C24 Timber Joists UC2 Treated Kiln Dried Regularised PEFC 44 x 220mm

Treated C24 is a structural timber that's commonly used for stud walls, roof and floor joists, and structural joinery. The use of C24 grade timber, which has a smaller cross section, allows for higher loads, and longer spans. C24 grade has fewer weaknesses and knots than C16, so is stronger with a higher point load. It is machined to have rounded edges, smooth faces and sides, for a more uniformed piece of timber. It is also kiln dried to minimise moisture content and improve strength and stability, as well as pressure treated with preservatives to improve rotting resistance.
