47 x 100mm Decking Timber Joists

Our treated timber decking joists are pressure treated which is essential when the timber is in contact with the ground to ensure the maximum lifespan possible.

We advise when building your decking frame to keep the spacings between joists no larger than 450mm to avoid your decking bouncing when being walked on.

Don't forget to include some extra lengths for noggings between the joists. Based on the joists being 450mm apart we would recommend fixing a nogging every 1500mm.
