GI Sheet Roofing
GI Sheets are value added steel products which are tough, sturdy, light weight, bright, corrosion resistant and easy to transport. Galvanizing is carried out on cold rolled sheets/cold rolled strips. Galvanizing process is broadly divided into hot dipping and electro-galvanizing. The hot dip process is more suitable for heavy coating weights, and electro-galvanizing for lighter coatings. For reasons of efficiency, galvanizing of cold rolled strip is more common than galvanizing of cold rolled sheets. Galvanizing process is not dependent on weather conditions.
Galvanization is the process of applying a protective zinc coating to steel or iron in order to prevent it from rusting. The galvanized iron (GI) sheets for roofing are produced as plain coils / sheets (GP) and corrugated sheets. GI sheets are produced both in annealed and full hard conditions. GI sheets are virtually maintenance free and last longer. The life expectancy of GI sheets is quite high in rural, urban and coastal environments. The surface of GI sheet is aesthetically pleasing.
