What it's used for

  • Closeboard and panel fence post installations for garden and boundary fencing
  • Feather edge and agricultural fencing in rural and farm settings
  • Gate posts for timber field gates and garden gates
  • General outdoor construction where timber requires direct contact with the ground

Fitting and handling

Before installation, store posts off the ground on bearers in a covered or well-ventilated area to prevent moisture uptake. When setting posts, aim to bury at least one third of the total post length, either concreted into a post hole or set with a steel fence spike on firmer ground. Any fresh cuts made on site should be treated with a suitable end-grain preservative to maintain the UC4 protection at the cut face.

FAQ

What does UC4 mean on a fence post?

UC4 is a use class rating that confirms the timber has been treated to withstand direct contact with the ground. It offers a higher level of preservative protection than UC3 timber, which is only rated for above-ground outdoor exposure. For fence posts set into soil or concrete, UC4 is the correct specification.

What length fence post do I need for a 6ft fence?

For a standard 6ft (1.8m) fence, a 3.0m (10ft) post is typically recommended. This allows roughly 600mm to 750mm to be set in the ground while leaving adequate height above ground to fix the fence panels or boards. On softer ground, the 3.6m post gives additional depth for a more secure footing.

Can I cut a UC4 treated fence post to length?

Yes, UC4 posts can be cut on site. However, cutting exposes untreated timber at the sawn end. Apply a brush-on end-grain preservative rated for ground contact to any fresh cuts before installation to maintain rot resistance at that point.

Good quality, but a few issues with the hidden mounts and levelness.
Size: 35x7 2Pcs, Color: Black, Size: 35x7 2Pcs, Color: Black
These are quite nice and also sturdy. Only complaint I have is that I bought a couple of these, and on one of them, only one of them, it was difficult to get the hidden mounts to go into the holes. I think it was probably a manufacturing defect thing. Also, on that particular one, it wasnt as level as the other. Not a show stopper, but if you need a perfectly level type of mounting situation, I would be careful here.
