• Floor joists — deep 225mm section handles medium spans with minimal deflection
• Roof rafters and ridge boards — C24 grading meets structural engineer specifications
• Stud walls and timber framing — consistent sizing speeds up on-site assembly

Why Choose This Product

MDM Timber’s C24 Treated Timber 9″ x 2″ (47 x 225mm) 3.6m delivers the strength, consistency, and certification that structural projects demand. C24 grade timber is slower-grown and denser than C16, with fewer knots and imperfections — meaning greater load capacity and longer achievable spans, often with a smaller cross-section. Kiln-drying controls shrinkage on site, while factory-applied pressure treatment eliminates the need for additional preservative coats. FSC certification satisfies planning and sustainability requirements. Suitable for both trade quantities and single-length orders.
