  • Treated and garden-ready - Our garden decking boards are pressure treated to withstand harsh weather, resist rot and decay, and prevent moisture damage. These treated timber boards are designed to last.

  • Dual Sided - The wooden decking boards have a grooved edge that can reduce the chances of slipping when the boards are wet. They also have a smooth face to them if you prefer a cleaner look.
  • Versatile - These boards aren't just for decking, patios, and raised areas. They can be used in a variety of DIY projects, including fencing, railing, outdoor shelving, and many more outdoor structures.
