The essential component for rusting is the contact of metal with oxygen and moisture. When the iron gate is painted, it protects the iron to get in contact with oxygen, hence prevents it from rusting.

For rusting, the presence of air(oxygen) and moisture(water) is required. In coastal areas the quantity of moisture present in air is higher than in the deserts. Hence, rusting of iron objects is faster in coastal areas than in deserts.
