Timber  Decking Species

We can source any timber, apply our non-slip inserts  and supply it as GripDeck® Decking. Most GripDeck® Hardwood Decking timbers are manufactured to order however we do keep limited supplies of GripDeck® Hardwood Balau Decking. Choose from a selection of timbers below or get in touch if you can’t see what you need.

Further info on different types of hardwood can be found on the TRADA website

*Hardness – Monnin hardness is measured by pressing a cylinder with 30mm diameter into the wood perpendicular to the grain with a force of 200daN for 5 seconds. (1daN == 10N, 200daN == 203.94 kilogram-meters.) The depth t of the depression left by the cylinder is measured in millimeters, and the Monnin hardness N is then calculated as 1/t.

**Stability – If sudden shifts of moisture level or temperature are common, then cracking or splitting may become an issue. Warping can be kept at bay with correct installation and frequent oiling.
