Process of Hot Dip Galvanized Steel strip:
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 Strip:

(1)Chemical passivating treatment. (minimize the chance of white rust forming during transit and storage, maintain the bright, shiny appearance for a longer time )

(2)Oils. (minimize the tendency for storage and transit stain )

(3)Passivating oils. (provide the protection from storage and transit stain by special chemicals called corrosion inhibitors )

Surface Finish of Hot Dip Galvanized Steel Strip:
Regular Spangle, Mini Spangle, Big Spangle, Zero Spangle...



Applications of Hot Dip Galvanized Steel Strip:
1) cable armouring
2) deep drawing applications
3) constructions (roofing, external wall, handrail etc. )
4) electric appliance (refrigerator, washing machine, recorder, microwave, etc)


Features of Hot Dip Galvanized Steel Strip:
Galvanized steel strip and tape consists of Cold Rolled Steel Coil after it has undergone hot dip galvanization and slitting processes. Galvanized steel strip and tape with characteristics of superior anti-corrosion, high surface quality and good deep process, and a lifetime exceeds other cold rolled products by 15-20 years.
