Q-Deck York style decking is made from high quality certified softwood. Its finished size after machining is 33 x 120mm and is a reversible profile. Using the smooth face up gives a more classic contemporary look and actually proves easier to maintain. Being the largest section of decking in the Q-Deck range makes it the strongest board meaning subframe joists can be spaced at centres up to 600mm. On the reverse side all five grooves of York style decking can accept Q-Grip strips, which enables deck builders to incorporate slip resistant areas to their deck, where it is needed. Having a groove that a Q-Grip strip can be placed in at the edge of the board is very useful for slip resistance applications on step or border edges. It is preservative pre-treated with Tanalith.
