The Brown Incised Fence Post UC4 Treated Timber (100mm x 100mm x 1800mm) is an FSC-certified softwood post engineered for permanent ground-contact applications.

Pressure-treated to UC4 standards, this heavy-duty timber resists rot, fungal decay, and wood-boring insects, making it ideal for fencing, decking substructures, and landscaping projects. The mechanical incising process ensures uniform absorption of copper-based preservatives, complying with BS 8417 certification for treatment quality.

Kiln-dried to ≤28% moisture content prior to treatment, the timber minimises warping and maximises durability in damp or soil-embedded conditions.

With a robust 100mm x 100mm cross-section and 1800mm length, this post suits high-strength applications like livestock fencing, gate supports, and retaining walls. The FSC certification guarantees responsibly sourced timber, while the brown finish integrates naturally into outdoor environments. Pre-drilled holes simplify installation, and compliance with UK building regulations ensures structural reliability.
