75 x 47 (3″ x 2″) Timber Joist Brown Treated

Our 75mm x 47mm (approx. 3″ x 2″) Treated Timber Joists are engineered for structural integrity in outdoor environments. These joists provide the reliable load-bearing performance required for decking subframes, garden buildings, and pergolas. Available in 2.4m, 3.0m, and 3.6m lengths. To ensure a long service life, each length is Pressure Treated (Tanalised) with a deep brown preservative. This treatment forces protective chemicals deep into the wood fibres, providing a robust barrier against fungal attack, wood-boring insects, and wet rot. The regularised finish means the timber has been planed to consistent dimensions with slightly rounded edges, making it easier to handle and ensuring a level, professional frame for your project. Pressure Treated (Brown): High-pressure preservative treatment ensures longevity and protection against the elements, with a pre-coloured brown finish to match traditional garden aesthetics. Kiln-Dried & Regularised: Precision-finished to consistent 75mm x 47mm dimensions, ensuring your framework is uniform and easy to build upon. Versatile Outdoor Use: The ideal size for creating sturdy decking joists, roof rafters for sheds, or heavy-duty fence framing. Eased Edges: Rounded corners for safer handling on-site and a cleaner finished look. Structural Support: Designed to provide a solid and durable skeleton for various outdoor construction projects.
