Household  Prepainted Galvanized Steel Coil Industrial Construction





Galvanized sheet or coil is defined as a carbon steel sheet coated with zinc on both sides. Continuous hot 

dipping, or electro-galvanizing are the two processes used to produce galvanized sheet and coil. Generally speaking, the hot 

dip process consists of passing the steel through a bath of molten zinc. The electro-galvanizing process consists of the application of zinc by electrolytic disposition. The result is a layer of 

zinc tightly adhering to the base metal through an iron-zinc bonding layer.

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, it will 

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.

Our Hot-dipped Galvanized products, as well as our Galvannealed (zinc-iron alloy coated) products are 

manufactured to ASTM A-653 specifications. Our Electrogalvanized products conform to ASTM A-879.
