1/2"x1" welded mesh, 16 gauge, 36"x100', Galvanized After Weld (GAW) wire mesh and fence - 16 gauge wire is welded into a strong, smooth mesh, then dipped into a bath of molten zinc. The entire mesh, including the welded areas, is thoroughly sealed and protected against rust and corrosion. Because it is covered with so much more zinc than Galvanized Before Weld (GBW) wire, it will last years longer. This mesh and fence is particularly useful for animal cages and enclosures, or other applications where rust prevention and long life are desired. It is ideally suited for use as ground wire for bird pens, rabbit cages - any application where a strong, long lasting, predator resistant mesh is required.
