What are 3m Decking Boards?

3m decking boards are long, pre-cut outdoor flooring planks—typically made from composite or timber, that span 3 metres in length. They are designed to create smooth, even surfaces for patios, terraces, gardens, or balconies. Their extended length reduces the number of joints required, delivering a cleaner aesthetic and simplifying installation.

Selecting the Right Decking Board

When choosing a decking board, consider factors like durability, maintenance, aesthetics, and the specific environment where the deck will be installed. Composite boards are generally more durable and require less maintenance than traditional wood boards. Consider the board's resistance to weather, fading, and staining. Additionally, the choice between hollow and solid boards depends on your specific structural and aesthetic needs.

Installation Tips

  • Joist Spacing: Maintain correct joist spacing (typically 300mm–400mm) to support the 3m board length.
  • Expansion Gaps: Leave a 5mm–8mm gap between boards to allow for thermal expansion.
  • Use Hidden Fasteners: For a sleek look, use clip systems or hidden screw fixings recommended by the manufacturer.
  • Solid Subframe: Ensure your decking base is strong, level, and built with treated timber or composite joists.
  • Cutting Boards: Use fine-toothed circular saws or mitre saws for clean edges when cutting composite boards.
