Corflute Signs in Merrylands & Parramatta

If you've driven past a house with a "For Sale" board out front, a construction site with a builder's name on the fence, or a school fete with directional signs pointing toward the car park, you've seen Corflute in action. It's the material behind most of the temporary signage you see day to day around Western Sydney, and there's a good reason it's stuck around as the go-to option for so long — it's light, cheap to produce in bulk, and holds up well enough outdoors to get the job done.

We print and supply Corflute signs for real estate agents, builders, schools, community groups and businesses across Merrylands, Parramatta and the surrounding suburbs. This page goes through what Corflute actually is, when it's the right choice, when it isn't, and the practical details — thickness, sizing, mounting — that matter once you're ready to order.

​

What Corflute Actually Is

​

Corflute is a corrugated plastic board, usually made from polypropylene, built in the same fluted structure as cardboard but using plastic instead of paper. That fluted core is sandwiched between two flat outer layers, giving the board rigidity while keeping it lightweight — a full sheet weighs a fraction of what an equivalent piece of timber or metal would.

The fluting runs in one direction through the board, which matters more than most people expect. A sign that's mounted or handled against the direction of the flute tends to bow or bend far more easily than one supported along it. It's a small detail, but it's one of the more common reasons a customer's DIY-mounted sign ends up warped within a few weeks.

​

How Corflute Is Manufactured

​

Corflute starts as extruded polypropylene, formed into the corrugated profile and laminated between two flat sheets in a continuous production process. The result is a board that's naturally weather resistant, since polypropylene doesn't absorb water the way cardboard or MDF would, and won't rust or corrode like a metal sign left out in the rain.

Printing happens after the board is formed, typically using UV printing directly onto the surface, or a printed vinyl overlay applied to a blank board. UV printing tends to give better results for full-colour designs and photographic imagery, and the ink cures instantly under UV light rather than needing to air dry, which is part of why turnaround on Corflute signs is usually fast.

​

Why Corflute Is Still the Go-To Material for Temporary Signage

​

There are more durable signage materials available — ACM, aluminium, acrylic — and we work with all of them. But Corflute earns its place for a specific reason: it's the most cost-effective option for signage that's genuinely temporary, or needed in volume.

A real estate agency running twenty open homes a month doesn't need twenty aluminium signs. A builder wanting site identification for the six months of a project doesn't need a sign built to last fifteen years. An election campaign putting up boards across an entire electorate needs hundreds of signs at a price that makes sense per unit. Corflute fits all three of those situations in a way that heavier, more expensive materials simply don't.

​

Benefits and Limitations

​

Where Corflute performs well:

• Genuinely lightweight, making it easy to install, move and store

• Cost-effective in both small runs and bulk orders

• Naturally water resistant, since it's plastic rather than cardboard-based

• Fast to print and produce, which suits time-sensitive jobs

• Holds full-colour printing well, including detailed photography and branding

Where it falls short:

• Not built for long-term permanent installation — UV exposure over a year or two will eventually fade colours and weaken the board

• More vulnerable to wind than rigid materials, particularly on larger sign faces

• Can be punctured or dented by impact, unlike aluminium or ACM

• Not the right choice for anything needing a premium, polished appearance — for that, we'd usually point customers toward ACM or acrylic shopfront signage instead

Being upfront about those limitations matters. We'd rather tell a customer that Corflute isn't the right fit for a permanent building sign than sell them something that looks tired within twelve months.

​

Indoor vs Outdoor Use

​

Corflute works in both settings, but the demands are different. Indoor signage — trade show boards, retail point-of-sale, school event signs — doesn't face UV or moisture exposure, so a standard board and standard print will hold its colour and condition for a long time simply sitting inside.

Outdoor use is where thickness, ink choice and mounting method all start to matter. UV printed ink resists fading better than standard printed vinyl overlays exposed to direct sun, and thicker board handles wind loading and general knocks better than the thinner options often used for short indoor runs.

​

Single-Sided vs Double-Sided Printing

​

Single-sided printing suits signage that's only viewed from one direction — a sign fixed flat against a fence or wall, for example. Double-sided printing is worth the small extra cost for anything free-standing or viewed from both directions, like an open home sign on a nature strip that traffic passes in both directions, or an A-frame style sign near a shopfront. It's a detail that's easy to overlook when ordering and mildly frustrating to discover afterward, so it's worth specifying clearly at the point of order.

​

Thickness Options

​

Corflute is commonly available in a few standard thicknesses, and the right one depends on the sign's size and how it'll be used.

