The 22mm x 150mm x 3m treated timber—commonly known as 6x1—is a pressure-treated board that offers strength and long-lasting protection against moisture, decay, and insects. It’s ideal for exterior applications such as fencing, cladding, garden borders, or general-purpose landscaping and construction. The 3-metre length provides extended coverage, reducing the number of joints required while still being manageable to work with. Easy to cut, fix, and finish, it’s a dependable solution for outdoor projects that need a robust, weather-resistant material.
