What is Galvanized metal roofing? 

Traditionally, galvanized metal roofs are made of a type of wavy carbon steel with a coating of galvanized metal. This galvanized coating is given by dipping in a molten solution of hot zinc.

The positive ions of zinc form a bond with the iron in steel which forms a glossy anti-rust surface. This whole process is called galvanization in the metal roof.

After this process is done, it has to be cooled to harden again. After this, the corrugation process increases the strength and stability of the roof.