ThicknessTypical Use

2mmSmall signs, short-term indoor use, budget-conscious short runs

3mmThe most common general-purpose thickness — real estate, open home, event signage

5mmLarger boards, construction site signage, anything needing extra rigidity

7mm+Heavy-duty applications, large freestanding signs, higher wind exposure sites

As a general rule, the larger the sign face, the thicker the board needs to be to avoid flexing and warping, particularly if it's going to be exposed to wind. A 3mm board might be perfectly fine for a standard open home sign but genuinely undersized for a large construction hoarding panel.

​

Common Sizes and Custom Sizing

​

Standard sizes cover most needs — common formats include 600 x 450mm (a typical real estate yard sign size), 900 x 600mm, and full sheet sizes around 2400 x 1200mm for larger applications like construction site boards. That said, custom sizing is straightforward to produce, and a lot of our orders are cut to specific dimensions for a particular fence panel, sign frame or site requirement rather than a standard off-the-shelf size.

​

Eyelets, Cable Ties and Mounting Hardware

​

How a Corflute sign is going to be mounted should be decided before it goes to print, not worked out afterward. Common mounting methods include:

• Eyelets — metal-reinforced holes punched around the sign's edge, used for tying or hanging the sign to fencing, mesh or a frame

• Cable ties — the simplest method for attaching a sign with eyelets to chain wire fencing or scaffolding, widely used on construction sites

• Metal H-stakes — a step-in metal frame that the sign slots into, commonly used for real estate and open home signs placed directly into the ground

• Direct screw or bracket mounting — used where a sign is fixed to a solid surface rather than fencing or a stake

Getting eyelet placement right matters more than people expect — eyelets positioned too close to a corner or too far apart for the mounting surface can lead to a sign tearing or flapping loose in wind, which defeats the purpose of putting it up in the first place.

​

Installation Methods

​

Most Corflute signage is designed for simple, tool-free or low-tool installation, which is part of the appeal for time-poor customers. Real estate signs generally slot into H-stakes pushed directly into the ground. Construction site signage is usually cable-tied to existing site fencing. Event and directional signage often uses a combination of stakes and cable ties depending on the surface available on the day.

For anything larger or in a high-wind location, we'll talk through mounting options at the order stage rather than leaving it to guesswork on installation day — a sign that's correctly sized but poorly mounted will still fail early.

​

Expected Lifespan and Weather Resistance

​

Realistically, a Corflute sign in reasonable outdoor conditions lasts somewhere in the range of a few months to around two years, depending on thickness, ink type and sun exposure. Signs facing full western sun in a Western Sydney summer will fade and weaken faster than a sign in a shaded or south-facing position. This isn't a flaw in the product — it's simply the nature of the material, and it's exactly why Corflute is priced and used the way it is. If you need something to look the same in five years' time, Corflute was never the right material for that job.

​

UV Printing and Fade Resistance

​

UV-cured ink sits on the surface and cures instantly, giving sharper, more durable colour than solvent-based alternatives that soak into the board. It's not fade-proof — no printed outdoor material genuinely is — but it noticeably extends how long a sign looks presentable compared to lower-grade printing methods, which is worth asking about if you're comparing quotes and one price seems significantly cheaper than another.

​

Artwork Preparation and the Printing Process

​

We can work from print-ready artwork if you've already got a design prepared, or build the artwork from scratch based on your branding, logo and the information the sign needs to communicate — agent details for a real estate sign, site contact information for a construction board, or event details for a temporary directional sign. Once artwork is approved, printing itself is fast, which is one of Corflute's practical advantages over materials requiring longer manufacturing or curing time.

​

Bulk Orders, Short Runs and Turnaround

​

Corflute suits both ends of the order spectrum. A single one-off sign for a small business event is entirely reasonable to order, and so is a bulk run of several hundred identical boards for an election campaign or a franchise rolling out consistent signage across multiple sites. Because the printing and cutting process is efficient, turnaround on Corflute is generally faster than more involved signage products, which matters when a listing needs a sign by the weekend or a site needs identification before an inspection.

​

Finishes

​

Beyond standard gloss or matte print finishes, Corflute can be supplied with rounded corners (useful for signs that'll be handled frequently), pre-drilled or eyelet-finished edges, and cut to irregular shapes rather than only standard rectangles, depending on the application.

​

Industries and Common Uses

​

Corflute's biggest strength is versatility, which is why it turns up across such a wide range of industries.

• Real estate — For Sale, Auction, Open Home and Sold boards are probably the most recognisable use of Corflute anywhere, and agents across Parramatta and Merrylands typically order these in volume given how frequently listings turn over.

• Construction and builders — site identification boards, safety signage, and builder branding on hoarding fences are standard on almost every active site.

• Developers — larger format development signage announcing a project, often combined with render imagery and contact details for expressions of interest.

• Retail — short-term promotional signage, sale announcements, and in-store directional signs.

• Events — sponsor boards, directional signage guiding attendees around a venue, and temporary branding for one-off events.

• Schools — fete and event signage, sports day directional boards, and fundraising promotion.

