Description

Decking joist kit (pack of 10): This C24 sawn green treated timber offers a strong, dependable option for constructing stable roofing frameworks or long‑lasting decking subframes. Graded to the C24 strength class, it provides excellent structural performance, giving you confidence when building bases that need to support heavier loads or span greater distances. The Tanalith ‘E’ treatment enhances durability, protecting the timber against moisture, rot, and insect attack over time.

With fewer knots and a denser grain than standard C16 timber, this profile delivers superior strength for more demanding applications. FSC® certification ensures the timber is responsibly sourced, offering reassurance for outdoor projects. When installed on a solid, level concrete foundation, these joists provide outstanding support for decking systems and can also be used for key roofing components such as rafters and purlins.

Benefits of C24 Sawn Green Treated Timber (47mm × 100mm)

  • High‑strength C24 grade ideal for decking and roofing structures
  • Tanalith ‘E’ treatment for long‑term resistance to decay and insects
  • FSC®‑certified for responsible sourcing
  • Denser grain and fewer knots for improved load‑bearing performance
  • Easy to cut, drill, and adapt for various installations

Each length is simple to work with and can be sawn, planed, or drilled to suit your project requirements. When used for decking, the timber forms the essential supporting framework beneath the boards, especially when paired with recommended posts and fixings.
