GI sheets means galvanizing iron sheets. Galvanizing is a process by which iron is made rust free. In galvanizing process the zinc coating is done on the iron or steel to make it rust free. So, GI sheets are stainless steel sheets galvanized with zinc. GI sheets also include hot dip and electro galvanized steel sheets. Besides protecting the steel from rust and corrosion, the zinc also keeps the initial strength of the steel intact for long time. The other minor function of the zinc is to give polished finish to the sheets.
GI sheets find uses in every sector of the economy. They are used in agriculture as grain silos, feeding troughs, sprayers and pans. In construction activities, GI sheets find wide use as roof sheets, walls, panels, covers, rolling shutters, highway bombers, partition walls, and painted coated products.
