Galvanized Metal pipe because the floor coating by galvanized is extensively applied for a lot of industries such as structure and constructing, mechanics (in the meantime together with agricultural equipment, petroleum machinery, prospecting machinery), chemical industry, electrical power, coal mining, railway autos, car business, freeway and bridge, sports facilities and so forth. Corrosion may also happen when the coating is penetrated, as when somebody drives a nail via a sheet of galvanized iron, exposing the iron inside to the elements.
