Treated Timber 4-5 inch Diameter Fencing Pole, 8ft Length

8ft Treated Fencing Pole

The Treated Timber Fencing Pole provides a robust structural foundation for agricultural, residential, and commercial perimeter installations. This pole undergoes a rigorous vacuum-pressure impregnation process using Chromated Copper Arsenate (CCA) to ensure deep chemical penetration into the sapwood. This treatment level protects the wood against termite infestation, fungal decay, and various soil-borne pathogens common in high-moisture environments.

Built for the Job

Contractors and site supervisors select these 8ft posts for their consistent structural integrity and resistance to environmental stress. The 4 to 5-inch top diameter offers the necessary thickness to support heavy-duty chain link mesh or multiple strands of high-tensile electric fencing. These units are typically sourced from mature Eucalyptus or Pine plantations, ensuring straightness and high density. The 8ft height allows for a standard 2ft burial depth, providing a stable 6ft finish height above ground level.

• Installation of perimeter security fences for residential plots.

• Support structures for agricultural netting and vineyard trellising.

• Construction of temporary site hoarding for building projects.

On-Site & Workshop Notes

• Avoid cutting the buried end of this post as it exposes the untreated core to soil bacteria.

• Apply a bitumen-based sealer to the top of the timber to prevent water ingress and end-splitting.

• Ensure a minimum 600mm hole depth for adequate wind load resistance in loose soil conditions.

• Wear appropriate gloves and respiratory protection when handling or drilling these chemically treated materials.

• Store horizontally on level ground with spacers to maintain straightness before the installation process begins.
