How and where to use guide
4.8Mtr X 47 X 225mm C24 Treated Regularised KD Carcassing Timber
Floor joists and structural framing
The 47 × 225mm cross-section and C24 strength grade make this timber ideal for floor joists in residential and light commercial construction. Its superior load-bearing capacity compared to lower grades ensures reliable performance under typical domestic and commercial floor loads. The timber's stability and fewer knots compared to C16 grade contribute to consistent structural performance.
- Suitable for domestic floor joists with appropriate span calculations
- Provides enhanced stability for long-span applications
- Fewer knots and improved strength compared to C16 timber
Roof battens and roof structures
C24 timber is commonly used for roof battens, purlins, and other roof structural elements. The treatment provides protection in exposed roof environments where moisture exposure is higher. The regularised finish ensures consistent sizing for neat installation.
- Suitable for roof battens and purlin applications
- Treatment protects against moisture exposure in roof environments
- Consistent sizing aids neat installation
Stud walls and partition framing
For internal and external stud wall construction, C24 carcassing timber provides the strength and stability required for load-bearing and non-load-bearing partitions. The treatment is particularly valuable for external walls and areas subject to higher moisture levels.
- Suitable for load-bearing and non-load-bearing stud walls
- Treatment protects external walls from rot and decay
- Planed finish provides clean appearance for visible applications
Outdoor and exposed applications
The pressure treatment makes this timber suitable for outdoor construction including decking frames, garden structures, and other exposed applications. The preservative treatment protects against rot, fungal decay, and insect infestation, extending the timber's service life in demanding outdoor environments.
- Pressure-treated for outdoor durability
- Resistant to rot, fungal decay, and insect attack
- Suitable for decking frames and garden structures
General construction work
Beyond specific applications, C24 carcassing timber is a reliable choice for general structural timberwork where quality and durability are required. Its strength grading and treatment make it suitable for both professional and serious DIY projects.
- Suitable for general structural timberwork
- Reliable performance in both indoor and outdoor projects
- Meets structural requirements for professional and DIY applications
