Why do we apply Paint on Iron articles?

Paint is applied on iron articles to shield them from corrosion caused by environmental elements like moisture and oxygen. Corrosion leads to rust formation, tarnishing iron surfaces and compromising their integrity. By forming a protective barrier, paint inhibits rusting, extending the lifespan of iron structures, reducing repair costs, preserving aesthetics, and maintaining structural soundness.
