Global procurement managers often face a challenge. You receive a site request for “Corflute” in Sydney. The next day, a team in Texas asks for “Coroplast.”
Are they the same material? Do they require different hardware?
Terminology confusion leads to ordering errors. It causes compliance risks. Optraffic clarifies the industry jargon in this guide. We help you distinguish between Corflute, Coroplast, and Correx so you can procure the correct corrugated plastic signage for any region.
What is Corrugated Plastic Signage? (The Science)
Let’s start with the chemistry.
Corflute, Coroplast, and Correx are essentially the same material. They are all popular trade names for twin-wall corrugated plastic signage (specifically, fluted polypropylene).
Think of it like tissues. You might ask for a “Kleenex” in the US or a “Tempo” in Germany. You are asking for the exact same product.
Technical Specifications (Universal):
- Material: High-Impact Polypropylene Copolymer.
- Structure: Two flat plastic sheets connected by vertical ribs (flutes).
- Properties: Lightweight, waterproof, chemical-resistant, and 100% recyclable.
If the chemistry is the same, why does the name matter? Because the name dictates the local hardware standards.
H2: Regional Differences in Corrugated Plastic Signage
Using the local term ensures you get the correct specifications (thickness and mounting style).
Australia & NZ: Corflute Signs (5mm & Box Edge)
In the Southern Hemisphere, the industry standard is Corflute.
- Common Spec: 5mm thickness (Standard for durability).
- Key Feature: High UV stabilization (to survive the Australian sun).
- Mounting: Often used with “Box Edge” finishes for insertion into metal frames.
- Standard: Must comply with AS 1742.3.

USA & North America: Coroplast Signs (4mm & Wire Stakes)
In North America, the dominant term is Coroplast.
- Common Spec: 4mm thickness (Standard for Yard Signs).
- Key Feature: Cost-efficiency for high-volume printing.
- Mounting: Typically used with Wire Stakes (H-Stakes) or grommets.
- Standard: Often evaluated under MASH guidelines for roadside safety.

UK & Europe: Correx Boards
In the UK and parts of Europe, the trade name is Correx.
- Common Spec: 4mm or 6mm fluted board.
- Usage: Temporary street works and estate agent boards.
Hardware Compatibility: Box Edge vs. Wire Stakes
This is the critical part for procurement officers. You cannot simply swap the terms without checking the hardware.
The “Box Edge” vs. “Wire Stake” Problem
If you order “Coroplast” signs from a US supplier for an Australian road project, you will likely receive 4mm flat sheets.
- The Result: These sheets will fit loosely in Australian metal frames. They may blow out in high winds. They lack the Box Edge rigidity required by local councils.
If you order “Corflute” signs for a US election campaign, you might receive 5mm rigid boards.
- The Result: These boards may be too thick for standard US H-Stakes. You will need expensive custom hardware to install them.
The Lesson: Always specify the mounting system along with the temporary signage material.
Sustainability: Recycling Temporary Signage Materials
Regardless of the name—Corflute, Coroplast, or Correx—corrugated plastic is an eco-friendly choice.
- Recyclable: Polypropylene (PP) is a Code 5 plastic. It is 100% recyclable.
- Non-Toxic: It produces no toxic fumes when processed.
- Durable: It withstands moisture and chemicals better than paper or cardboard alternatives.
