47mm x 175mm Sawn Treated Timber C24 (7" x 2") 3m

What Is 7x2 Timber 3m?

47mm x 175mm Sawn Treated Timber C24 (7" x 2") 3m is a high-quality, pressure-treated timber product designed for a wide range of structural applications. Available in C24 grading, this timber is specifically engineered to meet the strength and load-bearing requirements of more demanding construction projects, ensuring reliability and safety across various applications.

Measuring 47mm x 175mm nominally (with a finished size of 45mm x 170mm), this timber is suitable for a diverse range of structural uses, including flooring joists, roofing, timber framing, and other general joinery applications. It is commonly used in both residential and commercial construction where enhanced structural performance is required.

Our 7x2 Timber 3m is kiln-dried and pressure-treated, ensuring superior protection against environmental factors such as moisture, rot, and insect infestation. The Tanalith 'E' treatment significantly enhances the timber's durability, making it ideal for both internal and external uses. 

With its planed all-round finish, 7x2 Timber 3m provides a smooth, easy-to-handle surface that facilitates comfortable and efficient installation. 

Longer lengths and other timber sizes are also available online and by enquiry.

Please Note: The finished size of our carcassing timber may vary slightly from the nominal dimensions. You can expect to receive timber that is finished with a thickness 2mm less and a width 5mm less than the nominal measurements stated. Colour and finish are representative only and may vary slightly as this is a natural product.

Where is 7x2 Treated Timber 3m Used? 

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.

Our 7x2 Timber 3m is generally used in the following building applications: 

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

7x2 Treated Timber 3m Benefits

• Pressure treated with Tanalith 'E' to prevent rot and protect from direct contact with moisture
• Kiln dried for extra stability and straightness
• 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.

Timber Sizing Explained

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. Our 7x2 timber offers longer lengths of up to 6m.

Timber sizes are often referred to as either nominal or finished. With a nominal size of 47mmx175mm, this product actually has a finished size of 45mmx170mm, but this difference is so negligible that it is commonly just referred to as 47x175, or 7x2.
