How and where to use guide
4.8Mtr X 47 X 75mm C16/C24 Treated Regularised KD Carcassing Timber
Structural applications
This timber is ideal for load-bearing applications including floor joists, roof battens, ceiling joists, and beam work. The C24 grading ensures reliable performance under structural loads. It is also suitable for stud walls in timber-frame construction, where consistent strength and stability are essential.
- Floor joists and joist hangers
- Roof battens and rafter work
- Stud walls and timber-frame construction
- Ceiling joists and internal structural work
Outdoor and exposed work
The pressure-treated preservative makes this timber suitable for outdoor applications where moisture exposure is a concern. It can be used for decking frames, garden structures, and external cladding battens. The treatment protects against rot and decay in damp or ground-contact situations.
- Decking frames and substructures
- Garden structures and pergolas
- External cladding battens
- Applications with ground contact or high moisture exposure
Installation and fixing
The regularised finish allows for clean, straightforward installation. Use appropriate fixings for your application: galvanised or stainless steel nails and screws for outdoor work to prevent corrosion. For structural connections, follow building regulations and use joist hangers, metal brackets, or other approved fixing methods as required by your design.
- Use galvanised or stainless steel fixings for outdoor applications
- Apply joist hangers and metal brackets for structural connections
- Follow building regulations for load-bearing applications
- Ensure adequate ventilation around timber to prevent moisture trapping
