Shop pressure-treated timber decking boards for garden seating areas, outdoor dining spaces and replacement decking projects. Our range includes two board sections in 3.6m and 4.8m lengths, allowing you to choose dimensions that suit your layout.
Timber decking provides a natural surface that works alongside planted borders, wooden fencing and other garden features. Planning the board direction and joint positions before installation helps create a consistent finish and reduce unnecessary cuts.
| Board section | Available lengths |
|---|---|
| 120 × 28mm | 3.6m and 4.8m |
| 145 × 34mm | 3.6m and 4.8m |

Install decking on a suitable deck frame using compatible exterior fixings. Allow the specified gaps for drainage and timber movement, and treat cut ends with a suitable end-grain preservative.
For decks requiring a railing, browse our decking handrails and matching balustrade components.
Calculate the number of rows using the board width plus the recommended gap. Then consider the length of each run, joint positions and cutting allowance.
Different thicknesses create different finished levels on the same frame. For a consistent surface, use matching boards or a properly designed arrangement that accommodates the difference.
Yes. Gaps allow drainage and accommodate movement. Follow the installation guidance for the chosen boards, taking their moisture condition into account.
Use an appropriate end-grain preservative on cut treated timber, following the product instructions.