• Political campaigns — election signage produced in bulk across a electorate, typically on a tight timeline once a campaign period opens.

• Community organisations — event promotion, fundraising drives, and general notice boards for markets and local gatherings.

• Trades — job site branding and simple advertising boards for tradies working across multiple sites.

• Warehouses, manufacturing and industrial businesses — site signage, safety notices, and temporary way-finding around larger industrial sites in areas like Smithfield and Fairfield.

 

Practical Advice: Choosing the Right Thickness

​

If you're not sure what thickness to order, a rough guide: standard real estate and open home signage is well served by 3mm board. Anything larger than a metre across, or going somewhere genuinely exposed to wind — an open block, a corner site, near a main road — benefits from stepping up to 5mm. If you're ordering a large construction hoarding panel or something that needs to survive an entire building project, 5mm or heavier is worth the small extra cost over 3mm.

​

When Corflute Is the Wrong Choice

​

Being honest about this matters more than upselling every job. Corflute isn't the right material when:

• The sign needs to look presentable for several years without replacement — ACM or aluminium is a better long-term investment

• It's a permanent shopfront or building sign — this is a job for proper shopfront signage materials, not temporary board

• The sign will be handled or moved constantly — Corflute dents and creases more easily than more rigid materials

• Presentation needs to be premium, such as a reception or office environment — acrylic or fabricated lettering reads as considerably more professional

We'd rather point a customer toward the right product for their situation than sell Corflute into a job it's not suited for, since a sign that fails or looks poor within a few months reflects on us as much as it does on the customer's business.

​

How to Maximise Lifespan

​

• Choose a thickness suited to the sign's actual size and exposure, not just the cheapest option

• Use UV printing rather than standard print for anything facing direct sun

• Mount using eyelets and stakes appropriate to the site, rather than improvised tape or wire

• Avoid leaning signs against surfaces where wind can catch and flex the board repeatedly

• Store unused signs flat, indoors and out of direct sun between uses if they're being reused for multiple listings or events

 

Storage, Cleaning and Reuse

​

Corflute signs can absolutely be reused, particularly for real estate agents running similar Open Home or For Sale boards across multiple listings. Storing boards flat rather than leaning them against a wall reduces long-term warping, and keeping them out of direct sun when not in use noticeably extends how long the print stays vibrant. Cleaning is straightforward — a damp cloth and mild detergent is usually enough to remove dirt or dust without damaging the print surface.

​

Wind Considerations

​

Wind is the most common reason a Corflute sign fails early, particularly for freestanding signs on H-stakes. Larger sign faces catch more wind, which is exactly why thickness matters so much for bigger boards. On exposed sites, we'll sometimes recommend additional stakes, lower sign height, or a thicker board specifically to account for wind loading, rather than a customer finding their sign on the ground the morning after a windy night.

​

Frequently Asked Questions

​

How long do Corflute signs last?

 

Typically a few months up to around two years outdoors, depending on thickness, ink type and how much direct sun exposure the sign gets. Indoor signage lasts considerably longer since it isn't exposed to UV or weather.

​

Are Corflute signs waterproof?

​

Yes, the polypropylene material itself is naturally water resistant and won't absorb moisture or degrade like cardboard. Extended exposure to sun is a bigger factor in a sign's lifespan than rain.

​

Can Corflute signs be reused?

 

Yes, particularly for real estate and event signage that gets used repeatedly. Storing boards flat and out of direct sun between uses helps them stay in good condition for multiple uses.

​

What thickness should I choose?

 

3mm suits most standard signage like real estate boards. Larger signs, or anything in an exposed, windy location, are better served by 5mm or heavier board.

​

Can you print both sides?

​

Yes, double-sided printing is available and recommended for any freestanding sign viewed from more than one direction, such as an open home sign on a nature strip.

​

Can I order just one sign?

 

Yes, single sign orders are entirely normal alongside our bulk printing work. There's no minimum order requirement that rules out a one-off job.

​

Do Corflute signs fade?

 

All printed outdoor signage fades eventually with UV exposure. UV-cured printing significantly slows this down compared to standard printing, but no outdoor Corflute sign is fade-proof indefinitely.

​

Can they be mounted to fences?

 

Yes, this is one of the most common mounting methods, typically using eyelets and cable ties to attach the sign to chain wire or mesh fencing on construction sites.

​

Can you design the artwork?

 

Yes, we can design from scratch using your branding and the information you need on the sign, or work from print-ready artwork if you've already got a design prepared.

​

How quickly can they be printed?

 

Corflute has one of the faster turnaround times of any signage product we offer, since printing and cutting is a relatively quick process once artwork is approved. Exact timing depends on quantity and current workload, so it's worth asking when you enquire, especially for time-sensitive listings or campaigns.
