Corflute Signs Pricing: Complete Guide for AU Sign Shops

Why Is Corflute Pricing Harder Than It Looks?

Corflute looks simple. A flat sheet of fluted polypropylene, digitally printed, cut to size, maybe a couple of holes punched for a stake. How hard can it be to price?

Hard enough that most shops get it wrong - in both directions. Some quote so low they lose money on every election run that comes through. Others quote so high they never get past the first email reply from a property developer asking for 200 site boards.

The reason is that corflute spans an enormous range of jobs. A single bespoke 600x450mm real estate board and a 5,000-unit screen-printed election order are both "corflute signs" - but the cost structures have almost nothing in common. The same shop, using the same material, can have raw production costs that vary from $25/sqm to under $4/sqm depending entirely on how the job is set up and run.

A flat $/sqm rate averages all of that into one number. On small runs you'll be too cheap and lose money. On large runs you'll be too expensive and lose the work. Either way, you're guessing.

Here's how to calculate it properly - from first principles, not fudge factors.

What Is Corflute?

Corflute is a brand-agnostic Australian name for fluted polypropylene sheet. You'll also see it sold as Coroplast (the original US brand name), Correx (UK), or just "fluted PP" on technical spec sheets. Across the industry, "corflute" is the common term regardless of the actual manufacturer.

Structurally, it looks like plastic cardboard - two flat outer skins with internal flutes running in one direction, all extruded as a single sheet. The flutes give it rigidity along one axis (parallel to the flutes) and let it flex along the other. It's lightweight, weather-resistant for 1-5 years outdoors depending on UV stabilisers, and cheap enough to be effectively disposable for short-life applications.

It accepts digital UV-curable inks directly on the surface, takes adhesive vinyl well, and at high volumes can be screen-printed. It cuts on CNC routers, die-cutters, guillotines, and even sharp utility knives. There's almost no Australian sign shop that doesn't run corflute through its workflow somewhere.

Australian Sheet Sizes

Corflute comes in a small number of standard sheet sizes from Australian distributors:

Your nesting efficiency depends heavily on which sheet you start from. A 600x450mm sign nests perfectly four-up on a 1200x900 sheet (near 100% yield) but only six-up on a 2400x1200 with an awkward offcut, depending on bleed and trim allowances. Picking the wrong starting sheet adds 10-20% to your material cost without changing anything visible to the customer.

Thicknesses and Use Cases

5mm is the workhorse of Australian corflute. It's stiff enough to handle wind on a timber stake, light enough to ship hundreds in a pallet without crushing, and the most cost-effective for double-sided print runs. If you're stocking one thickness, stock 5mm.

Flute Orientation Matters

The internal flutes run in one direction only. That direction affects two things:

1. Rigidity - the sheet is much stiffer along the flute axis than across it. A horizontal-flute real estate board sags less along its width. A vertical-flute stake sign resists bending around the stake.
2. Mounting - stake-inserted signs require vertical flutes so the stake slides up inside the flute channel. Order vertical-flute sheets specifically if you're producing stake signs, or order standard sheets and cut them so the flutes end up vertical on the finished sign.

If you're cutting signs from a master sheet, the orientation determines which dimension the flutes run with - which in turn determines whether you can fit four-up, six-up, or eight-up on the sheet without compromising the finished product. This is one of the variables most shops never explicitly calculate, and it's a hidden source of waste.

What Print Methods Are Used for Corflute?

The choice of print method is one of the biggest cost levers in corflute pricing, and it changes with volume.

Digital Direct (Flatbed UV)

Most Australian sign shops with a flatbed UV printer print corflute directly. The sheet sits on the bed, the print heads pass over it, and the UV ink cures instantly. Suitable for any quantity from one-off to several hundred per design. Print time scales linearly with area - 50 boards take roughly 50 times as long as one board, minus a small setup saving.

This is the default for short-run real estate, event signs, A-frame inserts, and any job under about 500 units of a single design.

