6.0Mtr X 47 X 200mm C24 Treated Regularised KD Carcassing Timber
Selecting the right size
This 47 × 200mm section is commonly used for floor joists, roof battens, stud walls, and decking frames. The 6.0 metre length suits standard building spans and reduces waste on many projects. Consider your specific load requirements and span distances when choosing between available sizes; C24 timber offers superior load-bearing capacity compared to C16 grade.
- Check your building design or structural engineer's specifications for required timber grade and dimensions
- Verify that the 6.0 metre length suits your project layout to minimise cutting and waste
- Confirm moisture content is kiln-dried (KD) to reduce movement and twisting after installation
Understanding the treatment
This timber is pressure-treated with preservative to protect against rot, fungal decay, and insect infestation. The treatment is integral to the timber's durability, particularly in damp or external environments. Treated timber requires careful handling during installation to maintain the integrity of the protective coating.
- The preservative treatment provides long-term protection in both indoor and outdoor applications
- Avoid unnecessary cutting or damage to the surface that could expose untreated wood
- Where cuts are made, consider applying additional preservative treatment to exposed surfaces in external applications
Storage and handling
Proper storage protects the timber's quality and treatment before installation. Keep the timber dry and well-ventilated to maintain its kiln-dried moisture content and prevent warping or twisting.
- Store on level ground with adequate air circulation underneath
- Keep the timber covered to protect from rain and direct sunlight
- Handle carefully to avoid damage to the planed finish and treated surface
Fixing methods
C24 Treated Carcassing Timber is typically fixed using standard fastening methods appropriate to your application. The smooth, planed finish makes it straightforward to work with using conventional tools and fixings.
- Use appropriate fasteners (nails, screws, or bolts) sized for the timber section and load requirements
- Follow your structural design or building regulations for fixing spacing and methods
- Ensure fixings are corrosion-resistant when used with treated timber in external applications
