Why choose Correx

100% waterproof

Polypropylene does not absorb water, so Correx boards will never swell, warp or go soft in wet weather.

Cost-effective in volume

Our lowest-cost rigid board, making it economical for kitting out building sites, road events or multi-branch promotions.

Lightweight and easy to fix

Light enough to carry in stacks and simple to attach with cable ties, screws or adhesive.

Direct UV print

UV inks printed straight onto the board give sharp text and bold colour with no vinyl layer to peel.

Where Correx boards are used

For property work see our ready-configured estate agent boards, and event signage for short-run display work.

Choosing between boards. Correx is the outdoor workhorse. Step up to 3mm ACM aluminium when the sign is permanent and needs to look premium, or across to 5mm foam board when it's an indoor display and print quality is what people will notice.

Frequently asked questions

How long will a Correx board last outdoors?

Correx is waterproof and unaffected by rain, so it handles the weather from day one. It is built for short- to medium-term outdoor work - site boards, campaigns, events and property boards. For a permanent installation that stays up for years, ACM aluminium is the better specification.

What size boards can you print?

Any size up to 2440 × 1220mm, which is a full sheet. Enter your exact dimensions in the configurator and the price recalculates as you type. Boards are cut square as standard, or to a shape you supply as a vector outline.

Can you print both sides?

Yes. Choose single or double sided in the configurator and the price updates. Double sided is worth it for boards seen from two directions - pavement signs, hanging boards and fence lines on a corner plot.

Do I have to supply finished artwork?

No. Upload a print-ready PDF, AI, EPS or SVG if you have one and we will check it before printing, or choose the design service and we will set the board out from your logo and a rough brief for a fixed artwork fee, shown in the configurator. Our artwork guide covers bleed, fonts and resolution.

Correx, foam board or ACM - which do I need?

Correx for outdoor signage on a budget, especially in quantity. Foam board for crisp indoor displays where the print quality shows. ACM aluminium for permanent outdoor signage that has to look sharp for years. If you are unsure, tell us where the board is going and we will advise.

How quickly can boards be printed?

Standard production is three to five working days. Delivery is chosen at checkout. See our turnaround and lead times page for the detail.
