The 22mm x 150mm x 3.6m treated timber is a durable and versatile exterior-grade board, ideal for a wide range of landscaping and construction projects. Its pressure treatment protects it against rot, fungal decay, and insect damage—making it well-suited for outdoor use in fencing, cladding, raised beds, and general garden or structural framing. The 150mm width offers substantial face coverage, while the 3.6-metre length helps reduce the number of joints needed, giving projects a neater and more robust finish. Easy to handle and cut, it’s a reliable choice for weather-resistant builds.
