Corflute signs: the tradie's guide to site signage
Sizes, costs, fixings and honest lifespan — everything to know before you order site boards.
Corflute is the workhorse of Australian building sites — the board behind every estate entrance sign, safety notice and sold sticker. Here's the straight guide from our Moorebank studio: what it actually is, which sizes matter, what it costs in 2026, and how long it honestly lasts nailed to a fence in Western Sydney sun.
What corflute actually is
- Fluted polypropylene. A plastic board with hollow channels running through it — that's the "flute". It weighs almost nothing, shrugs off rain, and prints beautifully flat on a flatbed press.
- Why tradies love it. It's the cheapest rigid sign per square metre, it takes a beating, and when a stage of the job ends you replace it without wincing.
- Where it shines. Anything site-based and temporary: entrance boards, safety notices, direction arrows, developer signage, open-home signs.
- Where it doesn't. A permanent, public-facing fascia isn't corflute territory — that's an ACM panel job, and our corflute vs ACM comparison covers the full trade-off.
The sizes that matter
| Size | Typical job | How it's fixed |
|---|---|---|
| A2 & A1 | Door-sized safety notices, induction info, neighbour notifications | Cable ties through the flutes |
| 600 × 900 mm | The site-notice standard: logo, trade, licence, phone | Star pickets or cable ties to fencing |
| 1200 × 900 mm | Entrance boards read from the street | Two star pickets, top and bottom |
| Custom, up to ~2.4 m | Estate hoardings and large developer signage | Frame or scaffold-mounted |
What corflute signs cost in 2026
A2 and A1 notices usually land in the tens of dollars each, not hundreds — the material is cheap, so the design and print do the talking.
The 600 × 900 and 1200 × 900 boards most sites want typically sit in the low-to-mid hundreds for a small set, depending on finishing and whether both sides print.
Estate and developer runs price per-unit far lower than single boards — pallet quantities make each sign close to disposable, which is exactly the point.
Every job is quoted exactly, design to delivery, once we know the size, quantity and number of sides. Ask for a small-run number and a bulk number side by side — the gap between them is usually the whole decision.
Where corflute wins (and where it doesn't)
Logo, trade, licence number, phone — read at 50 km/h on the way past. The sign most clients judge you on before they meet you.
PPE signage, out-of-hours works notices, induction boards — cheap enough to replace every stage without asking finance.
Land-release boards, "now selling" panels, direction arrows — volume-priced and refreshed as stages sell out.
Real-estate and weekend-event signs: light, cheap, effective — gone by Monday without regret.
Where it doesn't win: anything permanent and public. A corflute fascia bows and fades within a year or two; an ACM panel stays dead-flat for many. If the sign has to carry your name for the long haul, read the corflute vs ACM comparison before you spend.
Lifespan, fixings & what a site sign must carry
- Lifespan, honestly. In full Western Sydney sun, expect 12–18 months before UV fade and edge wear show. Under cover, or for jobs that end sooner, it looks sharp well past that — we print UV-stable inks, but no ink outlasts the sun forever, and that's why corflute is a temporary material.
- Fixings take 60 seconds. Star pickets for entrance boards, cable ties threaded through the flutes for temporary fencing, tek screws for timber — no brackets, no drill template.
- What the sign must carry. Logo, trade, licence number where it applies, and a phone number sized to be read at speed. The rule from our banner text-size guide applies: if a driver can't read it at 50 km/h, it's decoration.
- Double-sided is a gate decision. Boards read from two directions get double-sided printing — worth it at the main entrance, overkill on a side fence.
FAQs
Yes — we print in Moorebank and deliver across Sydney, including estates in Prestons, Warwick Farm and Oran Park. Give us the site address and most orders are ready within a few working days.
Yes — your artwork is kept on file, so reprints skip the setup cost and price on quantity alone. The more boards per run, the cheaper each one gets.
Both sides can be printed — standard for entrance boards read from two directions. Single-sided is the budget default; just say which you need when you ask for the quote.
Usually not for signs inside a private construction site, but the rules change on public land and in some zones. Our NSW signage rules guide covers the basics, and your council confirms anything placed on public land.
Getting the details right matters more than the material: our NSW signage rules guide covers what councils expect, and the trades & builders page shows full site-branding kits — utes, hi-vis and site boards together. We print and deliver corflute signs Sydney-wide from Moorebank, including the Prestons and Warwick Farm estates.
