GI Corrugated Roofing Sheet is protected from corrosion by a zinc coating applied to the steel sheet.The zinc coating should be thick enough to ensure the durability of the GI Corrugated Roofing Sheet by preventing corrosion. A 20 µm coat of zinc should be applied per side of the GI Corrugated Roofing Sheet (total of 40µm for both sides of the GI Corrugated Roofing Sheet equivalent to 275g/m²). Zinc coating thickness and method of galvanization are the most important factors for durability.
The galvanization method used must be hot-dip galvanization as it better ensures the durability of the GI Corrugated Roofing Sheet. Other methods such as electro-galvanization should be avoided because the coating thickness is thinner than hot-dip galvanization and the durability of the GI Corrugated Roofing Sheet will be reduced, as a result. It's possible to increase the zinc coating thickness in order to increase the service life (durability) of the GI Corrugated Roofing Sheet.
