This paper investigate the corrosion resistance properties of zinc galvanised roofing sheet selected from Nigeria manufacturing industries in an attempt to predict its durability, efficiency and corrosion properties in 0.5 M HCl. The electrochemical behaviour assessment was done using potentiodynamic polarization and COMSOL multiphyics prediction for 1, 6 and 12 month for all selected zinc galvanised steel under study. It was found that sample B provide higher corrosion resistance propagation of 151.81(Ω) with significant Ecorr value of -1.4057V thus, with corrosion rate of 2.452 mm/yrs. The least effective from produce zinc galvanised steel is sample E with 11.979(Ω)in the presence of 0.5 M HCl. A higher corrosion rate of 9.5462 mm/y was obtained for sample E as against 2.452 mm/y of sample B. This was further confirmed by the predictive simulation and modelling degradation analysis.
