Q: Are JT Atkinson's timber deck boards treated?

A: Yes,  all of our decking timber boards are pressure-treated to help protect against rot, fungal decay and insect attack. That makes them a great low-maintenance option for outdoor use. Our decking oils and wood treatments can help protect your wooden decking boards further.

A: We do. We stock both non-slip timber decking boards and grooved options to help reduce the risk of slipping, which is ideal for areas exposed to rain or frost, or where extra grip is needed underfoot.

For example, the Arbordeck Premium Smooth and Grooved Tanalised boards  provide a grooved, slip-resistant surface, helping you maintain a good grip when walking on them.
