Production Facility of gi metal sheet

Process of gi metal sheet

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 gi metal sheet

Surface Treatment


Chemical passivating treatment

minimize the chance of white rust froming during transit and strorage

maintain the bright, shiny appearance for a longer time


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 gi metal sheet

Surface finish



Regular spangle

Standard spangles with flower pattern

General uses

Minimized spangles than regular

General painting applications

Zero spangle

Extremely minimized spangles

Special painting applications


Applications of gi metal sheet
1. Construction and building: roofings, ventilating duct; handrail; partition panel,etc.
2.Further processing: coating base plate.
3. Electric appliances: refrigerator; washing machine; recorder; microwave, etc.
