Detailed Solution

A zinc coating is applied to the iron, which protects it from rust and corrosion.
Galvanizing is the process of plating steel or iron with a protective zinc coating to prevent corrosion. The most popular procedure is hot-dip galvanizing, which consists in immersing the pieces in a bath of molten zinc. Galvanizing protects in two ways: it creates a corrosion-resistant zinc coating that prevents corrosive elements from accessing the more fragile parts of the metal, and it protects the metal itself.
Because the zinc acts as a sacrificial anode, even if the coating is damaged, the exposed steel is protected by the remaining zinc.
As a result, a zinc coating is applied to the iron, which protects it from corrosion and rust formation.
