galvanisoida

Galvanisoida is a verb that describes the process of coating a metal, typically iron or steel, with a protective layer of zinc. This process is primarily done to prevent rust and corrosion. The most common method of galvanizing is hot-dip galvanizing, where the metal object is immersed in a bath of molten zinc. Other methods include electrogalvanizing, which uses an electric current to deposit zinc, and mechanical galvanizing, which uses tumbling and impact to apply the zinc coating.

The zinc coating acts as a sacrificial barrier. It corrodes preferentially, meaning it oxidizes before the underlying steel does. This protects the steel even if the coating is scratched or damaged. Galvanizing is widely used in various industries, including construction, automotive, and manufacturing, for applications such as roofing, fencing, pipes, and structural components. The lifespan of galvanized steel is significantly extended compared to uncoated steel, making it a cost-effective solution for protecting against environmental degradation. The appearance of galvanized surfaces can range from a dull gray to a shiny metallic finish, depending on the specific process and alloy used.
