4x2 Timber Treated C24 (6 Products)
When it comes to timber, fungal and insect attacks are no joke. Insects can bore into timber, causing it to become structurally unsound; the damage of which is not only costly to repair but also a serious safety hazard. 4x2 treated timber is a quality C24 graded timber that has been pressure-treated to prevent both fungal and insect attack. We supply good quality 50x100 timber in various lengths: 2.4m, 3m, 3.6m, 4.2m, 4.8m and 6m.Find Out More About Our Types of 4x2

4x2 Timber Treated C24
What is 4x2 C24 Wood Used For?
There are a huge number of different uses for 4x2 timber as it is an extremely adaptable structural building material. Thanks to the protective treatment of the timber, and its C24 grading, 47x100 treated timber can be used in many different indoor and outdoor applications such as:
- Roofing - rafters/joists in a loft floor
- 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's The Difference Between Treated Timber & 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, 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.
What Size Is 4x2 Timber In mm?
4x2 timber is most commonly referred to in inches (4x2). In metric, however, it is specified as 47mm x 100mm or 50mm x 100mm. This discrepancy is accounted for by the way the wood is cut and prepared. As the 47mm and 50mm are largely interchangeable (due to the minuscule difference between them) either size falls under 4x2.
Frequently Asked 4x2 Questions
Can I Paint 4x2 Treated Timber?
Absolutely! Painting treated timber wood will not only help you achieve your ideal aesthetic but also gives the wood an additional layer of protection, which is something you want. When painting pressure-treated wood, however, you must be careful.
Most 100mmx50mm timber is still “wet” and needs time for the chemicals permeating the wood to settle and dry. At this point, the wood is noticeably heavy and will still feel damp to the touch. If primer or paint is added to it at this point, there is every likelihood that it will be rejected by the water-based chemicals that are still working their way through the wood.
It is important to permit the timber to dry out fully before attempting to add paint or primer. This can be a lengthy process and may even take up to a few weeks depending on where the wood is stored. If there is too much heat and direct sunlight, this can cause the treated timber to warp instead of dry out. Damp conditions can also prolong the drying-out period.
How Can I Tell if Wood is Treated?
There are a few indicators that timber has been pressure treated. The first is that it should be labelled as such with a stamp. However, when timber is cut to size, this occasionally gets removed.
Another tell is the colour of the timber; treated wood that is still relatively new should have a green tinge to it. This green hue fades over time and becomes honey gold before turning silver.
The smell can also be an indication, but this is only really effective when the wood is relatively fresh. New pressure-treated wood will carry a slight chemical smell, whereas non-treated wood won't. Again, this isn't a foolproof method and only works on freshly treated timber.
Treated Timber Benefits
There are a plethora of timber types on the market from treated, untreated and sawn carcassing timber. It is essential to use good quality treated timber for your construction projects as timber is usually located in places that are not easy to get to. This means we usually have no way of knowing if parts of the structure are under attack from insects or dampness, thereby weakening it.
C24 graded timber has been pressure-treated to counteract both fungal and insect attack.
Let's get into treated timber's many other benefits:
- It is treated to resist rot, decay and insect attacks
- The most durable timber option, 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
Is 47x100 Treated Timber Environmentally Sustainable?
All of the timber lengths sold by Materials Market are Forest Stewardship Council (FSC) or Programme for the Endorsement of Forest Certification (PEFC) certified, which is a certification to show that the timber has been responsibly sourced.
