In the United States modern Barbed Wire Fence Technology is used to enclose cattle as standard. In the United Kingdom some farmers choose Barbed Wire Fencing as a practical solution to contain livestock. The wire is attached between strainer posts, pulled taut and then affixed to either existing or new steel or wooden fence posts, sometimes with battens in between.
Steel post spacing
Where the terrain is undulating with hills a farmer would normally place steel posts around 2.7 metres apart whereas on flat land the gaps between posts might be as much as 46 metres depending on the type and amount of livestock to be contained inside the barbed wire fence.
Wooden post spacing
If wooden posts are to be used, the gaps between them would normally be a maximum of 10 metres no matter the type of terrain using up to 5 battens to each gap, but many farmers prefer the space between posts to be not more than 1.8 metres since battens are prone to bending, which results in the wires becoming slack and the wires closing in on each other.
High tensile- v- mild/soft steel
The two most common Barbed Wire Fence for Agricultural purposes are high tensile or mild/soft steel. Both these products are galvanized for durability and longevity but it’s generally agreed that high tensile wire, despite being thinner, is by far the best choice. This is because the steel used in production is of higher strength making the barbed wire resistant to stretching and becoming loose. High tensile wire handles contraction and expansion well in all temperatures and copes better with the pressure of animals that relax against the barbed wire fence preventing stretching. The fence lasts considerably longer than other forms of agricultural containment fencing. Longer spans can be achieved with high tensile wire but this type of barbed wire fence should always be installed by a professional Fencing Contractor due to its elasticity. In the wrong hands this wire can be highly dangerous so to avoid accidents always use an experienced professional. Whilst mild/soft wire is simpler to work with it is not as strong and cannot accommodate long spans. It also has a shorter lifespan and is best used for repairs or on gates where it is less likely to become entangled.
How many wires?
In fertile areas where there is a high soil content and dairy herds need to be contained the barbed wire fence should be constructed with 5 to 7 wires. For sheep it Is recommend that 7 wires are used but the 2nd wire from the bottom to the 5th should be plain wire so that sheepdogs can gain access.
