- Account for any notching or drilling requirements when ordering length
- Regularised timber has a planed finish for easier handling and installation
Understanding C24 grading
C24 is a strength grade that indicates this timber has been stress-graded to meet specific load-bearing standards. It offers enhanced stability and improved strength compared to lower grades such as C16, with fewer knots and more consistent structural properties.
- C24 timber meets BS EN standards for structural applications
- Suitable for applications requiring higher load-bearing capacity
- Provides greater reliability in demanding construction environments
Pressure treatment and durability
This timber is pressure-treated with preservative to protect against rot, fungal decay, and insect infestation. The treatment extends the service life of the timber, making it suitable for both sheltered indoor use and exposed outdoor applications.
- Treatment provides long-term protection in damp or exposed conditions
- Suitable for use in contact with the ground or where moisture exposure is likely
- Treated timber should be stored in dry conditions to maintain its properties
Storage and handling
Proper storage protects the timber's quality and treated finish. Store in a dry, well-ventilated location away from direct ground contact. Handle with care to avoid damage to the planed surface.
- Stack timber horizontally with spacers to allow air circulation
- Protect from prolonged exposure to weather during storage
- Inspect for damage before installation
