Corflute Sheets: Uses, Types and How to Buy in Australia
Corflute sheets explained: what they are, where they work best, what to check before you buy, and how to order cut to size online in Australia. Get a price.
If you have ever seen a real estate sign, an election poster or a temporary site notice, you have almost certainly seen Corflute. It is one of the most recognisable plastic sheets in Australia, yet many buyers are not sure exactly what it is, how it differs from other plastic sheets, or what to check before ordering. This guide covers the essentials so you can choose with confidence and get the right sheet cut to your size.
What Corflute sheets actually are
Corflute is a trade name for twin-wall fluted polypropylene sheet. Two thin, flat skins are joined by a series of internal ribs running in one direction, which creates the hollow channels you can see along the cut edge. That structure gives the sheet a good stiffness to weight ratio, so it stays light and easy to handle while still holding a flat face for printing or mounting.
Because it is polypropylene, it also inherits the traits of that plastic: it resists moisture, is generally resistant to many everyday chemicals, and can be cut with simple tools.

Where Corflute works best
Corflute earns its popularity because it is economical, light and quick to work with. Common uses include:
Signage: real estate boards, site safety signs, directional signs, event and election signage.
Temporary protection: covering floors, benchtops, doors and finished surfaces during renovations and moves.
Packaging and dividers: reusable boxes, layer pads, separators and trays where a light, wipe-clean material is useful.
Displays and crafts: model making, backing boards, templates and short-run promotional pieces.
If your project is a retail or promotional display, it is worth comparing Corflute against more durable options. Our page on point of sale displays shows where acrylic and other materials suit longer-term, higher-end presentation, while Corflute remains a smart pick for short-run or changeable messaging.
What to check before you order
Flute direction
The flutes run in a single direction, and the sheet is noticeably stiffer across the flutes than along them in some situations, while it folds and bends more easily in one direction. For signs that stand up on stakes, the flutes usually need to run vertically so a stake can slide inside. For panels that must resist sagging across a span, orientation matters too. Tell us the direction you need when you place your order.
Thickness and sheet weight
Thicker or heavier-grade sheet resists dents and flexing better, which helps for larger signs exposed to wind. Thinner sheet suits temporary covers and lightweight packaging. Match the grade to the size of the panel and how long it needs to last, rather than defaulting to the cheapest option.
Colour and finish
Check the colour availability on the product page before you design your artwork. If you are printing, white is typically the go-to for strong contrast, and you should confirm that your print method is suitable for polypropylene, since inks do not always grip a low surface energy plastic without the right preparation.
Indoor or outdoor use
Corflute is routinely used outdoors for short to medium-term signage, but sunlight, wind and open flute ends all affect lifespan. For permanent outdoor installations, a solid sheet such as polycarbonate or acrylic is usually a better long-term investment.
Corflute vs other lightweight boards
Corflute is not the only light board on the market. If you want a flat, closed-cell polypropylene board without visible flutes, the Foamlite Uniboard ECO polypropylene sheet is worth a look for display and packaging work. For rigid, fabricated parts that need chemical resistance and long service life, a solid sheet is the better path, and our polypropylene sheet range covers that. If you are not sure which suits your job, describe the application to us and we will point you to the right one.
Cutting Corflute: DIY or cut to size?
Corflute can be cut with a sharp knife and straight edge, but results depend on a fresh blade and steady pressure. Dull blades crush the flutes and leave ragged edges, and cutting large panels accurately at home is slow. Ordering cut to size saves material, gives consistent edges and means your panels arrive ready to print, mount or install.

Getting the best result from your Corflute
A few simple habits make a real difference. Store sheets flat and away from direct heat so they do not warp. Keep the protective surface clean and dry before printing or applying vinyl. When using outdoors, orient open flute ends downward where possible so water drains rather than pooling. And for signs that will face strong wind, plan for a firm frame or extra stakes rather than relying on the sheet alone.
Choosing the right sheet for your project
Corflute is a practical, affordable choice when you need a light, printable and easily replaced panel. If your project calls for long-term durability, clarity or structural strength, a different plastic may serve you better, and it is worth confirming before you place a bulk order. The team at Perspex Online can help you weigh up the options based on your size, location and budget.
