4.2Mtr X 47 X 200mm C24 Treated Regularised KD Carcassing Timber
Floor joists and suspended floors
The 47×200mm section and C24 strength grade make this timber suitable for floor joists in residential and light commercial applications. The depth provides adequate load-bearing capacity for typical floor spans, whilst the regularised finish ensures consistent bearing on wall plates and support beams. Spacing and sizing should be confirmed against building regulations and structural design for your specific span and load conditions.
- Suitable for floor joists in residential and light commercial buildings
- Regularised section ensures consistent bearing surfaces
- Confirm spacing and sizing against building regulations for your span
Roof battens and structural framing
This timber is commonly used for roof battens, ceiling joists, and structural framing in roof assemblies. The C24 grade provides the necessary strength for typical roof loads, whilst the treatment offers protection in the roof void where moisture can accumulate. Ensure adequate ventilation in roof spaces to manage condensation and maintain timber durability.

Stud walls and partition framing
The regularised 47×200mm section is suitable for stud walls and partition framing in both load-bearing and non-load-bearing applications. The consistent dimensions aid rapid installation and ensure plumb and level construction. The treatment is beneficial in areas prone to moisture, such as kitchens and bathrooms, where durability is important.
- Suitable for load-bearing and non-load-bearing stud walls
- Regularised finish aids rapid, accurate installation
- Treatment beneficial in moisture-prone areas
External applications
The pressure-applied treatment makes this timber suitable for external structural applications where rot and decay resistance is essential. Examples include external wall framing, pergolas, and structural supports in exposed conditions. Ensure the timber is protected from standing water and that any cut ends are sealed or treated to maintain the integrity of the preservative protection.
- Pressure treatment suitable for external structural work
- Protect from standing water and prolonged moisture exposure
- Seal cut ends to maintain treatment integrity
Installation and site handling
The kiln-dried, regularised finish makes this timber straightforward to handle and install on site. Measure and cut to length as required, using a sharp saw to minimise splintering. The regularised section provides consistent dimensions, reducing the need for planing or adjustment on site. Handle treated timber with care and avoid prolonged skin contact; wash hands after handling.
