C24 timber

C24 timber is strength-graded softwood commonly used for structural applications in modern construction. Builders choose C24 timber for roof battens, wall plates, floor joists, and framing where higher strength and durability are required. Historically, builders relied on hardwoods for similar structural work, but today C24 timber offers a cost-effective and consistent alternative. It’s available untreated or as C24 treated timber, which protects against moisture, rot, and insect attack, making it more suitable for exposed or damp environments.

You can find C24 timber products in a wide range of sizes, with major suppliers like Lords and Travis Perkins stocking a variety of standard lengths. Many builders use C24 timber joists for floors and decks where structural integrity is critical. Whether you are constructing roof structures, extensions, or new builds, sourcing the right grade and treatment ensures compliance with UK Building Regulations.
