Deck Boards

Deck boards form the foundation of any outdoor timber structure, providing the walking surface that must balance durability, aesthetics, and safety. Whether you're constructing a new garden entertaining area or replacing worn sections on an existing structure, selecting the right boards ensures your outdoor space remains functional and attractive for years to come.

Our Deck Boards Collection

We stock a comprehensive selection of boarding options to suit different project requirements and budgets:

"

  • Pressure-treated softwood deck boards (150x35mm x 4.8m, reversible) offering rot resistance and excellent value for residential garden installations.
  • Baltic Redwood treated boards providing a premium timber option with a natural grain finish and extended service life.
  • Gripsure anti-slip boards (150x35mm) in 4.2m, 4.5m and 4.8m lengths, with factory-fitted rubber inserts and a 15-year non-slip warranty.
  • Composite deck boards offering low-maintenance alternatives in multiple colour options.
  • Reversible profiles providing two distinct surface finishes from a single board, maximising flexibility for different project aesthetics.

"

For premium low-maintenance alternatives, explore our Millboard and Whiteriver Composite Decking ranges, which replicate natural timber without the ongoing upkeep requirements.

Consider the board's intended location and expected foot traffic when making your selection. Shaded or north-facing areas benefit from grooved profiles for enhanced grip, while sun-drenched spots may suit smooth finishes. Check joist spacing requirements: thicker boards allow wider centres, potentially reducing subframe material costs on larger projects.
