What is CGI Sheets: Sizing and Specifications about?

Corrugated galvanized iron (CGI) sheets are used for roofing. Minimum recommended thicknesses are 0.551mm for permanent shelters or those in snowy areas, 0.475mm for shelters in low wind areas, and 0.4mm for shelters in very low wind areas. Zinc coating of at least 40 microns protects the steel from corrosion. Proper installation using roofing nails can ensure strength against wind loads. Quantities for projects should include overlaps between sheets and extra materials for losses.
