Process of Galvanized steel coil

Pay off reel → double cut shear → welder-notcher → entry accumulator → pre cleaning section → furnace → hot bridle → zinc pot → air knife → after cooler → water quench → dryer → skin pass mill → dryer → tension leveler → dryer → chemical coater → chemical oven → cooler → exit accumulator → oiler → exit shear → tension reel.

Surface Treatment of Hot Dip Galvanized Steel Coil

Surface Treatment	Features
Chemical passivating treatment	minimize the chance of white rust froming during transit and strorage; maintain the bright, shiny appearance for a longer time
Oils	minimize the tendency for storage and transit stain
Passivating oils	provide the protection from storage and transit stain by special chemcials called corrosion inhibitors

Surface Finish of Hot Dip Galvanized Steel Coil

Surface finish	Pattern	Application
Regular spangle	Standard spanlges with flower pattern	General uses
Minimized spangle	Minimized spangles than regular	General painting application
Zero spangle	Extremely minimized spangles	Special painting application
