3.6m x 150mm x 22mm Wooden Gravel Board – Pressure Treated Green

Pressure-Treated Protection for Closeboard Systems

This 3.6m x 150mm x 22mm green wooden gravel board is UC4 pressure treated for durability and ideal for ground contact. It forms the base of any quality closeboard fencing system, helping to raise feather edge boards away from moisture at ground level, reduce rot, and increase overall fence lifespan.

Often paired with a 1.65m feather edge board to create a finished fence height of approximately 1.80m (1.65m + 0.15m), this board is suitable for both domestic and commercial fencing projects. The most popular finish height is 1.8m or 6ft.
