Quick answer: For Corflute® safety signs, match the board to the sign type. Warning and caution signs (black on yellow) print best on yellow Corflute® with black-only artwork. Danger, prohibition, mandatory, emergency and fire signs use red, blue, green or white layouts, so print those in full colour on white Corflute®. Both come in 5mm Australian-made Corex board, cut to any size up to 2400 x 1200mm, with 1 business day production on smaller jobs.
Mediapoint is a trade-only printer in Derrimut, Melbourne. We print site safety signs on Corflute® for sign shops, print resellers, builders' signage suppliers and agencies, and blind-ship every job under your brand.
Yellow or white Corflute®: which board for which sign?
Australian workplace safety signs follow colour and shape conventions set out in AS 1319, the Australian Standard for safety signs in the occupational environment. Those colours decide which board gives the cleanest result.
| Sign type | Usual look | Board to order |
|---|---|---|
| Warning / caution | Yellow triangle, black border, black symbol and text | Yellow Corflute®, black-only artwork |
| Danger | Red, black and white | White Corflute®, full colour |
| Prohibition | Red circle and slash on white, black text | White Corflute®, full colour |
| Mandatory (PPE) | Blue circle, white symbol, black text | White Corflute®, full colour |
| Emergency information | Green background, white symbol and text | White Corflute®, full colour |
| Fire equipment | Red background, white symbol and text | White Corflute®, full colour |
The full breakdown of categories, symbol sizes and viewing distances is in our construction site signage guide.
Why yellow Corflute® suits warning signs
Yellow board gives you the high-vis background for free, so the print is just black text, symbols and borders. That keeps the job simple and economical, and black on yellow is the strongest contrast for warning and caution signs read from a distance.
There's one catch to explain to clients: we print yellow Corflute® in CMYK with no white ink. Every colour mixes with the yellow board underneath. Cyan, magenta and light tones look muted or shift colour, and anything meant to be white will show as yellow. Keep artwork to black text, symbols and simple graphics.
Typical yellow Corflute® jobs include caution and warning signs, temporary hazard notices, roadworks and event safety signs, and directional signs on site.
Why danger signs go on white Corflute®
A danger sign needs a true white panel with red and black. On yellow board there's no white to print, so the layout can't be reproduced. The same goes for prohibition, mandatory, emergency and fire signs, which all rely on white, or on clean reds, blues and greens. Print these on white Corflute® Print Only in full-colour UV.
If your client prefers recycled board, Corflute® Eco (50% recycled content) is an option. It has an off-white, lightly speckled look, so check the client is happy with that before you use it for crisp white-panel safety signs.
Sizes for Corflute® safety signs
Both boards are cut to any size up to a full 2400 x 1200mm sheet, in rectangles, circles and simple convex shapes with up to five points. Each job is one size, with multiple artworks allowed, so a set of warning signs in the same size can go through as one order.
Choose size by how far away the sign needs to be read. Bigger symbols and text are needed for longer viewing distances. Our standard Corflute® sign sizes guide covers the common sizes, including 600 x 900mm.
Flutes run along the 2400mm length. When your size fits either way, choosing Varied lets us mix flute directions to fit more signs per sheet and keep the cost down. If the signs must match, pick Horizontal or Vertical.
Fixing safety signs on site
- Temporary fencing: cable ties through eyelets are the usual method. Order Corflute® with Eyelets for white board signs that need holes fitted.
- Frames and stands: Print Only boards are supplied cut to size with no fittings, ready to frame, stake or fix.
- Footpaths and entries: Corflute® A-frames are a flat-pack option for movable signs.
- Windy sites: fix at every corner and don't rely on a single point. See our wind damage guide and eyelets and mounting hardware guide.
How long safety signs last outdoors
Expect around 12–24 months outdoors before fading shows, depending on UV exposure, installation and wind. Indoors they last much longer. Safety signs should stay legible for the life of the project, so check them regularly and replace faded ones. More detail is in our Corflute® durability guide.
Who is responsible for compliance?
The artwork makes a safety sign compliant, not the board. Your client is responsible for the sign wording, symbols, colours, sizing and any standards or WHS requirements their site has to meet. We print the artwork supplied and don't redesign or certify it. For site-specific questions, your client should talk to a qualified WHS adviser.
