What are galvanized coils?
Hot dipped galvanized steel sheet & coil is made of carbon steel coated in zinc utilizing the hot-dip process. The end
result of this process is a layer of zinc on each side of the steel sheet or coil that is tightly adhered to the steel through
the formation of an iron-zinc alloy bonding layer.
Why zinc is coated on steel?
Zinc coatings are predominantly used to improve the aqueous corrosion of steel by two methods, barrier protection and
galvanic protection. In barrier protection, the zinc coating, which separates the steel from the corrosion environment, will
first corrode before the corrosive environment reaches the steel.
What is zinc coated steel sheet?
The steel sheet is covered with a uniform zinc-plated layer by controlling the amount of zinc coating. The zinc-plated layer
itself is chemically treated, which ensures excellent corrosion resistance. Outstanding appearance and workability.
