Detailed Solution

The given statement is true.
Concept- Galvanization is primarily done to stop iron and steel from rusting. Melted zinc is drip-coated onto the steel or iron surface in this procedure. The long lifespan of the item is due to the slow corrosion of zinc. An item would require less maintenance after galvanising, which would result in lower maintenance costs in the mechanical industrial sector.
Corrosive chemicals are prevented from accessing the underlying steel or iron by the zinc's formation of a barrier.
As a result, zinc acts as a sacrificial anode; the remaining zinc will continue to scratch the exposed steel.
Therefore, by corroding before them, the zinc defends its base metal.
Any galvanised material's outer layer of zinc forms zinc oxide when it combines with ambient oxygen (

).
Hence, the given statement is true.
