Definition

Noun: - Iron coated with zinc: Galvanized iron is iron or steel that has been coated with a layer of zinc to protect it from corrosion (rust).

Usage

Galvanized iron is used for its durability and rust resistance in construction and manufacturing. - It is commonly used for roofing, fencing, pipes, and buckets. - The zinc coating acts as a sacrificial anode, corroding before the iron does.
