Ensure your fence stands the test of time with our UC4 Pressure Treated Fence Posts. Unlike standard timber, our UC4 posts undergo an intensive high-pressure treatment process designed specifically for wood in permanent contact with the ground. This provides the highest level of protection against rot, decay, and wood-boring insects. FSC Certified and kiln-dried prior to treatment to ensure maximum preservative penetration, these posts are the professional choice for agricultural, commercial, and high-end residential fencing.

Key Features & Benefits
UC4 Rated for Ground Contact: Specifically treated to endure constant moisture and soil contact, significantly outlasting standard UC3 treated timber.
FSC Certified: Responsibly sourced from well-managed forests, providing peace of mind for eco-conscious builders.
Kiln-Dried Treatment: Posts are dried before treatment to allow the preservative to reach the core of the timber, ensuring "heartwood" protection.
