Product Information
Full details
This C24 grade sawn treated timber is designed for professional builders and DIY enthusiasts tackling heavy-duty structural applications like roof spans and floor joists. Its primary benefit is superior structural stability and long-term resistance to decay, thanks to kiln-drying and Tanalith E pressure treatment; however, users should note that the 6-meter length requires significant logistical planning and specialized transport to handle safely.

FAQs
What does C24 grade mean?
C24 is a strength class that indicates the timber meets higher requirements for strength, density, and stiffness compared to standard C16 timber.
Can I use this for outdoor projects?
Yes, the Tanalith E pressure treatment makes this timber resistant to rot, making it suitable for exterior structural use.
Do I need to treat the ends after cutting?
Yes, cutting exposes untreated wood, so you must apply a high-quality end-grain preservative to maintain the rot-resistant properties.
Can this be used for decorative flooring?
No, this is structural timber. It is not graded or finished for aesthetic floor boards.
How should I store these if I cannot use them immediately?
Keep them stacked flat on level supports in a dry, ventilated area, ensuring they are kept off the ground.
Troubleshooting
Board appears slightly bowed upon delivery
Timber is a natural product and may move; once properly fixed into a structural frame, the bowing will be corrected by the structure.
Visible surface splits or checks
Small surface cracks are normal in large-section timber due to the drying process and do not typically affect structural capacity.

Setup, Compatibility & Care
- Handling: Due to the 6m length, ensure you have a clear site path before delivery and at least two people to lift the beams to prevent bending or injury. 2. Cutting: Always retreat any cut ends with an appropriate end-grain wood preservative to maintain the integrity of the pressure treatment. 3. Fixing: Use structural-grade screws or galvanized coach bolts designed for 47mm thick timber to ensure connections remain secure as the building settles. 4. Storage: Store flat on level bearers off the ground in a well-ventilated area. Avoid placing them directly on soil or wet concrete to prevent uneven moisture absorption.
