ffC's long history in the livestock fence business has proven that the key to any tensioned fence is how secure the end and corner posts are. To assure a long life for your fence we use 6” x 9' treated, Southern Yellow Pine posts for this purpose. These posts are driven in the ground and are solid and secure the moment the machine backs away from the post. 5” x 8' Treated SYP posts are used as line posts, and are also driven into the ground. We recommend, and install, High Tensile, type 3 galvanized, woven wire whenever possible. These components will realistically provide a 20 – 30 year life expectancy for your fence.
