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 painti
