What is the process called in which iron or steel is coated with a layer of zinc to help prevent rusting?

Explanation

Galvanization is the process of coating iron or steel with a protective layer of zinc, which helps prevent rusting both by physically shielding the underlying metal from moisture and oxygen and by acting as a sacrificial layer that corrodes preferentially if the coating is scratched. This process significantly extends the useful lifespan of iron and steel products exposed to outdoor conditions, such as fencing, roofing sheets, and pipes. Galvanized metal typically has a distinctive dull, spangled surface appearance compared to plain steel. Explore more Everyday Science MCQs on mcqstutor to keep practicing.
