It is used to construct less expensive fencing and is used atop walls to protect property. It effectively provides safety from cattle and other animals at ultra low cost. Barbed wire fencing requires only fence posts, wire and fixing devices such as staples or clips. It is simple to construct and quick to erect and easy to install even by a semi skilled person.
