Q1: Coating thickness in case of galvanising of steel sheet generally corresponds to the deposition of __________ gms of zinc per m² of steel strip.

ANS:C - 120-500

In the case of galvanizing of steel sheet, the coating thickness generally corresponds to the deposition of 120-500 grams of zinc per square meter of steel strip. Galvanizing is a process where steel is coated with a layer of zinc to protect it from corrosion. The thickness of the zinc coating is typically measured in terms of weight per unit area, commonly expressed in grams per square meter (g/m2). The range provided, 120-500 grams per square meter, represents the typical thicknesses of zinc coatings applied during the galvanizing process for steel sheet.
