Slip Resistant Composite Decking

Slip Resistant decking you can enjoy with confidence

A big concern with a lot of outdoor decking is that in the wrong weather, it can end up being too unsafe to enjoy. And it isn’t just wet weather that poses a hazard: timber-based decking is prone to algae and fungal growths that can make the surface even more slippery. Even conventional composite decking can suffer from these problems, due to its timber content. In contrast, Millboard decking is made from an entirely wood-free material – it provides genuinely anti-slip decking.

Keep the look – lose the hazard

Each of our decking boards is formed from a unique resin/mineral composite, with no wood content at all. As a result, there is nothing to encourage algal or fungal growth, and our unique Lastane ® coating has tremendous anti-slip performance. But while Millboard decking avoids the problems associated with wood, it manages to retain all wood’s beauty. Moulded from carefully selected oak samples and coloured by hand, its grain and colouring make it virtually indistinguishable from real timber.

Independently tested

 When it comes to safety regulations, Millboard’s anti-slip decking passes independent tests, easily surpassing the British Standard Institute’s and Health and Safety Executive’s guidelines. In the wet especially, it significantly out-performs any wood or wood composite decking. Our Weathered Oak range has a wet slip resistance of rating of 54 and our Enhanced Grain is 51, both far above the required 36 to pass the requirement for low slip flooring. This figure increases when referring to slopes which goes up to 45 PTV (Pendulum Test Value) for a 5 degree slope, although most slopes are 3-4 degress, nonetheless Millboard still far exceeds the requirement which many composite decking manufacturers fail to meet.

The ultimate in slip resistant decking

While all of Millboard’s decking has excellent anti-slip performance, for areas where safety is paramount we offer Lasta-Grip®. This retains the same authentic wood look of all our products, but has a textured surface to offer the ultimate in slip-resistance, without the rough feel of conventional gritted strip boards.

A complete, high-performance decking system

Millboard’s decking is backed up by accessories that match its performance. Our Plas-Pro sub frame system and adjustable levelling supports are simple to work with, while various edging options, all incorporating the same natural wood-grain, ensure your deck has the perfect finish. Or if you’d rather leave your deck’s construction to experts, we have a network of approved installers to call on.
