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).
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

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.
Frequently Asked 6x3 Questions
Is It Possible To Paint 6x3 Timber C24?
Pressure-treated wood can be painted or stained, but to get a finish that lasts and looks premium, you'll first need to evaluate the moisture content of the timber.
Once you are sure the timber is dry, you can then move on to using a suitable primer and paint finish. We recommend using a latex primer with compatible exterior latex paint—water-based paint. Oil-based paints are not recommended.
Am I Able To Cut Treated Timber To My Preferred Size?
Yes, it is possible to cut treated timber, provided that you have all the appropriate power tools, eye protection, and a respirator to hand before cracking on. Donning the correct PPE is essential as the cutting process releases tiny airborne particles of wood, possibly impregnated with the chemicals used in pressure-treating.
Treated wood also cuts a little more like wet wood so some extra care should be afforded to ensure the blade doesn’t slip while cutting.
Is 6x3 Treated Timber Environmentally Sustainable?
All of the treated timber for purchase on the Materials Market website is Forest Stewardship Council (FSC) or Programme for the Endorsement of Forest Certification (PEFC) certified, which means that the timber we stock is in good condition and responsibly sourced from environmentally responsible suppliers.
