What does it mean when a material is described as galvanized?

When a material is described as galvanized, it specifically refers to the process of applying a layer of zinc to the surface of steel or iron. This zinc coating serves as a protective barrier against corrosion and rusting, significantly extending the lifespan of the metal in various environmental conditions. The galvanization process typically involves hot-dip galvanizing or electro-galvanizing, where the material is either immersed in molten zinc or coated with a zinc solution.

This protective feature is especially important in applications such as wireways, raceways, and fittings, where exposure to moisture and environmental elements can lead to significant deterioration of materials. Therefore, the correct understanding of galvanization is that it involves the application of a zinc compound, effectively enhancing the durability and longevity of metal products used in construction and electrical applications.
