A fence that covers long distances for less
Barbed wire is steel wire twisted in pairs, with sharp barbs fixed at regular intervals. Because it uses less material than mesh, it is the lowest-cost way to enclose a large perimeter. For farmers with several acres to protect, that difference is large.
It will not stop a determined intruder on its own, and it is not the right choice where children or the public pass close by. For stray cattle, goats, grazing animals and casual trespass on open land, it does the job well.
Where it is used
- Agricultural land, orchards, tea, coffee and rubber plantations
- Grazing land and cattle farms, where closely spaced lower strands keep animals in
- Open industrial or institutional land that needs a boundary before a permanent wall is built
- Top of a chain link fence or compound wall, as an added deterrent
Straight line fencing and Y-arm fencing
Straight line on RCC posts
Barbed wire runs horizontally between upright concrete posts. Lower strands are spaced closer to stop animals, with wider gaps higher up. This is the usual farm fence.
Y-arm on walls and posts
Angled Y-shaped arms are fixed on top of a compound wall or post and carry three to five strands leaning outward. This adds height and makes climbing over the wall harder.
How we build it
- RCC line posts set in concrete footings at even spacing
- Heavier corner, end and gate posts, each braced with a strut
- Galvanised barbed wire strained with a tensioning tool, so strands do not droop
- Lower strands set close enough to block calves, goats and dogs
- Gate gaps and water channel crossings planned with you before work begins
Need more protection later? A barbed wire fence can be upgraded. We can add chain link mesh between the same posts, so your first investment is not wasted. See chain link fencing.
Frequently asked questions
How many strands of barbed wire do I need?
For most farms we recommend four to seven strands. Fewer strands suit a simple boundary marker; more strands suit grazing animals or land near a road. We suggest a number after seeing the site.
Is barbed wire fencing suitable for goats and cattle?
Yes, with the lower strands spaced close together. For small goats and lambs we often recommend adding a lower mesh section or choosing chain link instead.
How long does a barbed wire fence last?
Galvanised barbed wire on RCC posts lasts many seasons. Life depends on the galvanising, rainfall and nearby salt air. Near the coast we suggest heavier galvanising or switching to PVC coated mesh.
Can you fence by the acre?
Yes. Give us the acreage or the number of cents and the shape of the plot, and we will estimate the running length before we visit. See our farm fencing page for a quick guide.
