Treated Timber 7ft Fencing Pole, 4-5″ Top Diameter, CCA Treated

7ft Treated Fencing Pole

The Treated Timber 7ft Pole provides a robust solution for permanent fencing and agricultural boundary marking. These timber members undergo high-pressure treatment to withstand fungal decay and termite infestation in heavy ground-contact applications. Contractors use this specific 4-5 inch top diameter specification for structural stability in perimeter security and livestock containment projects.

Built for the Job

Standard site requirements for security fencing or agricultural paddocks demand materials that resist environmental degradation. This timber post is sourced from mature eucalyptus or pine, ensuring high fiber density and straightness. The 7-foot length allows for a standard burial depth of 2 to 2.5 feet, leaving a visible fence height of approximately 4.5 to 5 feet, which is standard for most residential and farm boundaries. The tapered profile ensures that the base of the post is wider than the 4-5 inch top, providing a lower center of gravity and better resistance to lateral wind loads or animal pressure.

• Installation of chain-link or barbed wire perimeter fencing for commercial properties.

• Structural support for agricultural netting, vineyard trellising, or shade cloth.

• Boundary demarcation for large scale land developments and construction sites.

On-Site & Workshop Notes

• Always wear gloves and respiratory protection when cutting or drilling treated lumber to avoid contact with preservative chemicals.

• If the post is cut to length on-site, apply a brush-on timber preservative to the exposed end-grain to maintain the integrity of the rot protection.

• For maximum stability in soft soil, use a concrete collar around the base of the upright member during installation.

• Store horizontally on a flat surface if not installing immediately to prevent warping before the post is set in the ground.