Vinyl Applied

Print on adhesive vinyl, then apply to the corflute. Used when:

• The print quality requirements exceed what the flatbed can deliver
• The shop doesn't own a flatbed and prints SAV on a roll printer instead
• Reusable corflute substrates (frequent updates) make removable vinyl economical

The cost stack is different - you're paying for vinyl material, lamination if needed, application labour, and the corflute substrate underneath. Often more expensive than direct flatbed, but sometimes unavoidable.

Screen Print

Once you're past about 500-1,000 units of a single design, screen printing becomes the cheapest option per unit. Screen setup costs (making the screens, registering them, colour matching) are high - typically $80-200 per colour per design - but the per-unit print cost drops dramatically. At 5,000 election signs with a two-colour design, screen print might cost 50-70% less per unit than digital direct.

The breakpoint where screen overtakes digital depends on your shop's hourly rates and screen setup costs. Most Australian shops cross over somewhere between 500 and 1,500 units per design.

Single vs Double-Sided

A double-sided print isn't twice the cost of single-sided - but it's close. You're paying for:

• Double the ink coverage
• Double the print time (or two passes)
• A flip step (manual or automated) between sides
• Sometimes a second pass through any laminator or trim line

Treating double-sided as a fixed 20% surcharge or a flat additive is wrong in both directions. On a small one-off, the flip and setup time dominate, so double-sided costs maybe 1.6-1.7x single-sided. On large runs where the setup is amortised, double-sided approaches 1.9x. Calculate it from real production time, not a rule of thumb.

What Are Corflute Signs Actually Used For in Australia?

Corflute applications fall into a handful of categories that each have distinct pricing characteristics.

Real Estate Boards

Typically 4mm or 5mm, 600x450mm or 600x900mm, double-sided print. Two common finishing approaches:

• Hemmed and eyeleted - corners punched with brass eyelets, sometimes with a fabric or vinyl hem applied to the top and bottom. Used for fence-mounted "For Sale" and "For Lease" boards.
• Stake-inserted - vertical flutes, no hardware on the corflute itself, supplied with a separate timber or steel H-stake that slides up inside the flutes.

Real estate is steady volume across the year, low individual order quantities (1-20 boards typical), and price-competitive. Margin comes from speed of quote, fast turnaround, and reliable supply.

Election Signs

The corflute job most shops fear and love. Volume is enormous - federal elections produce orders of 1,000-10,000+ signs per candidate, often across multiple seats. Almost always:

• 5mm corflute
• Double-sided print
• Vertical flutes for stake mounting
• Tight delivery window (typically 4-8 weeks before polling day)
• Multiple SKUs per order (different candidates, different messages, different seat-level branding)

This is where the difference between digital and screen print matters enormously - and where bulk multi-artwork production files separate good shops from great ones.

Construction Site Signs

Site safety signs, project signage, hoarding panels. Usually 5mm or 10mm depending on size and life expectancy. Often eyeleted, sometimes mounted to timber frames. Low artistic content (mostly text and standard safety pictograms) but high finishing requirements.

Event and Wayfinding

3mm or 4mm corflute, short-life applications, often single-sided. Low cost per unit, lots of SKUs, fast turnaround. Where shops make money is being able to quote 50 different signs across an event without spending three days putting the quote together.

Safety and Compliance Signs

Standard regulatory signs (mandatory PPE, hazard warnings, statutory notices) at bulk volumes for industrial customers. Often:

• 5mm corflute
• Eyeleted or holed for fixing
• Multiple SKUs per order (a 200-unit order might have 30 different artwork files)
• Single-sided print

The bulk multi-artwork structure is where automated quoting earns its keep. A 30-SKU order priced manually takes hours. Priced from a configurator, it takes seconds.

A-Frame Inserts

The corflute insert that slides into a metal or plastic A-frame. Usually 5mm, single or double-sided. Replaceable, often re-ordered as designs change. Lower margin individually but high lifetime value with repeat customers.

