All About Fence Posts
There are several factors that will determine which type of fence post you will need to use. The most important factor is the purpose of your electric fence.
Are you looking for a way to contain cows so they will graze in a specific area for a short period of time? Are you looking for a heavy duty fence that will contain livestock on a permanent basis?
Learn about the types of fence posts available. We also offer expert tips for placing your line fence posts and corner fence posts. Since they must withstand enormous tension loads, the key to constructing a solid fence starts with corner posts.
A fence made only from wooden posts would be a considered a completely permanent fence, but it would be the most expensive of the fence post options available.
Wood posts must be used for corners because of the additional stress and strain put on these posts. Wood posts for corners should be up to 60-120cm in the ground and more than 120cm in sandy or rocky soil.
Wood posts can be used for the line fence also since they are long lasting permanent posts. A fence made from wood posts is very strong and can last for generations, which, over time, may eventually help defray the cost of this type of fence.
If you want to build a temporary electric fence that will cordon off an area where livestock can graze for a short period of time, Step-In Posts would be ideal for that purpose.
Step-In Posts are inexpensive posts specifically designed for temporary fencing. These posts can handle regular wire, Polywire, Polyrope and Polytape.
A round rod bar made of metal is another fencing option you might consider, this requires a round rod insulator to be slid onto the post at the required height or alternatively a pigtail insulator on the top of the post for a single wire system. Round rod posts are used for a temporary fence system since they cannot bear any significant strain.
These thin round metal posts would be used along the fence line with wooden posts at the corners where the strain is highest.
Be sure that you do not dig in a location that may have buried wire, gas or water lines without getting the clearance to dig.
Corner posts of an electric fence system should be wood posts. These wood posts should have at least a 15cm diameter. One end of the wood posts should be placed 1-1.3m into the ground.
The corner posts take tremendous tension loads and are the key to a solidly constructed electric fence. Long runs of multiple-wired fences also need brace posts along the line of fence. Bracing the corners and brace posts help dramatically increase the strength of the corners and fence. See corner post line art for image.
Temporary or portable posts are usually lighter and smaller.
FAQs about Fi-Shock™ Posts
Q: How deep should I put the wood posts?
A: In sandy or rocky soil the posts need to be deeper than in clay or dirt. Also, the amount of tension on the wire at the corner will determine the depth as well. Another factor is if the corner posts have brace posts to support them. A depth of 1-1.3m will usually be sufficient.
Q: Can I make a fence for my garden using just step-in posts?
A: The corner posts take on the most tension and even the smallest areas pull the corners in. In very small areas, a step-in post will work; however, in most areas, a T-Post or a wood post will be needed for a garden.
Q: How do I drive a T-Post into the ground?
A: Some people use a large hammer, but this is challenging and not recommended. You can purchase a "post pounder" from the same source where you buy your electric fence supplies. A heavy pipe with a closed end can also work.
Q: Which post is more durable, a T-post or a Step-In Post?
A: T-Posts are designed to be used in permanent fencing. Step-in posts are designed for temporary fencing. Although the Fi-Shock™ Step-in post is made from a specially blended polypropylene that will endure all weather types, they are still designed for temporary fencing projects.
Q: If I want to section-off an area on my farm for short-term grazing, which post is best to use?
A: The Step-in post Model A-48 or Model A-48B.
Q: How did T-posts get their name? They don’t look like a "T".
A: If you look at the top or the bottom of the post you can actually see the shape of a "T". The "U" posts look like the letter "U" from the top or the bottom but the "U" posts are not as strong as the "T" post.
