Bekaert High Tensile 4-Point Barbed Wire features a breaking strength equal to a standard 12.5ga wire, but is half the weight of a standard barbed wire. Due to the high tensile line wires used, it allows for increased post spacing up to 5in. Plus, this is a class 3 galvanized wire, which means it has 2-3 times the life expectancy of class 1 galvanization.
