Why choose Treated C24 6×2 Timber

Treated C24 Timber 6×2 (150mm x 47mm) in 4.2m lengths is a high-strength structural softwood commonly used throughout roofing, floor construction and general building work. Pressure treated for improved durability, this timber is ideal where a stronger graded section is required for dependable structural performance.

C24 timber offers a higher strength rating than C16, making it particularly suitable for demanding applications such as rafters, joists, roof structures, floor frameworks, timber framing and construction projects where increased load-bearing performance is required.

Key Benefits

• High Strength Grade: C24 graded for superior structural performance.
• Pressure Treated: Helps protect against fungal decay and insect attack.
• Ideal for Roofing: Suitable for rafters, joists and structural roof work.
• Reliable Section: 150mm x 47mm profile for strong construction use.
• Trade Ready: Supplied in practical 4.2m lengths for site work.

Where C24 Treated Timber is Used

Commonly used for roof rafters, floor joists, timber frames, structural supports, studwork, outbuildings, extensions and general construction projects. Its C24 strength grading makes it suitable for projects where a stronger structural timber is preferred over standard C16 sections.

Good Practice & Workmanship

Timber should be stored flat, raised off the ground and protected from prolonged exposure to moisture before installation. Any cut ends should be treated with a suitable end grain preservative. Structural timber must always be installed in accordance with project specifications, span requirements and relevant building regulations.
