1-1/2"x1-1/2" welded mesh, 12-1/2 gauge, 36"x100', Black Vinyl Coated (VC) mesh and fence - 12-1/2 gauge Galvanized After Weld (GAW) 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 vinyl coating will not crack when the wire mesh is bent and will resist scraping and abrasion. This wire mesh and fence has double protection - the vinyl layer effectively seals the wire from moisture and corrosive elements and the underlying, thickly galvanized wire is a strong protective layer. UV inhibitors retard degradation from sunlight. This is the VC mesh and fence used in lobster traps and kennel flooring. It is not only attractive, but also will last the longest.
