Correx® Signs 6mm

6mm Correx® Board

6mm Correx® signs are lightweight, tough, fluted polypropylene boards for short to medium-term indoor/outdoor advertising. Weather resistant, it can be easily set up with nails, screw, glue or drill holes. The board is popular for temporary needs such as event directions, estate agent boards and site safety signs. Its twin-wall fluted structure is impact resistant yet easy to handle, cut, drill and install with cable ties, screws or frames.  Colourful and fully customisable 6mm Correx® is a practical choice where strength, durability and value for money are required.

The 6mm option is an alternative to the standard 4mm Correx® sign board and offers better overall strength and additional protection from wind and other weather conditions when used for large-format signage. Finished on-site using HD UV flatbed print technology, this board is a perfect medium for constructing construction hoardings, as well as a budget-friendly option for large-scale events and permanent outdoor advertisements.

The Power of 6mm Sheet: Why Upgrade?

Most people are familiar with the standard 4mm board for estate agent signs. But why buy 6mm Correx® sheets? That depends on the structure.

1. Superior Rigidity & Flatness: Thinner fluted boards are prone to “bow” or warp when printed in large sheets (A0 or 8ft x 4ft). The 6mm Correx® board has thicker internal flutes and tougher outer skins. 
2. Increased Impact Resistance: Signs get battered on active construction sites or busy festival grounds. They are knocked over by equipment, footballs, or scraped by passersby. The addition of 2 mm of thickness creates a cushion. 
3. Better Wind Resistance: If you are mounting signage on a post or wire fence in an exposed area, wind load is a consideration. The structural integrity of 6mm Correx® sheets makes them very resistant to wind pressure and reduces the risk of the sign folding or tearing away from its fixings. 

Practical Applications: When to Use 6mm Correx®

We recommend upgrading to 6mm Correx® signs for the following specific use cases:

• Construction Hoarding & Site Perimeter: When cladding a site perimeter, you need a material that covers large gaps and withstands months of outdoor exposure. 6mm Correx® board is the cost-effective alternative to Aluminium Composite (DiBond) for temporary hoardings. 
• Large Commercial Estate Agent Boards: Using 6mm Correx® ensures your large commercial agency boards remain rigid and readable, projecting an image of high-value professionalism.
• Outdoor Event Wayfinding: For music festivals, marathons, or outdoor markets (e.g., a site map or stage lineup), 6mm Correx® sheets prevent the “floppy” look associated with cheaper materials, ensuring your event looks premium.
• Temporary Shop Fronts: If you are refitting a shop and need to cover the windows or the fascia temporarily, 6mm Correx® provides a secure, opaque visual barrier.

Custom Shapes and CNC Finishing

Just because it is thicker doesn’t mean it can’t be customised. Our Perivale production floor is equipped with industrial cutting tables capable of slicing through 6mm Correx® board with surgical precision.

• Contour Cutting: We can cut your heavy-duty board into arrows, circles, or the shape of your product.
• Drilled Holes: We can pre-drill holes in the corners or along the edges to match your specific fence fixing points, saving you installation time.
• Creasing: While harder to fold than 4mm, 6mm Correx® can still be creased for specific structural packaging or display applications. 

Although thicker than other options, 6mm material may be shaped and finished in order to provide custom Correx® signs for project needs, for both flexibility (rigid) as well as unique or non-standard sign configurations.
