Galvanised Iron :
Galvanised Coil and Sheet Steel

Galvanized sheet or coil is defined as a carbon steel sheet coated with zinc on both sides. Continuous hot dipping, or electro-galvanizing are the two processes used to produce galvanized sheet and coil.

A zinc coating is one of the most effective and economical methods of protecting bare steel from a corroding environment. The zinc not only serves as a barrier between the steel and the environment, it will sacrifice itself to protect the underlying steel sheet.

Sacrificial, or galvanic protection occurs when two dissimilar metals are in contact and coupled with water and oxygen. Zinc corrodes preferentially to the iron in steel. This protection prevents corrosion of the steel at areas not covered with zinc. Thus, the spread of corrosion from cut edges, drill holes, etc is minimized.

Applications of galvanized steel coil Widely used for roofs, outer walls, ovens, explosive-proof steel, electrically controlled cabinets

Surface Finish:

Type Surface Finish
Regular Standard spangles with flower pattern, suited for general use
Zero More minimized spangles than regular, with a beautiful gloss, suited for general painting applications
Ultra Extremely minimized spangles suited for special painting applications
Alloy coated iron-zinc
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: -
Agriculture Grain Silos, Sprayers, Ghamellas, Pans, Feeding Troughs, etc.
