High tensile fencing is made from high carbon steel with a carbon content of .28%. High carbon wire will stretch 4% before breaking and will not sag as much as low carbon wire. If installed properly, high carbon wire provides a maintenance free fence requiring no additional re-stretching. Because high tensile fence has a higher breaking strength, your project will require fewer posts spaced at greater distances, again helping you save money.
Traditional fencing is made of low carbon steel with a maximum carbon content of .10 percent. Low carbon wire is easy to work with and fairly forgiving as it will stretch 11 to 14 percent before breaking. It is, however, prone to sagging, stretching and elongation over time.
