Corrugated galvanized iron or steel is a building material composed of sheets of hot-dip galvanized mild steel, cold-rolled to produce a linear corrugated pattern in them. By galvanizing, protection of the steel structures against corrosion resistance is improved by numerous degrees of magnitude; the corrosion protection achieved by zinc-based coatings is as a result of the galvanic effect, because zinc is anodic to iron which make it acts a sacrificial metal in an aqueous or humid environment..
