1/2"x1/2" welded mesh, 19 gauge, 36"x100', Black Vinyl Coated (VC) mesh - 19 gauge Galvanized After Weld (GAW) core wire is welded into 1/2" square mesh, then coated with a protective layer of Black PVC, tightly bonded to the wire. The entire mesh is thoroughly sealed and protected against rust and corrosion. This material will last! It is lighter in weight and strength than the 16 gauge 1/2"x1/2" mesh and therefore costs less. Particularly useful for animal enclosures, barriers for excluding small nuisance animals or other applications where a light mesh, rust prevention and long life are desired. It can be used as low cost flooring for chukar pens, though we recommend the heavier 16 gauge material. It is also ideal as an underground barrier, preventing gophers from burrowing to the surface under lawns.
