How and where to use guide
3.0Mtr X 47 X 200mm C24 Treated Regularised KD Carcassing Timber
Structural applications
The C24 strength grade and regularised finish make this timber ideal for primary structural elements. It is commonly specified for load-bearing applications where reliability and long-term performance are critical.
- Floor joists in residential and light commercial buildings
- Roof battens and structural roof elements
- Stud walls and partition framing
- Decking frames and outdoor structural supports
- General construction and carpentry work
Indoor construction
Within buildings, this timber performs well in areas subject to normal moisture levels. The treatment provides protection against fungal decay and insect damage, making it suitable for basements, cellars, and other potentially damp internal spaces.
- Ideal for floor joists in ground-floor and suspended timber floors
- Suitable for internal stud walls and partition framing
- Appropriate for roof structures and attic spaces
- Treatment provides protection in areas with higher moisture risk
Outdoor and exposed use
The pressure-treated preservative makes this timber suitable for outdoor applications where it will be exposed to weather and moisture. It resists rot and decay, extending service life in demanding external conditions.
- Decking frames and structural supports for outdoor platforms
- Garden structures and raised beds
- Fence posts and structural framing
- Outdoor pergolas and shade structures
- Any application where timber is exposed to weather or ground contact
Strength and performance advantages
C24 timber offers measurable performance benefits over lower grades. Its enhanced strength, reduced knot content, and improved stability make it the preferred choice for applications where structural reliability is paramount.
- Superior load-bearing capacity compared to C16 timber
- Fewer and smaller knots result in more consistent strength
- Better dimensional stability reduces movement and cracking
- Meets BS EN standards for structural timber applications
- Suitable for longer spans and heavier loads than lower grades
Compliance and standards
This timber meets current British and European standards for structural softwood. It is suitable for use in building projects subject to Building Regulations and structural design requirements.
- Strength-graded to C24 standard
- Pressure-treated for durability and rot resistance
- Meets BS EN standards for structural timber
- Suitable for use in Building Regulations-compliant construction
- Verify specific requirements with your structural engineer or building control
