Fixing and buying guide
6.0Mtr X 47 X 175mm C24 Treated Regularised KD Carcassing Timber
Selecting the right size
This 47 × 175mm 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 determining whether this section meets your structural needs. C24 timber offers enhanced strength compared to C16 grade, making it suitable for applications requiring greater load-bearing capacity.
- Check your building design or structural engineer's specification for required timber grade and section size
- Verify that 6.0 metres is the correct length for your application; longer lengths may require additional handling equipment
- Confirm the regularised (planed) finish is appropriate for your end use
Understanding the treatment
This timber is pressure-treated with preservative to protect against rot, fungal decay, and insect infestation. The treatment provides long-term durability, particularly in damp or exposed conditions. Treated timber is suitable for both internal and external applications, though you should still follow good building practice regarding ventilation and moisture management.
- Treated timber is suitable for use in contact with the ground or in high-moisture environments
- The preservative treatment is integral to the timber and does not require additional on-site treatment
- Handle treated timber with standard safety precautions; avoid prolonged skin contact with sawdust
Storage and handling
Store timber in a dry, well-ventilated location to maintain its condition. Protect it from direct weather exposure and ensure air can circulate around stacks to prevent moisture accumulation. Handle with appropriate lifting equipment for longer lengths to avoid damage and ensure safe working practices.
- Stack timber horizontally with spacers between layers to allow air circulation
- Keep timber off the ground using bearers or pallets
- Protect from rain and direct sunlight during storage
Fixing methods
C24 Carcassing Timber is typically fixed using standard carpentry methods appropriate to its application. For floor joists and structural work, use galvanised or stainless steel fixings to prevent corrosion and ensure compatibility with the treated timber. Consult your structural design or building regulations for specific fixing requirements.
- Use corrosion-resistant fixings (galvanised or stainless steel) to avoid reaction with the timber treatment
- Follow your structural design for spacing, fixing centres, and connection details
- Ensure fixings are appropriate for the load and application
