3x2 Treated Timber C16 Kiln Dried Regularised Joist 47x75mm – 2.4m

The term "3x2," indicates the joist size in inches and corresponds to 47 x 75mm in metric measurements. However, regularised timber is mechanically finished to achieve a smooth and uniform size across the length of timber, resulting in a "finished" size slightly smaller, approximately 45mm x 70mm.

The size difference is negligible and in the vast majority of projects will make no difference to your project, and is standard across 47x75, 3x2 regularised timber joists.

C16 CLS Studwork Timber is commonly employed in constructing timber-framed homes, including applications such as stud walling, carcassing, interior framing, and partitioning. Its C16 grade ensures exceptional strength, making it well-suited for various interior construction uses.

Kiln-dried refers to a process where timber or wood is placed inside a kiln to remove excess moisture from it. The controlled heat and airflow in the kiln facilitate faster and more uniform drying compared to air-drying methods. This process reduces the moisture content of the wood, making it lighter, stronger, less prone to warping or cracking, and more stable for various applications in construction, woodworking, or furniture making.

We offer 3x2 timber in lengths of 2.4m, 3m, 3.6m, and 4.8m. We strive to maintain stock across all sizes for delivery, but occasionally there are instances of delay or unavailability of specific sizes, where we may substitute longer lengths in the interest of getting your order to you in a timely manner.

In the UK, timber is often graded based on strength and quality, with C16 and C24 being two common classifications for coniferous wood, like pine or spruce. These grades indicate the timber's load-bearing capacity, especially under bending stress.

C16 and C24 are primarily used in construction for structural purposes. C24, being the stronger grade, is often chosen for applications requiring higher load-bearing capabilities, such as in larger spans or heavier loads. It's more resistant to bending and suitable for more demanding construction projects.

On the other hand, C16 timber, while slightly lower in strength compared to C24, is still robust and finds extensive use in various wall and roofing applications where the load requirements are less stringent. Both grades offer reliable performance, but the choice between them depends on the specific structural demands of the project and cost considerations.

Our 3x2 Treated Timber is suitable for both internal and external uses. If your project might face moisture or pest challenges, opting for treated timber could be more suitable. Treated timber is better suited for outdoor projects such as decking, roofing, and similar applications due to its enhanced resistance to moisture and pests.
