What is GI Corrugated Steel Sheets

Feb 23, 2021

Galvanized iron (GI) sheets are steel sheets which are basically coated with zinc and include a range of hot dip galvanized and electro-galvanized steel sheets. Zinc weathers at a very slow rate, so the coating generally has a long life. Zinc has a greater electro-negativity than iron and hence provides cathodic (or sacrificial) protection to the steel.


This results in the zinc corroding in preference to the steel if the coating is chipped or damaged to expose the base metal.


GI Corrugated Sheet is a construction material ideal for roofing needs. It is made with hot-dipped galvanized metal, cold rolled to produce a pattern that increases its bending and malleability strength.
