Welcome to the CMC Southern Post Online Fence Builder. Here, you can find information about the CMC Southern Post fencing products, as well as an online estimator to help determine your material needs.

Barbed Wire, Electric Wire, and Field Wire Fencing are among the most popular fencing applications that CMC Southern Post fence posts are used for. Almost any fencing application can use one of these three types of fencing.


As with any project, the planning stage is often considered the most important part. This is especially true with fencing. Without proper preparation and planning, the best intentions can be turned to ruin.

The first stage of planning the fence is to sketch a map of the area. Aerial photos are good sources to find the layout of the land. After drawing the land, mark all the areas that will need to accomidate special fencing needs. Establish the permant roads, lanes, gates, and property lines on the map. After all of these locations are established, draw the desired fence on the map.

Next, select the type of fencing desired. There are four major types of fencing, all with their own pros and cons.

Barbed Wire

These fences usually consist of three to five strands of barbed wire. The barbs on the wire can harm many of the more active livestock, such as pigs, horses, sheep, goats, etc. Therefore, it is recommended that barbed wire only be used for cattle containment and property line marking. It is less expensive to build compared to other fence types and ideal for long distances.


High Tensile Wire Fences

These fences are less damaging to the livestock they contain. They are typically used for cattle, hogs, horses, mules, corrals, and other game. Sometimes they are electrified for even better livestock containment. They are typically lower cost, compaired to other fence types, but require permanent in-line stretchers and springs. High-Tension Wire Fences are designed to withstand the impact of active livestock and then recover to its original state.

Electric Fences

These fences are ideal for most types of livestock. They can be built for temporary or permanent use. They require special electric controllers and mounting clips, which help with the visiblity of the fence. Livestock will be able to see the fence more readily, which will allow the fence's mobility to be even more effective. These fences are typically used for cattle, hog, goat, horse, mule, sheep, poultry, and other game.

Field Fences

These fences are also ideal for most types of livestock. They can be used for cattle, hog, goat, horse, mule, sheep, poultry, and other game. They also do not injure the more active livestock, like barbed wire does. They are also well suited to smaller animals because of the vertical and horizontal wire.

After the fence type has been selected, the type and number of fence posts should be figured. Our online fence estimator will aid in determining the number and type of fence posts needed in your application. The typical installation will consist of a combination of corner, line, and anchor posts.

After the posts have been selected, the amount of wire needs to be figured. This will primarily be determined by the purpose of the fence. The number of strands required will determine the amount of wire needed for your fence.


Tools And Supplies

After obtaining the appropriate amount of fence posts and wire, you will need to obtain all the appropriate tools and supplies for building the fence.


Major Tools Needed
  1. Tubular Post Driver
  2. Wire Cutters
  3. Wire Dispenser
  4. Wire Strecher


Supplies Needed
  • Fence Posts - Corner, Anchor, and Line.
  • Fence Wire
  • Fence Post Caps - For Livestock Protection Against Posts (If applicable).
  • Wire Clips - For Attaching Wire To Posts
  • Wire Energizer - For Electric Fences (If applicable).
  • In-line Tensioners - For High Tensile Fences (If applicable).



First, install the anchor and corner posts. The anchor posts on the tops of all rises and the bottoms of all dips. If the fence curves more than 10 degrees, an anchor post will be needed. Also, anchor posts will need to be placed after a certain distance. That depends upon the type of fencing and the type of posts.


Barbed Wire
For barbed wire, begin stringing wire from the top down. Make sure to remove the barbs from any gate post or anchor post. After the wire has been strung along the fence, tighten it to the appropriate tension before permanently attaching it with clips.


High Tensile Wire
This type of fencing requires special anchor bracing. Normal anchor posts will easily be pulled out by this type of fencing. A super strong, double H-brace is usually required. After the posts have been set, string the wires along the posts. Then, install the in-line tensioners and spacers.


Electric fences do not require near as many anchor posts. After the posts are installed, special insulator clips are required to prevent shorts. Also, a wire energizer will need to be installed. There are many different types to choose from, depending on the application.


Field Fencing

Unroll the fence wire along the posts. Then, attach it to the posts with the wire clips.



Caring for the new fence is very simple. Depending upon the type, the fence will need to be restreched once or twice a year. Also, unlike other fence post products, the posts will not deteriorate or rot away. They will only need to be repainted if the paint is scratched off.
