8x2 Timber Treated C24
(14 Products)
For strength, durability and stability, look no further than high-quality C24 graded 8x2 treated timber. Often referred to as 200x50 timber, 8x2 timber is one of the mainstays of the building trade. All of our 8x2 timber is sawn to length and pressure treated with chemicals to prevent fungal or insect attack. Here at Materials Market, we offer a good selection of 8x2 C24 timber lengths: 3m, 3.6m, 4.2m, 4.8m, 5.4m, 6m and 7.2m.

What is 8x2 Carcassing Timber Used For?
8x2 carcassing timber is a kiln-dried treated structural graded softwood that is most often seen in construction where a grading stamp is needed.
C24 grade is superior to C16, offering greater strength with fewer knots than lower graded timbers. This suits it to tasks which require durability and sturdiness, namely structural applications,
It can be utilised in a variety of ways both internally and externally, and it's widely used in floor joists, roof joists/roof battens and timber framing construction.
Carcassing timber can be used in the following building applications:
- Stud walls
- Joists for roofs, floors and decking
- Structural and general joinery applications
- Timber framing construction
8x2 Timber Benefits
- It is treated to resist rot, decay and insect attacks
- C24 timber can support higher loads and wider spans
- Good quality timber imported from areas where the weather conditions demand a slower growth rate (and hence a tighter grain)
- 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
8x2 Timber Sizing Explained
8x2 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 8x2 timber is considered to be either:
- Nominal Size: 47mm x 200mm
- Finished Size: 45mm x 195mm
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 (45mm x 195mm).
Frequently Asked 8x2 Questions
Is It Possible To Paint 8x2 Timber C24?
It's actually very easy to paint treated wood, but it's important to keep in mind that the wood should be allowed to completely dry out before any paint or primer is applied.
Be mindful of where you store the timber post its delivery, as too much heat or direct sunlight can cause the timber to warp rather than dry out. Conversely, damp conditions can lengthen the drying out period, prolonging the time before work can begin.
Am I Able To Cut Treated Timber To My Preferred Size?
Absolutely, to cut treated timber to size is a simple task, however, be sure to have all the appropriate power tools, eye protection, and a respirator to hand before cracking on, since 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 8x2 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.
What Is The Difference Between 8x2 Treated Timber and 8x2 Sawn Timber?
Sawn timber is wood that has been cut to the required dimensions but hasn't yet been pressure treated and kiln dried. 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 the elements.
The goal of pressure treating wood is to force preservative chemicals deep into the timber's cellular structure. This pressure treatment process will often include copper and organic co-biocides, which help to repel both insects and moisture.
Please note: timber is a natural product that may vary in colour, visual details, knots, grain, and texture.
