Anodes (Wholesale) is a subdivision of the Metals Service Centers and Offices (Wholesale) industry that specializes in the distribution of anodes, which are electrochemical devices that are used to protect metal structures from corrosion. Anodes are made from a variety of materials, including zinc, aluminum, magnesium, and other alloys. The primary function of anodes is to corrode in place of the metal they are protecting, thereby extending the life of the metal structure. Anodes (Wholesale) companies typically purchase anodes from manufacturers and distribute them to a range of customers, including construction companies, shipyards, and industrial facilities.
