47mm x 200mm Sawn Treated Timber C24 (8" x 2") 4.2m

C24 strength-graded structural softwood, kiln-dried, regularised, and treated for demanding applications in large-span floors, load-intensive roofs, and primary structural beams.200mm width in a 4.2m length carries heavier imposed loads in floors and decking, reducing bounce and movement with fewer joints across larger spans.
