This type of fence often comprises of Barbed wire that is stapled onto CCA treated poles. The barbed wire specifics can vary from gauge 8 to 16. However, for a long term fence we advocate for the 12.5 gauge. If gauge 16 is to be used the pole spacing will have to made smaller and preferably not more that 3 meters (10 feet), while the wire spacing should not be more that 6 inches apart. See pictorial.
