Hot-dip galvanzed steel coil

Galvanized steel is defined as a carbon steel sheet coated with zinc on both sides. There are two main processes used to produce galvanized steel: continuous hot dipping and electro-galvanizing.  

The hot dipping process consists of passing the steel through a bath of molten zinc, while the electro-galvanizing process consists of the application of zinc through 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, 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.Galvanized Steel Sheet & Coil Material Types

Excellent anti-corrosion, paintability, and processability due to the self-sacrificing characterisiticof zinc.

Available to select and produce the desired amount of zinc gilded and in particula enables thick zinc layers(maximum 120g/m2).

Classified as either zero spangle or extra smooth depending on wheteher the sheet undergoes skin pass treatment.
