Weld - Mesh Welded wire mesh is economical and ideal for many uses. The wires used in the manufacturing process are welded into a variety of mesh sizes. Different gauge wires are used. Heavier gauge wire will last longer due to the fact that it will take longer for rust to eat through the wire. The gauge and mesh sizes are determined by the final use of the product. The main surface treatments are electric galvanizing, hot-dip zinc plating, PVC coated. Galvanized weld products are made by dipping previously welded mesh into a bath of molten zinc. The entire fence or mesh, including the welded areas, is thoroughly sealed and protected against rust and corrosion. PVC coated wire mesh is coated with a thick layer of PVC which is tightly bonded to the wire by a heat process. The coating is flexible and will not crack when the wire is bent. They have double protection. Not only does the vinyl coating seal the wire from water and other corrosive elements, but the underlying mesh is also protected by a zinc coating. Stainless steel welded wire mesh is strong and long lasting. By its very nature stainless steel wire needs no additional finish, such as galvanizing or PVC, to protect it.
