How and where to use guide
4.8Mtr X 47 X 200mm C24 Treated Regularised KD Carcassing Timber
Structural applications
This timber is ideal for load-bearing structural work where strength-grading is required. The C24 classification indicates it meets specific strength standards for structural timberwork, making it suitable for applications where joists, beams, and wall frames must support significant loads. It is commonly used in residential and commercial construction where reliability is critical.
- Floor joists in residential and commercial buildings
- Roof battens and structural roof work
- Stud walls and partition framing
- Decking frames and outdoor structures
Indoor building projects
For interior applications such as floor joists, roof structures, and wall framing, C24 treated timber provides excellent strength and stability. The treatment protects against fungal decay and insect attack, which is particularly important in areas prone to moisture or where timber may be exposed to damp conditions. The regularised finish gives a clean, professional appearance suitable for visible applications.
- Residential floor joists and structural framing
- Roof trusses and battens
- Internal stud walls and partition frames
- Loft and attic structural work
Outdoor and exposed applications
The pressure-treated preservative makes this timber resistant to rot, fungal decay, and insect infestation, making it suitable for outdoor use. It performs well in exposed conditions where untreated timber would deteriorate. Common outdoor applications include decking frames, garden structures, and external building elements that require durability and long-term performance.
- Decking frames and outdoor platforms
- Garden structures and pergolas
- External building frames and cladding supports
- Fence and gate construction
Advantages over lower grades
C24 timber offers enhanced performance compared to C16 carcassing timber. It has fewer knots, improved strength characteristics, and greater stability, making it the preferred choice for applications where load-bearing capacity and long-term reliability are important. The investment in higher-grade timber often results in better structural performance and reduced risk of movement or failure.
- Superior strength and load-bearing capacity
- Fewer knots and more consistent quality
- Better stability and reduced movement
- Longer service life in demanding applications
