INTRODUCTION: GALVANIZED STEEL IRON COIL AND SHEET
Galvanized sheet or coil is a process by which zinc, a non-corrosive metal, is coated over corrosive metals, such as iron and steel. Because zinc is more reactive than iron or steel, the zinc galvanized coating corrodes first, protecting the steel or iron substratum. When exposed to the atmosphere, zinc reacts with oxygen to form zinc oxide. This further reacts with carbon dioxide to form zinc carbonate, a fairly strong material that stops further corrosion by protecting the steel or iron from the elements.
Galvanized steel is widely used in applications where rust resistance is needed, such as roofing and walling, handrails, consumer appliances and automotive body parts.

More minimized spangles than regular, with a beautiful gloss, suited for general painting applications
Extremely minimized spangles suited for special painting applications
Standard spangles with flower pattern, suited for general use
Galvannealed steel sheet has a highly workable iron-zinc alloy layer. Good paint-adherence properties, corrosion resistance and weldability make them ideal for use in home electrical appliances and buildings
Galvanized Sheets are used extensively in various applications. Some of the common uses are:
