REGAN B.I & G.I 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.
