Answer 2

Galvanization and painting are effective ways to prevent rusting. Galvanization involves the dipping of iron rods in molten zinc.

Once galvanized, moisture and air is prevented from affecting the iron rod surface and this method prevents rusting from taking place.

Another method of preventing rusting involves the use of paint on the iron surface. The paint cuts the moisture and air from affecting the iron rod surface.
