Galvanization is the process of applying a protective zinc coating to steel or iron in order to prevent it from rusting.Today the corrugation process is carried out using the process of roll forming. This modern process is highly automated to achieve high productivity and low labour costs. In the corrugation process sheets are pulled off huge rolls and through rolling dies that form the corrugation. After the sheets pass through the rollers it is automatically sheared off at a desired length. The standard shape of corrugated material is the round wavy style, but can be easily modified to a variety of shapes and sizes by simply changing the dies. G. C. Sheets are widely and most commanly used in India for Industrial Shades, domestics and commercial use.
