7×2 Treated Timber C24 Regularised Sawn 47x175mm – 3.0m

Product Details

Our C24 Timber Joists, measuring 7x2, are made from timber sourced from FSC Certified forests. These joists for floors and roofs undergo kiln-drying to guarantee superior straightness and long-lasting durability. Featuring eased edges, they are 3m in length and sized at 47x175mm (with a finished size of about 45x170mm). Kiln Dried for additional strength and durability FSC Certified For use in timber framing, decking and roofing Regularised for uniform size, with eased corners Graded to C24 strength grade Conforms to BS 4978 and EN 14081:2006 What is 7x2 Timber in mm? In metric measurements, the dimensions of 7x2 timber translate to 47x150mm. However, the actual millimetre size of 7x2 timber is slightly reduced due to the regularisation process our structural timber undergoes. This process involves machining the length of the timber to ensure smooth and consistent dimensions throughout. Consequently, the "finished" size may be slightly smaller than 47x175mm, usually closer to 45mm x 170mm. This slight difference does not impact the large majority of projects and is a standard feature of using 7x2 regularised timber joists. What are 7x2 Treated Timber Joists Used For? 7x2 timber joists can be used in various construction projects, particularly floor joists or in structural projects where the timber is graded to C16 or C24 strength grading. Treated timber is suitable for both internal and external projects. What is Regularised Timber? Regularised timber refers to timber that has been machined to achieve consistent and standardised dimensions. This typically means that the “finished” size is a few millimetres smaller than the stated size. Regularised timber is commonly used in construction because its standardised size makes it easier to work with and ensures consistency in building projects. It's often used for structural components like joists, studs, and rafters, where precise dimensions and a smooth finish are essential for stability and ease of assembly. What Does Kiln Dried Mean? Kiln-dried timber is wood that has undergone a controlled drying process in a kiln to reduce the moisture content. This method enhances the wood's stability, strength, and durability by lowering moisture levels, minimising the risk of warping or cracking, making it ideal for construction. Additionally, the drying process helps deter mould growth and makes the wood less appealing to pests, ensuring its quality and longevity in different applications. What Lengths Do 7x2 C24 Treated Timber Joists Come in? Our 7x2 Timber joists are available in 2.4m, 3m, 3.6m, 4.2m and 4.8m. We try to keep all of these lengths in stock wherever possible, but on occasions where stock levels or availability in your area is low, we may substitute for a longer length. What Is C24 Timber? C24 timber is one of several grades commonly used in the UK. Distinguished by its greater strength compared to C16 timber, the "C" denotes the wood type (coniferous), while the numeral indicates its bend strength rating. Renowned for its exceptional strength and capacity to bear heavy loads, C24 timber is often used in structural roles, requiring timber of superior strength - especially in scenarios involving larger spans, heavy loads, or where bolstered structural resilience is crucial. Do I Need Treated 7x2 Timber? 7x2 treated timber is a versatile choice for various projects, especially when durability and resistance to moisture or pests are required. Its treatment makes it suitable for both indoor and outdoor applications, such as framing, decking, fencing, and even structural support in areas where exposure to moisture or potential pest infestation is a concern. Its adaptability and strength make it a reliable option for a wide range of construction or woodworking projects.
