47mm x 250mm Sawn Treated Timber C24 (10" x 2") 4.8m

Colour and finish are representative only and may vary slightly as this is a natural product.

Invest in quality with 4.8m 10x2 C24 Treated Timber. Here at Materials Market, all of our sawn timber is pressure treated and kiln dried, giving additional protection against bugs and moisture. 

These 10x2 timber 4.8m lengths have been planed all round to produce a smooth easi edge that allows for comfortable handling. 

Despite a nominal size of 47mm x 250mm, their actual finished size is 45mm x 245mm. As carcassing timber they have a C24 grading, which makes them suitable for structural applications such as flooring joists, roofing, as well as timber frame stud walls and other general joinery applications. 

What's more, all of our timber carries FSC or PEFC certification, which means it has been responsibly sourced from environmentally sustainable suppliers. Longer lengths and other timber sizes are also available online and by enquiry.

10x2 Treated Timber 4.8 m Applications 

Carcassing timber is a kiln-dried treated structural graded softwood that is most often seen in construction where a grading stamp is needed. It can be utilised in a variety of ways both internally and externally, and it's widely used in floor joists, roof joists, and timber framing construction.

No matter the application, it's relatively easy to cut treated timber to the size that you need in your project, though this should only be attempted with the appropriate power tools, eye protection and a respirator.

Carcassing timber is generally used in the following building applications: 

• Stud walls
• Joists for roofs, floors and decking
• Structural and general joinery applications
• Timber framing construction

10x2 Treated Timber 4.8 m Specifications 

Pressure-treated timber, otherwise known as tanalised timber (due to the Tanalith E wood preservative that impregnates the wood) provides many benefits, such as resistance to moisture, meaning weather (even UK weather, unbelievably) will not affect its structural integrity.

Let's check the specifications: 

• Graded to a superior C24 standard - excellent tensile strength
• Regularised with an eased edge
• Pressure treated with Tanalith 'E' to prevent rot and protect from direct contact with moisture
• Kiln dried for extra stability and straightness
• FSC Certified - responsibly sourced
• High-density
• Cost-effective - competitive price with quality guarantee

What Does C24 Carcassing Timber Mean?

C24 grade is superior to C16, offering greater strength with more knots than lower graded timbers. This suits it to tasks which require durability and sturdiness, namely structural applications, such as floor joists or roof battens.

C24 timber is a premium choice that can support higher loads and wider spans. Only good quality timber imported from areas where the weather conditions demand a slower growth rate (and hence a tighter grain) achieves a C24 grade.

Here at Materials Market, all of the timber we sell is treated with preservatives, kiln dried, and then planed on all four sides to give it an easi edge profile that makes for easy handling.
