A tanalised green timber fence post is a heavy-duty vertical upright used to provide upright structural support for garden fencing, gates, and outdoor boundary structures. Pressure-treated with Tanalith E wood preservative (which gives the wood its initial subtle pale green tint), it is engineered for direct ground contact to resist rot, fungal attack, and insect damage.

• Supporting Wooden Fence Panels: Set directly into the ground with concrete (Postcrete) to support lap panels, closeboard, featheredge, or decorative garden fencing.

• Gate Posts: Acts as a sturdy anchor for hanging garden gates, driveway gates, and timber side access doors.

• Garden & Agricultural Boundary Fencing: Used with timber rails, post-and-rail systems, or wire mesh for livestock, pet containment, and field perimeter fencing.

• Decking & Raised Structure Uprights: Functions as corner supports and upright posts for timber decking balustrades, pergolas, and raised garden borders.

How deep should a timber fence post be buried in the ground?

As a general rule of thumb, at least 600mm (2ft) or 1/3 of the total post length should be set below ground level. 

Do I need to treat cut ends or trimmed tops of a tanalised post?

Yes. Whenever you cut or notch a pressure-treated post, always liberally coat the newly exposed wood with a specialist end-grain timber preservative. Fitting a decorative post cap or sloping the post top also helps shed rain and prevents top-down water penetration.

Will the pale green colour stay the same over time?

No. The initial pale green tint comes from copper salts in the Tanalith E treatment. As the wood is exposed to sunlight and weather, it gradually turns a warm honey brown before seasoning to a natural silver-grey after 6 to 12 months.
