47mm x 150mm Sawn Treated Timber C24 (6" x 2") 4.2m

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

It's no secret that the UK is known for its grey skies and rainy weather; in fact it's part of its charm. Much like moisture and insect attack protection is part of 4.2m 6x2 treated timber's charm. All of our sawn timber is treated and kiln dried, ensuring maximum protection against insects and dreary UK weather. 

These 6x2 timber 4.2m lengths have been planed all around to produce a smooth easi edge that makes them comfortable to handle.

They have a C24 grading, which makes them suitable for structural applications such as flooring, roofing, as well as timber framing and other general joinery applications. All of our timber is FSC or PEFC certified, which means it has been responsibly sourced from sustainable forests.

47mm x 150mm Sawn Treated Timber C24 (6" x 2") 4.2m Applications

6 x 2 treated timber, often called 150x50 carcassing timber, is a mainstay of the building trade.

C24 timber is the superior cousin of C16. Offering superior strength and durability, 47x150 treated timber is especially suited to carcassing, often being utilised as joists in roofing or flooring. 

C24 timber is fine to use in external applications as long as it has been treated. Treated wood can endure the elements and is therefore ideal for decking, external buildings, and other applications.

Some other examples of how 6 x 2 timber lengths can be used are: 

• Flooring
• Stud walls
• Roofing - rafters/joists in a loft floor
• Walling
• Decking joists - as it is able to bear heavier loads than ungraded timber (or that which is graded to a lower level such as C16.)
• Carcassing timber in floor joists
• Garden furniture and other outdoor projects

What is C24 Timber? 

The term "C24 grade" is used to describe a higher timber quality than that of C16. C24 timber is a premium choice that can support higher loads and wider spans.

Only timber imported from areas where the weather conditions demand a slower growth rate (and hence a tighter grain) achieves a C24 grade

6x2 Timber Sizing Explained

With a nominal size of 47mmx150mm, 6x2 timber actually has a finished size of 45mmx145mm, but this difference is so negligible that it is commonly just referred to as 47x150, or 6 x 2. 

Here at Materials Market, we sell a huge range of treated timber in a variety of sizes and lengths. Our high-quality C24 grade treated timber comes in 2.4m, 3m, 3.6m, 4.2m, 4.8m, 6m and 7.2m, with a consistent thickness of 47mm.
