Machine Rounded Fence Posts, Chamfered Top, Green Treated or UC4 Treated, 1.2m to 2.4m, 40mm to 100mm Diameter

These machine-round timber fence posts are softwood posts turned to a consistent diameter along their length, with a chamfered top. They are sold individually and come in two treatments: Green Treated, in lengths from 1.2m to 2.4m and diameters from 40mm to 100mm, and UC4 Treated, in 1.8m lengths at 75mm and 100mm. They suit farmers, smallholders, landscapers, gardeners and anyone putting up stock, wire, rail or garden fencing.

Why it works

A consistent round profile

Machine rounding takes each post down to an even diameter, so posts of the same size match one another. That makes it easier to keep a fence line straight, to fix wire, netting or rails at a steady height and to plan quantities from a single size.

A chamfered top

Each post has a chamfered top. Whether the bottom of the post is pointed is not published for this line, so check the posts on arrival before you plan to drive them, and point them yourself if needed.

A wide choice of sizes

The Green Treated range runs from slim 40mm posts for staking and light netting up to 100mm posts for post and rail and heavier fences. Lengths run from 1.2m to 2.4m, so one listing covers short garden jobs through to taller stock and rail fencing.

Know the limits: treatment class and cut ends

UC4 (Use Class 4) is the treatment class intended for timber in contact with the ground. The Green Treated posts are pressure treated, but their use class is not published for this line. For permanent fence posts set in the ground, choose UC4 Treated where it is available in the size you need. Cutting or pointing a post exposes untreated timber, so treat all cut ends with a suitable preservative before fitting.

Where it's used

The posts are typically used for:

• Stock fencing and post and wire fencing
• Post and rail fencing, using 100mm posts
• Garden and rabbit fencing
• Tree staking and plant supports
• Supports for netting
• General landscaping work

Specifications

Choosing the right option

Choose the treatment first, then the length and diameter. The guidance below is general practice; your own site, soil and fence design may call for something different.

Treatment. For posts that will stand permanently in the ground, UC4 Treated is the class intended for ground contact and is the better choice where the size you need is offered: 1.8m at 75mm or 100mm. The UC4 options at 2.4m (75mm, 100mm and 200mm) and 3.0m × 85mm are currently unavailable. Green Treated suits the wider range of sizes, with its use class not published for this line.

Diameter. 40mm to 50mm posts suit tree stakes, plant supports, netting and rabbit or garden fencing. 60mm to 75mm posts are typical for intermediate posts in stock fencing and post and wire fencing. 100mm posts suit post and rail and heavier fences. Gate posts and strainer posts carry more load, so for those positions use bigger, purpose-sized strainer posts.

Length. Allow for roughly a third to a half of the post to be in the ground, so pick a length that leaves the fence height you need above ground.

Installation, use & care

Set out the fence line and mark post positions. For wire fences, space posts at around 2m to 3m. Shorter posts are usually driven in with a post driver; longer posts are usually set in a dug hole and backfilled firmly. Bury roughly a third to a half of each post's length. Treat any cut or pointed ends with a suitable preservative before fitting. Check posts from time to time for movement or damage and re-firm them where needed.

FAQ

What is the difference between Green Treated and UC4 Treated?

Both are treated timber. UC4 is the use class intended for timber in ground contact. The Green Treated posts are pressure treated, but their use class is not published for this line, so for permanent in-ground posts prefer UC4 where available.

Do the posts have a pointed end?

The posts have a chamfered top. Whether the bottom is pointed is not published for this line.

How deep should the posts go in the ground?

As general practice, bury roughly a third to a half of the post's length. Shorter posts are usually driven and longer posts set in a hole.

Is the 2.4m × 75mm post available in UC4?

No. The UC4 Treated options at 2.4m (75mm, 100mm and 200mm) are currently unavailable. The 2.4m × 75mm post is available in Green Treated, and UC4 Treated is available at 1.8m in 75mm and 100mm.
