3x2 Timber

3x2 timber is most commonly used for framing, particularly in residential construction for wall studs and roof rafters where its relatively smaller size is suitable. It's also commonly employed in DIY projects such as garden structures due to its manageable dimensions and structural strength.

We offer a range of 3x2 timber - all suitable for structural applications, both treated and untreated. As well as standard 3x2 timber, we also offer 3x2 CLS timber, which although they are named similarly, has slightly smaller dimensions and is ideal for stud walls and partitioning. 

Timber sizing can be confusing if you are not already familiar with it, but once you understand it is quite simple. “3x2” refers to the traditional way of measuring timber - in inches. In millimetres, this roughly translates to 47x75mm. However, as our structural timber is regularised - a process where each side of a length of timber is planed to achieve a uniform finish - in reality the dimensions are typically a few mm smaller than that - more like 45mm x 70mm. The exception is CLS timber, which is planed on all sides, making it’s dimensions a further few mm smaller - approx 38mmx63mm.

Our treated 3x2 timber is treated to UC2 and can be used in outdoor construction, though timber in direct contact with moisture may need further treatment. Our CLS and untreated 3x2 timber is more typically used indoors in the construction of timber frame structures, although treated timber can also be used, as it simply gives it additional resistance to moisture and pests.

3x2 timber (75mm x 50mm) represents one of the most versatile dimensions in construction, offering the perfect balance of strength and workability for countless applications. From garden structures to internal framing, this dimension provides excellent load-bearing capabilities whilst remaining manageable for both DIY enthusiasts and trade professionals.

Our carefully selected 3x2 timber range features premium grades sourced from trusted British suppliers, ensuring every length meets the demanding standards of UK construction. Each piece undergoes rigorous quality control, giving you timber that's straight, strong, and ready for immediate use.

Internal Studwork and Partitioning When creating internal walls or partitions, 3x2 timber provides the structural integrity needed for plasterboard fixing whilst maintaining manageable weight. The 75mm face offers excellent fixing capacity, whilst the 50mm depth keeps wall thickness to a minimum - crucial in modern construction where space is at a premium.

Garden Frameworks and Outbuildings For shed construction, pergolas, and garden frameworks, 3x2 timber delivers the strength to withstand British weather conditions. The dimension works perfectly for creating robust frameworks that support cladding, roofing, and other structural elements.

Roofing Applications As rafters in smaller structures or purlins in larger roofing projects, 3x2 timber provides reliable performance. Its manageable size makes installation straightforward whilst delivering the structural capacity essential for safe, long-lasting roofing systems.

Premium Grades for Professional Results

Our 3x2 timber selection includes C24 grade timber - the premium structural grade that exceeds standard C16 specifications. With higher strength values and reduced defects, C24 timber ensures your projects meet Building Regulations requirements whilst providing superior performance and longevity.

For treated applications, we stock pressure-treated 3x2 timber that provides enhanced protection against moisture and insect damage. This treatment process forces preservatives deep into the timber structure, creating lasting protection that surface treatments simply cannot match.

Expert Selection Guidance

Choosing the correct 3x2 timber specification depends on your specific application requirements. For internal use, our kiln-dried options provide excellent dimensional stability and reduced moisture content, minimising shrinkage and movement after installation. For external applications, our pressure-treated range offers the weather resistance essential for long-term performance.

Length availability extends from 2.4m to 4.8m, allowing you to select optimal lengths that minimise waste whilst meeting your project requirements. Our team can advise on the most cost-effective lengths for your specific application.

Quality Assurance You Can Trust

Every piece of 3x2 timber in our collection meets British Standards BS EN 14081, ensuring consistent quality and performance. Our suppliers maintain full chain of custody certification, guaranteeing responsible sourcing from sustainably managed forests.

We understand that timber quality directly impacts project success, which is why we maintain rigorous inspection standards. Each delivery is checked for straightness, moisture content, and grade compliance before leaving our facility.

Professional Support When You Need It

Our experienced team understands that selecting the right timber specification can be challenging. We're here to provide expert guidance on grades, treatments, and lengths to ensure your project succeeds first time. Whether you need advice on spanning tables, fixing requirements, or treatment options, our knowledge is at your disposal.
