The metal mesh cover is primarily used to prevent larger foreign objects from entering the fan and causing accidents. It is mainly made of multi-faceted treated iron wire or electrolytically treated stainless steel, and is available in common colors such as black and silver-white. The iron wire mesh cover, after copper, nickel, or chrome plating, meets the requirement of 8 hours of salt spray resistance without corrosion. The stainless steel, after electrolytic treatment, can withstand salt spray resistance for more than 72 hours. The weld joints can withstand an 88-pound tensile test, with a protection rating of 1P20, and various specifications are available.
