CGI sheet stands for Corrugated Galvanized Iron sheet. It is a type of roofing material commonly used in construction and industrial applications. CGI sheets are made from galvanized iron or steel that is corrugated to add strength and rigidity to the sheet.
The corrugation process involves forming ridges and valleys along the length of the sheet, which not only increases its strength but also provides a better surface for water drainage. This design helps prevent water from accumulating on the roof, reducing the risk of leaks.
CGI sheets are typically coated with a layer of zinc through a process called galvanization. The zinc coating helps protect the underlying iron or steel from corrosion, extending the lifespan of the sheet and making it suitable for outdoor applications.
These sheets are commonly used for roofing and siding purposes in residential, commercial, and industrial buildings. They are known for their durability, affordability, and ease of installation. CGI sheets are available in various thicknesses and lengths to suit different requirements.
