3.0Mtr X 47 X 75mm Treated Regularised KD Carcassing Timber
Understanding C24 grading and strength
C24 is a strength grade that indicates this timber has been tested and certified for superior load-bearing performance. It offers enhanced stability and improved strength compared to lower grades such as C16, making it suitable for structural applications where reliability matters. The timber is regularised, meaning it has been planed to consistent dimensions for easier handling and installation.
- C24 grade provides higher bending strength and stiffness than C16
- Suitable for floor joists, roof battens, stud walls, and decking frames
- Regularised finish means smooth, planed surfaces for cleaner installation
Pressure treatment and durability
The timber is pressure-treated with preservative to protect against rot, fungal decay, and insect infestation. This treatment extends the service life of the timber, particularly in damp or outdoor environments where untreated softwood would deteriorate.
- Protects against rot and fungal decay
- Resists insect attack and wood-boring pests
- Suitable for both indoor and outdoor applications
