- Abstract
Galvanised roofing sheet is widely used in the construction and building industry. However, the challenge caused by corrosion under service failure has led to this present work. This study presents the experimental investigation and simulated prediction of the selective material in 3.5 % NaCl condition. The corrosion resistance properties were examined using the potentiodynamic polarization technique and COMSOL. The mathematical modeling and simulation analyzed when done with model geometry in a single electrolyte domain and predicted for 1, 6 and 12 months for a sample labeled A-E. The results show that sample C provide lower corrosion deformation among all sample under investigation with Rp of 234.24 O, and CR of 0.51052 mm/y and corr value of -1.2837 (V) compare to sample A with higher corrosion rate of 2.9085 mm/yr and corr of -1.489 (V).
