What is GI coil?
Galvanized Steel Coils / Sheets (GI) JS METALS is a leading supplier of galvanized steel sheet & 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.
What is galvanized steel coil?
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.
