Galvanized Steel Sheet is defined as a carbon steel sheet coated with zinc on both sides. Galvanized Steel Coil Importer produce galvanized steel with two main processes: continuous hot dip galvanizing and electro-galvanizing.
A zinc coating is one of the most effective and economical methods of protecting bare steel from a corroding environment. The zinc not only serves as a barrier between the steel and the environment, but it will also sacrifice itself to protect the underlying steel sheet. Sacrificial or galvanic protection occurs when two dissimilar metals are in contact and coupled with water and oxygen. Zinc corrodes preferentially to the iron in steel. This protection prevents corrosion of the steel at areas not covered with zinc. Thus, the spread of corrosion from cut edges, drill holes, etc. is minimized.
