What is the advantage of galvanized iron over tin-plated iron?
Answers
Answer:
to prevent rusting
Explanation:
Galvanization protects iron from rusting.Iron corrodes and form a layer of zincoxide on iron surface and thus stops air and water reaching the surface of iron

Answer:
Galvanizing protects the underlying iron or steel in the following main ways:
The zinc coating, when intact, prevents corrosive substances from reaching the underlying steel or iron.
The zinc protects iron by corroding first. For better results, application of chromates over zinc is also seen as an industrial trend.[citation needed]
In the event the underlying metal becomes exposed, protection can continue as long as there is zinc close enough to be electrically coupled. After all of the zinc in the immediate area is consumed, localized corrosion of the base metal can occur
