Fixing and buying guide
3.0Mtr X 47 X 200mm (8" x 2") 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 3.0 metre length suits standard joist spacing and wall heights. Consider your span requirements and load conditions when choosing between available sizes—larger sections provide greater load-bearing capacity for longer spans.
- 47 × 200mm is suitable for residential floor joists and stud wall construction
- 3.0 metre length accommodates standard building layouts
- C24 grade offers superior strength compared to C16 timber
- Check your structural design or building regulations for specific size requirements
Moisture content and storage
This timber is supplied kiln-dried (KD), meaning it has been dried to a controlled moisture content. Proper storage before installation is essential to maintain this condition and prevent warping or twisting.
- Store in a dry, well-ventilated location away from ground contact
- Keep timber covered to protect from rain and excessive moisture
- Allow timber to acclimatise to site conditions before fixing
- Avoid stacking directly on damp ground—use bearers or pallets
Fixings and installation
C24 Treated Carcassing Timber accepts standard fixings for structural applications. The regularised (planed) finish makes it straightforward to work with and provides a clean appearance.
- Use appropriate structural fixings—nails, screws, or bolts depending on application
- Ensure fixings are corrosion-resistant when used with treated timber
- Follow building regulations and structural engineer specifications for spacing and fixing patterns
- The planed finish allows for clean cuts and easy handling on site
Treated timber handling
This timber has been pressure-treated with preservative to resist rot, fungal decay, and insect attack. Handle it appropriately to maintain its protective properties and ensure safe working conditions.
- Wear gloves when handling treated timber to minimise skin contact with preservative
- Avoid inhaling dust when cutting—use appropriate respiratory protection if needed
- Dispose of offcuts responsibly; do not burn treated timber
- Wash hands and exposed skin after handling
