Timber Decking Joists
Using the correct specification decking joists is vital when building a deck, both in terms of the class of treatment the deck joist has received and the strength rating of the components.
Q-Deck deck joists are available in two specifications:
- C16 strength graded (Note: each joist has printing along the entire length of one of its widest faces) treated to use class 3 (for use out of ground contact)
- C24 strength graded treated to use class 4 (for use in ground contact), marketed as multi-purpose.
The multi-purpose joists do not have print on the face of the board, so they are ideal for making other garden structures such as pergolas, benches and even heavy duty decking, as well as normal decking.
All Q-Deck decking joists are preservative pre-treated, with a built-in water repellent, and come with a 15-year product warranty against fungal decay and wood boring insect attack.
