Hardware ClothHardware cloth is a type of wire mesh that is welded and galvanized. It is an economical choice for a rust and corrosion-resistant screen that won’t oxidize. It is usually large gauge and between .25 and .5 inches thick. Hardware cloth is used for many different industrial, agricultural and commercial uses, and is part of the production of screens for vents, louvers, spark arrestors, finger guards, baskets, racks, trays, cages, dehydrators and sheet metal. Hardware cloth is available in different weave patterns, including square mesh, which may be plain or twilled, plain Dutch weave, a dense weave where the warp (vertical) wires are larger than the shute (horizontal), and reverse plain weave, where the shute wires are larger than the warp. During the fabrication process, metal wire is either woven or welded together to form a screen. Different mesh counts, which are the number of openings per linear inch, and wire diameters are used for certain kinds of hardware cloth. Each piece of wire, made of stainless steel, steel, brass, monel or aluminum, is welded together to increase strength and stabilize the crossover points. This prevents the cloth from unraveling when it is being cut. The metal cloth is then galvanized, a process where the welded steel wire is hot-dipped in molten zinc. This protects the mesh from corrosion and rust.
