Fixing and buying guide
6.0Mtr X 47 X 225mm C24 Treated Regularised KD Carcassing Timber
Selecting the right size
This product is supplied as 6.0 metre lengths with a cross-section of 47 × 225mm. Verify your project requirements against these dimensions before purchase. C24 timber is suitable for floor joists, roof battens, stud walls, and decking frames. Check your building plans or structural engineer's specifications to confirm the correct section size for your application.
- Confirm length and cross-section match your project requirements
- C24 grade provides superior load-bearing performance compared to C16
- Regularised finish means consistent sizing across all pieces
Storage and handling
Treated timber should be stored in dry conditions to maintain its properties. Stack pieces horizontally with spacers between layers to allow air circulation and prevent moisture accumulation. Protect from direct ground contact and prolonged exposure to standing water.
- Store in a dry, well-ventilated location
- Use spacers when stacking to allow airflow
- Keep off the ground using bearers or pallets
- Avoid prolonged exposure to standing water
Fixing and installation
Use appropriate fixings for your application. For structural work, follow building regulations and any engineer's specifications. Treated timber can be fixed using standard nails, screws, or bolts. Pre-drill where necessary to prevent splitting, particularly near the ends of pieces.
- Use fixings appropriate to the application and load requirements
- Pre-drill to reduce splitting risk
- Follow building regulations and structural specifications
- Ensure adequate bearing and support at connection points
Pressure treatment and durability
This timber is pressure-treated with preservative to protect against rot, fungal decay, and insect attack. The treatment provides long-term durability for both indoor and outdoor use. The treated finish is integral to the timber and does not require additional surface treatment for protection, though you may apply finish coatings for aesthetic purposes.
- Pressure-treated for rot and decay resistance
- Suitable for outdoor and damp environments
- Treatment is integral; no additional protective treatment required
- Optional finish coatings can be applied for appearance
