Galvanization defined as zinc coating protection by hot-dip or electroprocesses, clarifying classification and protective-treatment scope. Definition and scope of galvanization: technical and dictionary sources define galvanization as the application of a metallic coating, especially zinc, to iron or steel by hot dip or electrodeposition methods to protect against corrosion; protection depends on coating thickness and process, and customs nomenclature treats such surface treatments as methods to improve properties or prevent rusting without changing the goods' primary classification.
