Some metals, including iron, have oxides that do not hold together well, so they fall off, exposing the surface to air, or allow oxygen to pass through them, so pits can form. Zinc is not one of these; when it oxidizes, the oxide adheres to the surface of the metal, covering it and protecting it from atmospheric oxygen. If the zinc is plated onto iron, it protects the iron.
One element that can protect iron from rusting and has good electrical conductivity is zinc. Zinc can be used as a sacrificial coating on iron surfaces through a process called galvanization, where the zinc layer corrodes instead of the iron. This protects the iron from rusting while providing good electrical conductivity.
Stainless steel, which contains chromium, nickel, and other elements, is commonly used to prevent the rusting of iron. The chromium in stainless steel forms a protective oxide layer on the surface of the metal that helps to prevent corrosion.
Galvanising is the act of coating a metal (iron or steel) in a thin layer of zinc. The metal is dipped in molten zinc.
Zinc atoms are commonly used to protect iron from rusting through a process called galvanization. When zinc atoms are attached to the surface of iron, they act as a sacrificial anode, corroding first instead of the iron, thus preventing rust formation.
The Fe-Zn pair, often used in galvanization to protect iron from rusting, typically does not rust in the same way as pure iron. However, if rust does occur, the oxidation of iron leads to the formation of reddish-brown iron oxide (rust). The zinc, when intact, usually appears as a silvery-gray color. If the zinc layer is compromised, the presence of rust can give the affected area a combination of gray and reddish-brown hues.
to prevent rusting of the iron
Yes, zinc can prevent rusting of iron by acting as a sacrificial anode. When zinc is in direct contact with iron, it corrodes instead of the iron, forming a protective barrier that shields the iron from rust.

Zinc doesn't rust; zinc protect iron (and alloys) from rusting.
Yes, the zinc layer helps to preserve the iron sheet from rusting.
Try covering it in Zinc
Coating iron with zinc through galvanization creates a protective layer that acts as a barrier against corrosion. The zinc layer sacrifices itself to protect the underlying iron, as zinc corrodes preferentially over iron. This process helps prevent rusting and extends the lifespan of the iron material.
This metal is zinc (Zn).
