The type of fence post you will need to use in your electric fence system depends foremost on the purpose of the fence. There are other factors to consider as well.
Do you want to create an area where livestock will graze temporarily? Or do you want a strong, durable permanent fence to contain livestock for a long period of time?
Posts provide the backbone of your fence system. Line posts support the fence wire and keep it evenly spaced.
Corner posts (generally wood) must be set deeper than line posts to withstand the strain of supporting the fence line. Temporary or portable posts are generally smaller and lighter step-in posts.
WOOD POSTS
Even though wood posts may be the most expensive post options, a fence made only from wood posts would be considered a permanent fence.
Wood posts are recommended for high tensile fence systems and other permanent fences, especially at corners, gates and termination points where there is added strain and stress.
Wood posts can also be used along the line of the fence.
Using wood posts may seem costly at first, but with the longevity of wood fence posts, it can pay for itself over and over again.
Although Zareba® Systems does not sell wood posts, you can usually purchase these at a farm store or hardware retailer near you.
Zareba steel rod posts (rebars) are ideal for portable or temporary fencing, including rotational grazing and temporary corrals. They can also be used in line posts. Since they cannot manage any significant strain, these metal posts are for the fence line, not corners.
Fiberglass Rod Posts are ideal for portable or temporary fencing including rotational grazing and temporary corrals. They can also be used for line posts and spacers. Since these posts cannot manage heavy strain, they should not be used as corner posts of a permanent fence.
A T-Post is used with a permanent line fence. Interestingly, most T-posts are made from recycled train tracks.
They do an excellent job as in-line posts. Wood posts are still needed at the corners, due to the higher strain of the fence wires at the corners. A T-post fence would be more expensive than a Step-In Post fence, but would last longer.
Although Zareba® Systems does not sell T-posts, you can usually purchase these at a farm store or hardware retailer near you.
Step-in posts are an inexpensive option. These posts will work great as in-line posts and are constructed with hooks that will handle most poly tapes. No additional clips or insulators are usually required with these posts since they are made from products with insulation properties.
A pig tail post fence is another fencing option you might consider. The pig tail step-in post is ideal for managed intensive grazing applications. The little loop at the end of the post resembles a pig's tail, hence the name.
