47mm x 175mm C24 timber, in lengths of 4.2m. This C24 sawn timber is kiln dried to minimize shrinkage, twist, warping and improve stability. It’s also often pressure treated for rot resistance (e.g. with Tanalith E or similar). Sawn C24 timber is a widely used structural timber for UK construction - a high-strength structural softwood ideal for various building applications. The treatment and kiln-drying process make it suitable for both indoor and outdoor jobs, while its regularised profile gives consistent dimensions for easy use.
