Studying Corrosion Resistance of Different Roofing Sheets in Ghana

Background: The request for housing in Ghana is great and as a result the selection of durable roofing sheets have become very significant as roofing plays a vital role in building construction. The goal of the investigation was to see how corrosive compounds affected the most predominant roofing sheets on the Ghanaian market. One-star galvanized Japan [G1*Jap], Galvanized Coated [GC], Aluzinc three star galvanized [AlZn3*], One Star Galvanized Indi [G1*Ind], and Aluminium [Al] were the most common on the market and were therefore used. The corrosion experiments were carried out by putting the various samples in five jars containing various chemicals for varying amounts of time. A computer interfaced Optical Microscope (Leica DM 2500M) was employed to study the surface microstructures of the corroded surfaces, with the corrosion rates per day being determined.
Results: Average corrosion rates for One-star Galvanized Japan [G1*Jap] roofing sheets were observed to be the most corrosive resistant whiles [AlZn3*] roofing sheets were the least resistant to corrosion. Generally, G1*Jap roofing sheet stood out as the best roofing sheet in terms of resistance to corrosion.
Conclusion: These numbers lead to the conclusion that when compared to the other roofing sheets, G1*Jap roofing sheets were shown to be the most corrosion resistant. The most corroded roofing sheets were found to be Aluzinc three star galvanized [AlZn3*] roofing sheets.
