Hot Dipped Galvanized Steel Coils With Zero Spangle
Introduction of Zinc Coating Galvanized Steel Coils
For galvanized steel coils, the thin steel sheet is immersed in the molten zinc tank so that a thin sheet with a zinc layer adheres to the surface. Therefore, it is mainly produced by the continuous galvanizing process; the coiled steel sheet is continuously immersed in a galvanized bath with molten zinc to make it an alloyed galvanized steel sheet.
Application of Hot Dipped Galvanized/Galvanneal Steel Coils
Galvanized steel coils(GI steel coils) can be used for widely as follows,
(1)In the construction industry: to manufacture exterior and Interior products such as metal shingles, corrugated sheeting, sandwich panels, profiles, metallic ceilings, skirting boards, decorative panels inside heated and non- heated rooms, elevators, doors window shutters, shelves etc.
(2)In the automotive industry: to manufacture external and internal car body parts (car doors, car boots, oil filters, dashboards, windscreen wipers etc.
(3)In manufacture of home appliances, furniture, and consumer goods: metallic furniture, lighting equipment, shelves, radiators, сar doors, car boots etc.
