About Our Treated Timber and C24 Joists
What carcassing timber does Champion offer?
Our treated carcassing timber is straight, smooth, and consistently sized, with eased edges for easier handling. We stock C24 structurally graded timber, compliant with EN14081-2, and pressure-treated with Tanalith E for durability. Available in various sizes and lengths, our roof battens are compliant with British Standard BS5534. The 47 x 150mm C24 graded and treated timber in 4.8m lengths is also UC4 treated, making it ideal for deck joists or ground contact.
What is C24 Structural Timber?
C24 timber is a premium grade, capable of handling higher loads and wider spans due to tighter grain and less defects. This results in higher density and stability. C24 offers improved performance compared to C16 material.
What is Tanalith E?
Tanalith E is a water-based preservative containing organic biocides and it provides long-term protection against fungal and insect attacks. The process is completed using pressure cycles to ensure better penetration into the timber cells compared to brush or spray applications.
Why should I use Treated Structural Timber?
The treatment significantly extends the timber’s longevity and durability by preventing rot, decay, and insect damage, which is crucial in structural applications where failures could lead to safety hazards.
