Sawn Treated Carcassing Timber 75 x 175mm (Finished Size 70 x 170mm) 4.8m is premium quality, strength-graded construction timber designed for demanding structural applications. Pressure-treated for enhanced durability and protection against rot, fungal decay and insect attack, this high-performance softwood is ideal for roof timbers, floor joists, wall framing, decking subframes, timber buildings and general construction projects.

Manufactured from slow-grown, kiln-dried softwood and strength graded to C24, this structural timber offers higher load-bearing performance and fewer natural defects than standard C16 timber, making it the preferred choice for professional builders and structural applications where additional strength is required. The regularised finish with eased edges provides consistent sizing, making installation quicker and easier.

At Dorchester Timber, we supply quality structural timber to both trade and DIY customers. We also offer a professional timber cutting service to help reduce waste and make your project easier, along with reliable local delivery across Dorchester, Weymouth, Bridport, Blandford Forum, Poole, Bournemouth and throughout Dorset.

Whether you’re building an extension, garden room, timber frame, decking or roofing project, our C24 treated carcassing timber delivers the strength, stability and reliability you need.