What Are the Cost Components of a Corflute Sign?

Like all manufactured products, corflute pricing decomposes into a small number of calculable components. None of them are magical - they're all measurable from your actual shop data.

1. Sheet Material

Cost per square metre of the corflute itself, varying with thickness:

Your actual cost per sign depends on yield - how many signs you cut from a sheet. A 600x450mm sign on a 1200x900 sheet (four-up, near 100% yield) costs roughly a quarter of the sheet. The same sign cut from a 2400x1200 sheet at six-up (with offcuts) costs a sixth of the sheet plus a share of the waste. Real cost per sign requires knowing the actual nesting, not just the finished area.

2. Print

Cost of laying ink on the substrate. Depends on:

• Print method (digital direct, vinyl applied, screen print)
• Coverage (light text vs full-bleed photographic)
• Single vs double-sided
• Print mode (quality vs speed trade-off on flatbeds)

Digital direct on a flatbed UV printer typically costs $8-18/sqm in machine time plus ink, before labour. Screen print at volume drops below $2/sqm per colour at the per-unit level once setup is amortised. For a deeper breakdown of how print cost is calculated, see our wide format printing pricing guide.

3. Cutting

How the sheet gets cut to finished size. Three main methods:

• CNC router - flexible, handles complex shapes, fast on volume, slower setup. Typical for stake holes, custom outlines, multi-artwork production sheets. See our CNC routing guide for the full breakdown.
• Die-cut - very fast per cut, high tooling cost, only economical for high-volume repeat designs. Used for some real estate boards and election signs.
• Guillotine - cheapest for straight rectangular cuts, fastest on simple shapes, no holes or curves. Used for basic rectangular signs.

Cutting cost varies from a few cents per sign on guillotine-cut bulk runs to several dollars per sign on complex CNC-cut shapes.

4. Finishing

This is where many shops lose money by under-quoting:

• Stake holes - punched, drilled, or CNC-routed. Time per sign varies from seconds (punched) to a minute or more (CNC routed with precision).
• Eyelets - brass eyelets in each corner. Labour-intensive on small runs (manual press) but fast on volume with pneumatic tooling.
• Hemming - applying a fabric or vinyl hem to top and bottom edges. Significant labour cost, often more than print itself on small runs.
• Edge trim - cleaning up the cut edge to remove flute fragments and burrs.

These costs disappear into the margin if you're not tracking them. They're not enormous individually but they add up - and on a 1,000-unit run, a 30-second finishing step that wasn't priced costs you a hundred-plus dollars of unpaid labour.

5. Hardware

Timber stakes (typically 1200mm long, pointed at one end), steel H-stakes, ground spikes. Eyelets and hemming tape. Cable ties for fence mounting. Shrink-wrap or plastic bags for packaging.

Hardware costs scale linearly with volume and are non-negotiable - if you forget them in the quote, they come straight out of margin. They're a particularly common omission when shops give "the corflute price" without itemising what comes with it.

6. Packaging and Freight

Corflute is bulky relative to its value. A pallet of 5,000 election signs is several cubic metres, takes time to wrap and palletise, and ships at significant freight cost. Packaging and freight are not afterthoughts - on high-volume orders they can equal the cost of the signs themselves.

Volume Tiers: Where Real Economies of Scale Actually Kick In

"10% off for 10, 20% off for 100" is a marketing line, not a cost calculation. Real economies of scale on corflute come from four specific mechanisms:

1. Setup amortisation - the fixed costs of any job (file prep, RIP setup, material handling, print calibration, machine loading) spread across more units.
2. Nesting efficiency - more units per design (and especially across designs) allow better yield from each sheet, dropping material cost per unit.
3. Print method change - at high enough volumes, screen print becomes cheaper than digital direct.
4. Hardware and consumables bulk pricing - stakes, eyelets, packaging all drop in unit cost at trade quantities.

