Electro-galvanised steel sheet consists of a cold rolled steel substrate coated with zinc by electrolytic deposition on a continuous line. The electro-galvanising process permits the coating of either one or both sides of the sheet, and the coating of different thicknesses of zinc on the two sides of the sheet.

Electro-galvanised steel sheet is intended for applications involving all forming, drawing, stretching and bending processes during the manufacture of articles. A range of coating thicknesses is offered, with a corresponding increase in corrosion protection.
