Treated Structural Timber – 47 mm × 175 mm (approx. 7″ × 2″), 4.2 m
This 47 × 175 mm C24 structural softwood timber, supplied in a 4.2 m length, is kiln-dried, pressure-treated, and regularised (planed with eased edges) to ensure reliable strength, stability, and long-term durability. Its deep 7″ × 2″ profile offers excellent load-bearing capacity and rigidity, making it ideal for demanding structural applications such as floor joists, roof rafters, beams, stud walls, and general framing. The preservative treatment provides protection against rot, fungal decay, and insect attack, ensuring the timber performs well in above-ground or covered external environments. Its smooth, planed finish ensures consistent sizing, easier cutting, safer handling, and straightforward installation.