The tiers where these mechanisms actually shift the cost structure look roughly like this:

The drops aren't smooth. They cluster around the points where a production method actually changes - and a customer asking for 1,500 units doesn't necessarily get a meaningfully better price than 800 units unless you're hitting one of those mechanism shifts.

This is one of the places where "first principles" pricing diverges most sharply from "x% off at quantity y" pricing. A pricing engine that calculates from the actual production process knows when 1,500 units moves you into screen print, when nesting efficiency improves, and when bulk hardware kicks in. A flat discount table doesn't.

Worked Example: 50x Real Estate Boards

Let's price a real job: 50x real estate boards, 600x450mm, 5mm corflute, double-sided print, four eyelets in corners.

Sheet material:

Print (digital direct UV, double-sided):

Cutting:

Finishing:

Other:

Final pricing:

That's around $29 per board for a 50-unit double-sided real estate run with eyelets. A shop quoting a flat $15/sqm "corflute price" would arrive at $4 per board on the print area alone - not even covering material - and then have to add finishing and hardware on top with no methodology, usually undercharging by 30-50%.

A shop quoting a flat $40 per board (because that's what one-offs cost) would lose the work to anyone doing the maths properly.

Bulk Multi-Artwork Orders: Where the Hard Stuff Lives

Election runs and bulk safety sign orders share a structural challenge that single-design jobs don't have: many SKUs in a single order.

An election order might include:

• 3,000 corflute signs for Candidate A's main seat
• 1,500 signs for the same candidate in a different seat with different artwork
• 500 smaller signs for letterbox drops
• 200 large hoarding panels for major intersections

A bulk safety sign order might be:

• 50 mandatory PPE signs (10 different artworks, 5 each)
• 30 hazard warning signs (8 different artworks, varying quantities)
• 20 site-specific custom signs (each one unique)

In both cases, the production workflow benefits massively from being able to consolidate the entire order into a single production sequence - one set of print runs, one nesting pass across all artworks, one finishing flow. The shops that can do this profitably are the ones that have either invested in production planning systems or that use software that handles it automatically.

This is one of the deliberate strengths SSQ was built for. Bulk multi-artwork orders get consolidated into a single production file with cross-job nesting handled automatically. Our test suite includes specific scenarios for single-artwork, multi-artwork (3 orders), bulk safety SKUs (25 artworks in one order), mixed sizes, oversized jobs, and orientation-mixed jobs - all on corflute. The algorithm has been running in production since early 2019, now on Version 5, and has been validated against real shop production data across all of these scenarios.

SSQ calculates optimal nesting layouts to maximise sheet utilisation across orders - including across multiple artworks in a single production run. The outcome: better sheet yield, lower material cost per unit, and a single production file that goes straight to the cutter without a designer manually laying out 25 different artworks.

This is the "we do the hard stuff" angle. Most quoting tools can price a single corflute sign. Almost none can price a 25-SKU safety order or a 5,000-unit multi-seat election run from a single configurator, in under a second, with production-ready files coming out the other end.

What Are the Most Common Corflute Pricing Mistakes?

Flat $/sqm Across All Variables

Quoting "$X per sqm" for corflute ignores thickness, double-sided, finishing, hardware, and quantity. A 3mm event sign and a 10mm hoarding panel are not the same product. Pricing them at the same rate guarantees you're wrong on one of them.

Break your corflute pricing into the actual variables: thickness, single/double-sided, print method, finishing options, hardware, and quantity. Calculate each from its real cost driver.

Ignoring Nesting at Volume

A shop running corflute on a one-sheet-at-a-time basis is paying full sheet cost for every job, regardless of what else is being printed that day. Shops that nest multiple jobs across sheets - especially across customers - drop material cost dramatically at any volume above small runs.

