12-1/2 gauge, 1-1/2"x1-1/2" welded mesh, Black Vinyl Coated (VC) mesh and fence - 12-1/2 gauge galvanized wire is welded into a strong, smooth mesh, then coated with a thick layer of PVC. The vinyl is tightly bonded to the wire. The coating will not crack when the wire mesh is bent and will resist scraping and abrasion. The vinyl effectively seals the wire from moisture and corrosive elements. UV inhibitors retard degradation from sunlight. This VC mesh and fence is not only attractive, but also will last the longest. This is the same wire used in making lobster traps.
