Its core advantages include: Extraordinary corrosion resistance: Aluminum forms a dense oxidation barrier to isolate moisture, while zinc provides “sacrificial protection”, especially in salt spray and industrial environments, with a lifespan 3-6 times longer than galvanized steel. High temperature stability: Aluminum composition endows excellent heat resistance (reflecting 80% of heat), significantly reducing the internal temperature of buildings. […]
