Strong, versatile and suitable for a wide range of outdoor construction projects, 3 x 2 Inch Green Treated UC3 Timber provides a practical solution for timber framing, garden structures, fencing supports and general building work. Its pressure-treated finish helps protect the wood against biological deterioration, making it particularly useful for exterior applications where the timber is exposed to the weather but remains above ground.
With finished dimensions of 47mm x 75mm and a generous 4.8m length, this timber offers a useful balance of strength, workability and versatility. The rectangular profile makes it suitable for constructing frameworks, supporting lightweight structures and creating timber components for a variety of domestic and professional projects.
The UC3 treatment classification indicates that the timber is intended for above-ground applications where exposure to moisture and weathering may occur. The preservative treatment helps protect against fungal decay and wood-boring insects, supporting a longer service life when the timber is correctly specified, installed and maintained.
Its characteristic green treated appearance comes from the preservative treatment process and may gradually weather to a more natural grey tone over time. The timber can be cut, drilled and fixed using conventional woodworking tools, making it suitable for builders, landscapers, fencing contractors and DIY enthusiasts.
The 4.8m length is particularly useful for larger projects where longer continuous sections are required, helping reduce the number of joints and connections needed in suitable framework applications.

For constructing garden frameworks, supporting outdoor features and completing general timber projects, 3 x 2 Inch (47mm x 75mm) x 4.8m Green Treated UC3 Timber offers a versatile, preservative-treated material for above-ground exterior use.
Important: UC3 timber is not intended for direct ground contact or permanent immersion in water. For fence posts, ground-contact supports and similar applications, use appropriately specified UC4 treated timber. Treat cut ends and drilled areas with a suitable end-grain preservative in accordance with the manufacturer's guidance. Timber is a natural material, so variations in grain, knots, colour and minor dimensional movement may occur. Structural suitability depends on the timber's declared strength grade, span, loading and fixing requirements; UC3 treatment alone does not establish structural strength.
