75mm x 150mm Sawn Treated Timber C24 (6" x 3") 3.6m

C24 strength-graded structural softwood, kiln-dried, regularised, and treated for demanding applications in floors, roofs, and primary beams.150mm width in a 3.6m length provides solid mid-span support with fewer joints, while the 75mm thickness offers a broad bearing face for connectors and hangers, reducing bounce and flex.
