150mm x 150mm (6 x 6) - Treated Timber Fence Post UC4

150mm x 150mm (6 x 6) Treated Timber Fence Post UC4 is a heavy-duty fencing post designed for demanding outdoor applications where maximum strength and long-term durability are required. Pressure treated to Use Class 4, this post is suitable for direct contact with soil or fresh water, making it ideal for in-ground installations.

Manufactured from rough sawn softwood and engineered to achieve deeper preservative penetration, these fence posts offer enhanced protection against rot, decay, and insect attack. The UC4 treatment process allows the preservative to permeate further into the timber, helping deliver a significantly longer service life in exposed environments.

This 6x6 treated timber post is commonly used for heavy fencing, gates, boundary fencing, agricultural fencing, pergolas, and other outdoor structures where additional strength and stability are essential. The rough sawn finish provides a traditional appearance and improved grip when handling and installing.

For best long-term performance, all cut ends should be sealed with a suitable wood preservative after cutting to maintain full protection.
