Surface Treatment of HDGI Steel Coil:
Surface TreatmentFeatures
Chemical passivating treatmentminimize the chance of white rust forming during transit and storage
Maintain the bright, shiny appearance for a longer time
Oilsminimize the tendency for storage and transit stain
Passivating oilsprovide the protection from storage and transit stain by special chemicals called corrosion inhibitors

Zero spangleExtremely minimized spanglesSpecial painting application
Applications of HDGI Steel Coil:
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 HDGI Steel Coil:
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.
