Gaucho® 15.5g Barbed Wire is directly comparable to 12.5g low carbon products, but requires less maintenance and is more cost effective. Our Gaucho® 15.5g Barbed Wire is made of high strength steel wire. This means we can use a smaller diameter wire while maintaining the same strength as standard strength barbed wire. Our reverse twist design reduces sagging, eliminates the need for pre-stretching and allows for increased post spacing. All of which will save you time, money and maintenance headaches.
