Designed for professional builders and DIY enthusiasts, this C16/C24 Sawn Treated Timber is the ideal structural solution for residential floors, roof rafters, and wall framing. Its primary benefit is its high-strength grading and pressure-treated durability, which ensures long-term structural integrity and resistance to pests or rot. A notable caveat is that while the timber is pressure-treated for longevity, it remains a natural wood product that requires proper storage away from direct moisture before installation to prevent warping.

While the Tanalith E treatment provides protection, it is not recommended for direct, permanent contact with soil or standing water.
Kiln-drying removes excess moisture, which makes the wood less likely to shrink, twist, or warp after installation.
Yes, any freshly cut end-grain should be sealed with an appropriate wood preservative to ensure the protective chemical barrier remains intact.
This timber is graded for structural framing. While it can be used outdoors in protected structures, it may require a surface finish or sealant if used for aesthetic furniture to prevent surface weathering.
The timber is regularised to 47mm x 100mm, meaning it is planed to consistent dimensions, though minor variations within industry tolerances are standard.
This is normal due to the pressure-treatment process; stack the timber with spacers in a dry, well-ventilated area for a few days to allow it to acclimatize before use.
Use high-quality wood screws and pre-drill pilot holes to prevent splitting, especially when working near the ends of the board.
For optimal results, ensure the timber is stored in a dry, ventilated area, raised off the ground using timber bearers to prevent moisture absorption. When cutting the timber on-site, it is essential to re-treat any exposed raw ends with a suitable end-grain wood preservative to maintain the integrity of the pressure treatment. Avoid using these boards in direct contact with standing water or permanent soil immersion, as they are best suited for structural framing rather than direct earth-retaining walls.
