Treated Structural Timber – 47 mm × 125 mm (approx. 5″ × 2″), 3.6 m
This 47 × 125 mm treated softwood timber, graded C24 and supplied in a 3.6 m length, is kiln-dried, pressure-treated, and regularised with planed faces and eased edges. Its robust 5″ × 2″ dimensions and structural-grade classification make it well-suited for heavy-duty framing, floor or roof joists, stud walls, decking frameworks, and other load-bearing constructions. The preservative treatment protects it from rot, fungal decay, and insect damage, ensuring longevity and reliability even in damp or challenging environments. Regularised sizing and smooth surfaces enable clean cuts, secure fixings, and accurate installation whether for professional building or DIY projects.