Manual nesting is time-consuming and error-prone. Automated nesting (or automated production planning that schedules jobs to share sheets) is one of the most direct ways to improve corflute margin without changing your customer-facing pricing at all.

Not Pricing Finishing as a Line Item

Stake holes, eyelets, hemming, and edge trim each cost time. Treating them as "included" gives them away. Treating them as a flat $5 add-on misses the variation between manual eyeleting (slow) and pneumatic eyeleting (fast), between two stake holes (cheap) and four (more expensive), between a clean guillotine edge (no trim needed) and a CNC cut edge (trim needed).

Itemise finishing as separate sub-product components. Customers can see what they're paying for, and you can vary the price legitimately based on real cost differences.

Equal Pricing for Single and Double-Sided

A double-sided corflute sign isn't 10% more than single-sided. It's closer to 70-90% more on the print component alone, before the additional handling time. Shops that quote a flat surcharge (or don't differentiate at all) are subsidising double-sided customers at the expense of single-sided ones.

Not Knowing Real Machine Throughput per Thickness

The flatbed prints 5mm and 10mm corflute at different speeds (head clearance, vacuum hold-down, sheet stability). If you're using a single sqm/hr number across all thicknesses, your machine time cost is wrong on at least one of them. Measure throughput per material and thickness combination. Your RIP software likely reports it - use that data.

Arbitrary Quantity Discounts

"10% off for 10, 20% off for 100, 30% off for 1,000" sounds reasonable but isn't grounded in your cost structure. Your actual cost drop from 1 to 10 might be 40% (setup amortises fast). Your cost drop from 100 to 1,000 might be 10% (because you're still on the same print method). Your cost drop at 1,500 might suddenly be 25% because that's where screen print becomes viable.

Quantity discounts should reflect real economies of scale, not arbitrary percentage steps. If you can't explain why each break is where it is, the breaks are guesses.

How to Improve Your Corflute Pricing Today

1. Separate by thickness - have distinct per-sqm rates for 3mm, 4mm, 5mm, and 10mm. The cost difference is real and should flow through to pricing.
2. Price single and double-sided as different products - not as a flat add-on. The print time and handling difference is significant.
3. Itemise finishing - eyelets, stake holes, hemming, edge trim each as separate line items with measured time and cost.
4. Track nesting yield - know how many signs you get per sheet for each finished size. That data is your real material cost per sign.
5. Set quantity breaks at real economies-of-scale points - around 10, 100, 1,000, and 5,000 units, where production mechanisms actually change.
6. Charge hardware as a separate line - timber stakes, H-stakes, eyelets, hemming tape. Don't bundle them invisibly into the corflute price.

Or, let the software handle it. SwiftSignQuote calculates corflute pricing from first principles - sheet material with real nesting yield, print cost by method and coverage, machine time at your actual throughput per thickness, finishing as itemised sub-product components, hardware at real bulk-pricing tiers, packaging and overhead included. Every variable that affects cost is calculated, not estimated. No fudge factors.

When you add a new thickness, define its cost parameters once and the pricing works across every dimension and quantity. When your sheet supplier changes prices, you update one number and every corflute product recalculates. Your customers get instant pricing on your website - embedded directly into your existing platform (Shopify, WooCommerce, WordPress, Squarespace, or any other) - configured to their exact specifications, priced from your actual costs, available 24/7.

SSQ handles the bulk multi-artwork case that breaks most quoting tools. A 25-SKU safety sign order or a 5,000-unit election run consolidates into a single production file with cross-job nesting outcomes that improve sheet yield - turning what would be hours of manual quoting and file preparation into a customer-facing configurator that returns a price in under a second and produces ready-to-cut production files after checkout.

We follow the Toyota principle: automation should free your team to focus on production, design, and customer relationships - not on repetitive quoting and file prep. SSQ automates the boring, repetitive parts of the corflute workflow so the skilled people in your shop - whether you run a sign shop, a CNC fabrication business, or both - spend their time on the work only they can do.
