Treated Timber Decking Joists

Go On!... Make your Garden Smile :)

Treated Timber Decking Joists



When building your own deck, ensuring you have the correct sturdy base to build upon is essential. Treated timber decking joists are a popular choice for many DIYers’ thanks to their lifespan of up to 15 years.

Treated timber decking joists are far superior to non-treated timber as they are not only manufactured from high quality timber, they have also been pressure treated too to give them a longer lifespan.

Pressure treating timber also creates a barrier against rot and fungi. Whilst treated timber can be a little more expensive to invest in at first, unlike standard timber joists, they will last far longer, so you won’t have to spend money replacing them every few years – making them a very cost-effective investment.

Finding joists for an exceptionally large DIY project or for an exceptionally small one is a breeze at eDecks; if you can’t find the size you’re looking for amongst our pre-cut range, we’ll cut your timber joists to size.
