Treated Structural Timber – 47 mm × 125 mm (approx. 5″ × 2″), 4.2 m

This 47 × 125 mm treated softwood timber in a 4.2 m length is strength-graded to C16/C24, kiln-dried, and pressure-treated for reliable structural performance and long-term durability. The wide 5″ × 2″ profile and structural grading make it ideal for demanding load-bearing applications such as floor joists, roof rafters, stud walls, and decking subframes. The timber is regularised and planed with eased edges, giving consistent dimensions, smoother handling, and a neat finish that’s easy to cut, fix, and assemble on site. Preservative treatment protects against rot, fungal decay, and insect attack, making it suitable for internal structural framing and protected or above-ground external use.
