Engineered for solar panel mounting structures, our AZ180 Galvalume steel sheet features a hot-dip coating of 55% aluminum, 43% zinc, and 2% silicon, combining superior barrier and sacrificial corrosion resistance. Its key advantage is exceptional heat resistance, enduring continuous temperatures up to 315°C—critical for high-radiation environments with significant thermal cycling. This durability ensures an exceptionally long service life of 50-60 years, far exceeding the 25-30 year lifespan of typical solar panels and providing a truly maintenance-free, cost-effective mounting platform.
