3x2 Tanalised Timber C24 (75mm x 47mm) – A high-strength, pressure-treated timber ideal for structural use. The C24 grading means it’s stronger and more reliable than standard C16, making it suitable for load-bearing applications such as joists, framing, decking subframes, and outdoor projects. Treated to resist rot and decay, it’s durable, versatile, and built to last.
