Product details

Build a strong, dependable foundation for your garden fencing with a Green Treated UC4 Incised Fence Post, designed for outdoor applications where timber is exposed to ground contact and challenging weather conditions. With its substantial 100 x 100mm square profile and 2.4 metre length, this post provides reliable support for fence panels, garden boundaries and other suitable timber structures.

The UC4 (Use Class 4) preservative treatment is specifically intended for timber used in direct ground contact, where exposure to moisture and biological decay presents a greater risk than above-ground applications. This makes UC4-treated posts particularly suitable for fencing installations where part of the timber is buried or set into the ground.

An important feature of this post is its incised surface, which incorporates small cuts made into the timber before preservative treatment. These incisions help the preservative penetrate deeper into the wood, improving treatment effectiveness and providing additional protection against fungal decay and wood-destroying insects.

The green treated finish gives the timber a traditional appearance that blends naturally into garden environments. Over time, the colour will gradually weather, and the post can be finished with a compatible exterior wood treatment if a different appearance is preferred.

At 2.4 metres long, this fence post is suitable for a range of common garden fencing heights, allowing sufficient length for an appropriate below-ground installation where site conditions and fence design permit.

  • Installing garden boundary fencing

Whether you're installing a new garden boundary or replacing existing fencing supports, a Green Treated UC4 Incised Fence Post 100 x 100mm x 2.4m provides a durable, purpose-treated timber solution designed to withstand the demanding conditions associated with outdoor ground-contact applications.

As a natural timber product, colour, grain, knots, surface texture and dimensions may vary. Always use appropriate post foundations, fixings and installation depths for the fence height, ground conditions and wind exposure. Treat cut ends and any exposed untreated timber in accordance with the preservative manufacturer's recommendations. UC4 treatment improves resistance to biological decay but does not make timber completely maintenance-free or guarantee a fixed service life.
