Angola's manufacturing sector, particularly in metal structure fabrication, faces severe challenges due to high humidity and salinity along the Atlantic coast. The reliance on traditional low carbon steels often leads to rapid oxidation, necessitating frequent and costly repainting cycles for bridges and industrial warehouses.
In the interior regions, temperature fluctuations and seasonal rains demand materials that can withstand atmospheric corrosion without compromising structural load-bearing capacity. There is a growing shift toward mild low alloy steel to enhance durability while maintaining weldability for local contractors.
Currently, the market is transitioning from basic steel import reliance to seeking specialized materials like cor ten steel plate, which forms a protective patina, eliminating the need for surface coatings in harsh Angolan environments.
