This great corral is made from galvanized steel with oval rails. We have oval railing, which the oval has a a lot more strength than a round rail when pushed down by the hoof of a horse or cattle or when a cowboy climbs over it. Because the the oval rail is flat on the sides it also flexes more when pushed against. In this package you will get 19 x panels 6ft long and 5ft 3 inches high and 1 x 6ft wide gate with adjustable 10ft top.
