Question

Why is an iron grill painted frequently?

Answer 1

To prevent rusting of iron substances, they are painted frequently. Iron is a reactive metal that starts corroding in the presence of air (oxygen) and water (moisture). Iron reacts with oxygen in moist air, forming a brown, flaky layer of iron oxide (rust) on its surface. This is called rusting. This rust causes significant damage to iron objects by weakening them. Therefore, an iron grill is painted frequently to prevent corrosion.
