 abstract={In the present study corrosion behaviour of three coated steel sheets in different corrosive environments was evaluated using various characterisation techniques. Multiple types of corrosion tests, like salt spray test, 100% relative humidity test and chemical resistance test, were performed to report the corrosion resistance of samples in different corrosive environments. Enhanced corrosion resistance properties of the colour-coated samples were obtained from all the studies, followed by galvalume and galvanised samples. Cyclic voltammetry reveals a slightly higher pitting for the galvalume sample. SEM, EDS, XRD and Raman analyses for the salt spray tested and 100% humidity tested galvanised samples shows various corrosion products with their morphologies. XRD analysis reveals Zn5(OH)8Cl2H2O (simonkolleite), ZnO (zinc oxide), β-Zn (OH)2, Zn (OH)2 (zinc hydroxide) and Zn (ClO4)2 for salt spray tested samples whereas for the 100% relative humidity tested samples, main corrosion products are ZnO (zinc oxide), β-Zn (OH)2, Zn (OH)2 (zinc hydroxide), Fe and Zn. Raman spectroscopy reveals the presence of ZnO, β-FeOOH, white rust, green rust, FeCl2, Fe3O4, FeOH, Fe2O3 and δ-FeOH for salt spray tested samples, but for 100% humidity test, only ZnO is revealed.},
