5.4Mtr X 75 X 225mm C24 Treated Regularised KD Carcassing Timber
Structural applications
This timber is specifically designed for load-bearing structural work where strength and reliability are essential. The C24 grade indicates it has been strength-graded to meet specific performance standards, making it suitable for applications requiring higher load capacity than lower grades.
- Floor joists in residential and light commercial buildings
- Roof battens and structural roof framing
- Stud walls and internal partitioning
- Decking frames and outdoor structural elements
Indoor construction
For internal building work, C24 carcassing timber provides excellent stability and a clean, planed finish. The regularised profile ensures consistent sizing, making it straightforward to install and finish. The pressure treatment offers protection against moisture-related issues in kitchens, bathrooms, and other damp areas.
- Ideal for floor joists in multi-storey residential construction
- Suitable for internal stud walls and partition framing
- Provides reliable performance in moisture-prone areas when properly ventilated
- Smooth finish allows for direct decoration or covering
Outdoor and exposed applications
The pressure treatment makes this timber suitable for outdoor structural work where exposure to weather and moisture is unavoidable. It resists rot, fungal decay, and insect attack, providing long-term durability in demanding environments.
- Decking frames and structural supports for outdoor structures
- Garden buildings and sheds requiring structural strength
- Exposed roof battens and external framing
- Applications where timber will be in contact with soil or water
Advantages over lower grades
C24 timber offers measurable benefits compared to C16 carcassing timber. Enhanced strength, fewer knots, and improved stability make it the preferred choice for applications where performance and longevity are priorities.
- Higher load-bearing capacity allows longer spans with smaller sections
- Fewer knots and defects result in more consistent performance
- Greater stability reduces movement and potential cracking
- Better suited to applications with demanding structural requirements
