Strong, properly treated fence posts are essential for creating a stable and long-lasting garden boundary. The Brown Treated UC4 Incised Fence Post 100 x 100mm x 1.8m is designed for outdoor fencing applications, combining a substantial square timber profile with preservative treatment suitable for direct ground contact.
Manufactured from timber treated to UC4 (Use Class 4) requirements, this fence post is intended for installations where the wood is exposed to ground moisture and conditions that can encourage fungal decay. UC4 treatment provides a higher level of protection than standard above-ground timber treatments, making it particularly suitable for fence posts that are buried or set into the ground.
The post features an incised surface, with small cuts made into the timber to help the preservative penetrate more effectively during treatment. This process improves preservative penetration, particularly in timber species that can be difficult to treat, helping provide greater protection against fungal decay and wood-destroying insects.
Its brown treated finish offers a traditional timber appearance that blends naturally with wooden fence panels, garden gates and landscaped surroundings. The colour provides an attractive alternative to green treated timber and will gradually weather when exposed to outdoor conditions.
Measuring 100 x 100mm with a 1.8 metre length, the post is a practical choice for suitable lower-height fencing installations, garden boundaries and other outdoor timber projects where a substantial supporting post is required.

As a natural timber product, colour, grain, knots, surface texture and dimensions may vary. Always select an appropriate post length, installation depth and foundation method for the intended fence height, ground conditions and wind exposure. Any cut ends or exposed untreated areas should be treated in accordance with the preservative manufacturer's recommendations. UC4 treatment improves resistance to biological decay but does not eliminate the need for inspection and maintenance.
