Treated Structural Timber – 47 mm × 225 mm (approx. 9″ × 2″), 4.2 m
This 47 × 225 mm structural softwood timber, graded C24 and supplied in a 4.2 m length, is kiln-dried, pressure-treated, and regularised (planed with eased edges) to deliver exceptional strength, rigidity, and long-term durability for demanding structural applications. The deep 9″ × 2″ profile provides excellent load-bearing capacity and span performance, making this timber ideal for floor joists, roof rafters, structural beams, and major framing work. The preservative treatment protects against rot, fungal decay, and insect attack, ensuring reliable performance in above-ground or covered external environments. Its smooth, planed finish and consistent sizing make handling, cutting, and installation straightforward for both professional builders and DIY projects.
