6x3 Timber Treated

What Is 6x3 Timber?

At Materials Market, we only sell the highest quality C24-graded 6x3 timber. But what does C24 mean exactly?

C24 grade is the superior cousin of C16 and offers a stronger, more robust product than lower-graded timbers as it comprises considerably fewer knots. This renders it compatible with structural applications that require durability and sturdiness, such as floor joists or roof battens.

6x3 timber is also highly versatile in the sense that it is suitable for general construction, as well as a range of garden projects. 

C24 timber is particularly ideal for bearing heavier loads and spanning wider areas than lower-graded timbers. This high-quality timber can only be sourced from regions where the climate produces a slower growth rate (and tighter grain).

We stock 6x3 timber in lengths of 3.6m, 4.8m and 6m- these are also available in packs of 49. We also stock a range of accessories (such as wood screws) to help you get your project underway. 

Should you require a different size, we stock a wide range of sizes, lengths and timber related products to accommodate your project needs. 

6x3 Carcassing Timber Applications

6x3 carcassing timber is a kiln-dried treated structural graded softwood that is manufactured to perform in applications where a grading stamp is required. 

It can be applied both internally and externally and is a premium material choice for floor joists, roof joists, and timber framing construction.

6x3 carcassing timber performs best in the following applications: 

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

6x3 Timber Specifications

• Graded to a superior C24 standard - excellent tensile strength
• Regularised with an eased edge - comfortable handling
• High-density
• Finished size: 145 mm x 70 mm ( 6″ x 3″)
• Pressure treated with Tanalith 'E' - helps to prevent rot and protect from moisture 
• Kiln dried for extra stability

6x3 Timber Sizing Explained

6x3 timber is most often measured in inches, which is an imperial measurement, though it is sometimes measured in metric and this is where millimetres (mm) come into play. 

The sizing of 6x3 timber is considered to be either:

• Nominal Size: 75mm x 150mm
• Finished Size: 72mm x 145mm

This slight discrepancy is accounted for by the way the timber is cut and prepared. The difference in the two sizes is minuscule and should not make a meaningful difference to your project. At Materials Market, we sell the finished size (72mm x 145mm). 

Why Choose Treated Timber? 

C24 pressure-treated timber doesn't need your constant supervision to stay in good shape. Its pressure treatment protects it from fungal and insect damage, so you can rest easy knowing that it can sustain itself. 

Here are just a handful of the many benefits on offer with treated timber:  

• It is treated to resist rot, decay and insect attacks
• The most durable timber option which offers extra stability, making it ideal for outdoor use
• Thanks to its treated nature, treated timber is also low-maintenance
• You won't have to spend time and money regularly maintaining it
  
  

What Does Pressure Treated Mean? 

Pressure-treatment is a process in which high pressure forces a preservative deep into the timber's structure. This simple process adds years, sometimes even decades, to the lifespan of natural materials like wood.
