5mm wide, 30mm from the edges. If any side of the sign is under 400mm, they're 15mm from the edges. Keep important parts of your design clear of those spots.

Can I print both sides?

Yes. Choose Double Sided for signs seen from both directions, and send a 2-page PDF.

Is Correx recyclable?

Yes. It's PVC-free polypropylene and can be recycled where facilities are available.

Will you check my artwork?

Yes. File Check is free and selected by default: our prepress team check size, resolution and more, and contact you if anything needs fixing. If you'd rather we fixed the problems for you, choose File Assist. We'll resize, fix fonts and correct the layout for a flat fee. Nothing goes to print until the artwork is right.

Can I send my artwork later?

Yes. Place your order and email your artwork over when it's ready. Production starts once we have it.
