How and where to use guide
4.8Mtr X 75 X 150mm C24 Treated Regularised KD Carcassing Timber
Floor joists and suspended floors
C24 timber is commonly used for floor joists in residential and commercial buildings. The 75 × 150mm section is suitable for typical domestic floor spans when properly spaced and supported. Always refer to structural calculations or building regulations guidance for your specific span and loading conditions.
- Suitable for domestic floor joists with appropriate spacing
- Provides good strength-to-weight ratio
- Regularised finish allows for clean, flush installations
Stud walls and partitions
The timber can be used for internal and external stud wall construction. The consistent sizing of regularised timber makes it ideal for creating plumb, square walls with minimal adjustment. Ensure proper bracing and fixing according to building regulations.
- Suitable for load-bearing and non-load-bearing stud walls
- Regularised finish ensures consistent wall thickness
- Treatment provides durability in external applications
Roof battens and structural framing
C24 timber is suitable for roof battens, rafter support, and general structural framing. The strength grading ensures reliable performance under roof loads. Confirm sizing and spacing requirements with your structural design or building plans.
- Suitable for roof batten and rafter applications
- Provides reliable load-bearing performance
- Treatment protects against weather exposure
Decking frames and outdoor structures
The pressure treatment makes this timber suitable for outdoor decking frames, pergolas, and garden structures. The treatment protects against rot and decay in exposed conditions, extending the service life of outdoor projects.
- Pressure-treated for outdoor durability
- Resistant to rot and fungal decay
- Suitable for decking frames and garden structures
Installation and fixing
Fix the timber using appropriate fasteners for your application—typically galvanised or stainless steel nails, screws, or bolts for structural work. Ensure all fixings are corrosion-resistant, particularly in external applications. Follow building regulations and structural design guidance for spacing and fixing patterns.
- Use corrosion-resistant fasteners for all applications
- Follow structural design for fixing spacing and patterns
- Ensure proper support and bracing for load-bearing applications
