Customized Galvanized Steel in Gi Coils / Density of PPGI is pre-painted galvanized iron coil, also known as pre-coated steel, coil coated steel, color coated steel etc., typically with a hot dip zinc coated steel substrate. For pre-painted galvanized iron coils, the thin steel plate is immersed in the molten zinc bath to make the surface of the zinc thin steel plate adhered.
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
