The wire component represents approximately 50% of the cost of a fence. Consequently it is important that the correct type of wire is used to achieve stock control at the most economical cost, but at the highest quality. This will ensure that maintenance costs over the lifetime of your fence will be minimal.
Fence droppers perform three functions. They act as a wire spacer, distribute shock loads to the whole fence from individual wires and act as a visual barrier. With droppers, (approximately 1/3 the cost of steel posts) it is obvious that where they can be substituted, considerable savings can be achieved. When using droppers, it is important to ensure that droppers remain clear of the ground so that stock pressure is not taken by the dropper but by the wire component and the strainer assemblies.
Most prefabricated fence styles feature horizontal line wires joined to vertical picket wires via either a hinge, a ring, or wire knot. Because all line wires are run out together, prefabricated fencing offers considerable time saving during erection.
A good fence is an investment. Designing your fence correctly before you start and using the right materials will help to maximise the value of your investment over the life of the fence. However, even the very best fences will require some maintenance to ensure ongoing peak performance.
There are factors outside of your control that will require attention over time. Environmental conditions like floods, fallen branches and stock related wear and tear are all issues that can impact a fence’s performance
1. Check regularly
Walk or drive along your fence lines regularly to check for fence line failure points. Most maintenance can be done on the spot using tools and accessories.
2. Clear along fence lines
Remove any debris or fallen tree branches on or around your fence line. The debris that is left behind from storms and floods can become entangled on your fence. Left unattended over time, wet waste can affect the coating of your wire and posts, causing rust or corrosion, or provide a way over the fence for feral animals. Remove or trim grass that grows up around the posts and wire along your fence. It promotes good air circulation to keep the steel surfaces dry, slowing the effects of corrosion. It also reduces the combustible material around the post in the event of a grass fire, reducing the chance of extreme heat damage.
3. Repair erosion points
After heavy rain, check that soil erosion under your fence does not compromise your boundary and let stock out or feral animals in.
4. Check posts and wire tension
Straighten or replace broken posts with the same or stronger posts. Over time, things like stock pressure, fallen tree branches and general wear and tear can also cause your wire tension relax.
There are two types of barbed wire available. These are the old 2.50mm Iowa pattern and the high tensile, either 1.57 or 1.80mm. The high tensile barbed wire can be used successfully in suspension fencing. It also offers considerable savings in freight being approximately half the weight of Iowa barbed wire.
