Product Description

Our C24 Graded 75x150mm Treated Timber (finished size approx. 73x145mm) is precision-cut, kiln-dried, and pressure-treated for superior strength, durability, and weather resistance. This premium structural timber is ideal for a wide range of construction and landscaping projects, including decking subframes, roof joists, floor bearers, wall plates, and general structural framing.

Graded to C24 strength class, this timber offers improved structural integrity over C16 alternatives, making it ideal for heavier load-bearing applications and longer spans.
