How to Build a High Tensile Electric Fence: A Complete Guide

Building a high tensile electric fence is a comprehensive and essential process for those seeking to protect their properties, livestock, or crops. This complete guide will provide you with a detailed overview and step-by-step instructions on constructing a durable and effective electric fence system. By employing high tensile wires and reliable electric energizers, you can create a formidable barrier that effectively deters intruders and ensures the safety and security of your assets.

Is High Tensile Wire Good for Electric Fence?

High-tensile electric fencing wire is highly recommended for building an electric fence due to it’s numerous advantages. This type of wire is known for it’s strength and durability, making it a reliable fencing option. It’s designed with a high carbon content, which gives it the ability to withstand tension and prevents sagging. This is particularly important when building a long fence line, as it ensures that the wire remains tight and properly functions as a barrier.

Moreover, high-tensile wire is suitable for containing various livestock species, including exotic animals. It’s strength and electrification capability make it highly effective in keeping animals within designated areas. This is particularly crucial when dealing with large or aggressive animals that may try to break through the fence.

It’s important to consider the appropriate tension when installing high tensile barbed wire. While conventional barbed wire typically requires 300 to 350 pounds of tension, hi-tensile wire only needs between 150 to 200 pounds. Over-tensioning hi-tensile wire can lead to undesirable consequences, making it crucial to exercise caution during installation.

How Tight Should High Tensile Barbed Wire Be?

When it comes to building a high tensile electric fence, it’s important to consider the proper tensioning of the wire. One common mistake that people make is over-tensioning hi-tensile wire. Unlike traditional barbed wire fences, hi-tensile wire requires much less tension.

Typically, hi-tensile wire needs only between 150 to 200 pounds of tension. If you’re accustomed to putting up barbed wire fences, you may be used to putting around 300 to 350 pounds of tension on it. However, this level of tension is unnecessary and may actually cause damage to the hi-tensile wire, reducing it’s effectiveness and lifespan.

Firstly, it puts excessive strain on the posts and anchors, increasing the risk of the fence collapsing or becoming unstable over time. Secondly, it can cause the wire itself to stretch and weaken, which not only compromises the integrity of the fence but also increases the risk of animals breaking through.

These systems typically allow for easy adjustment of the tension to ensure that it falls within the recommended range. Furthermore, it’s important to follow the manufacturers guidelines when it comes to tensioning the wire, as different types and brands of hi-tensile wire may have slightly different tension requirements.

When it comes to durability, high tensile fencing stands strong. With a lifespan that can reach up to 40 years or even longer, this type of fencing is built to last. Regular maintenance and care are minimal, making it an ideal choice for those seeking longevity in their fencing solution.

How Long Does a High Tensile Fence Last?

High tensile fencing is known for it’s durability and longevity. When properly installed and maintained, a high tensile electric fence can last for decades, making it a wise long-term investment for any property owner. With proper treatment and care, this type of fencing can easily last for 40 years or even longer.

This makes it highly resistant to wear and tear, ensuring that the fence remains functional and effective for many years.

In terms of maintenance, very little is required to ensure the longevity of high tensile fencing. It’s important to periodically inspect the fence for any signs of damage or wear, such as broken wires or loose posts. These issues should be promptly addressed to prevent further damage and to maintain the structural integrity of the fence. In addition, regular weed trimming and vegetation control around the fence line can help prevent vegetation from interfering with the fence and potentially causing damage.

This typically involves the use of galvanized or coated high tensile wire, which provides additional protection against corrosion and rust. By choosing high-quality materials and treating them appropriately, property owners can ensure that their high tensile fence remains in excellent condition for many years to come.

Common Issues and Repairs for High Tensile Fencing

  • Wire breakage
  • Post leaning
  • Insulator damage
  • Tension loss
  • Gate misalignment
  • Corner brace failure
  • Vegetation encroachment
  • Animal damage
  • Faulty connections
  • Grounding issues
  • Weather damage
  • Hardware failure
  • Improper tensioning
