Hardware Cloth, Square Wire Mesh, available in a a welded or woven construction, is made of high quality galvanized iron wire and stainless steel wire. It is sturdy, durable and rust-resistant. Applications include screens for vents, louvers, spark arrestors, finger guards, baskets, racks, trays, cages, dehydrators and miscellaneous sheet metal fabrications. Pre-galvanized wire mesh is the most economical but is more prone to corrosion because the galvanized surface is burned off where the wires are welded. However, pre-galvanized is more attractive in appearance than hot-dip galvanized.
