Stainless steel mesh is the mostpopular woven in the industrial word. Welded meshes are not woven, but rather the wires are joined by resistance-welding which results in strong, consistent welds which use no filler metal in the joints. IT is used when a non-toxic and non-fraying material with a larage open is repuired. The smallest hole size is about1/4inch. These meshes have square opening straight through openings. Stainless steel wire mesh contains chromium and nickel in addition to steel. It is non-magnetic in the annealed condition.
