Composite decking requires a solid and good quality subfloor that will make sure your deck has the longest possible usage time. In Australia, there is a National timber structure standard AS1684.4-2000. Building a deck subfloor following this standard will guarantee that your deck frame is solid and compliant with regulations. At WoodEvo, we are not only selling deck boards, but we are also helping our customer’s tradies to build the best deck.
