CGI Sheets- Corrugated Galvanized iron is a building material made up of sheets of hot-dip galvanised mild steel that have been cold-rolled to create a ridged pattern. Because the steel must be stretched to bend perpendicular to the corrugations, the corrugations improve the sheet’s bending strength in the direction perpendicular to the corrugations, but not parallel to them.

CGI is lightweight and easily carried. It’s commonly used in industrial and construction industry.
