Gaucho(R) barbed wire is made of high tensile steel wire with a round barb and 4-point design. It features the reverse twist design that alternates the direction of the two wires at the barbs to reduce sagging, eliminates the need for pre-stretching, and allows for increased post spacing. Gaucho(R) products come in Class 3 (heavy coat) galvanized which is proven to last two to three times longer than Class 1. | Bekaert 15.5 Gauge High Tensile Barbed Wire | Size 1320'
