☀️ Solar Boom Drives Galvalume Demand – Why GL Steel Is the Backbone of Photovoltaic Mounting Systems

The global solar boom is reshaping the coated steel market. According to industry data, a 1MW photovoltaic project requires 30–35 tons of coated steel for mounting structures, while a 1GW project requires 30,000–35,000 tons. As solar installations accelerate worldwide, demand for high-corrosion-resistance steel is surging – and galvalume (GL) steel is at the center of it.

✅ Superior corrosion resistance – The 55% aluminum-zinc alloy coating delivers 2–6 times the corrosion resistance of traditional galvanized steel in coastal and industrial environments

✅ Excellent heat reflectivity – GL steel reflects heat at twice the rate of GI, reducing panel temperatures and improving solar efficiency

✅ Long service life – With AZ150 coating, GL steel can withstand 25+ years of outdoor exposure without significant degradation

✅ Cost-effective – Compared to stainless steel or aluminum, GL offers an optimal balance of performance and cost

✅ Coating weight: AZ30 to AZ275 – China‘s first producer to reach AZ275, while others are limited to AZ150

✅ Thickness: 0.12mm to 3.0mm

✅ Width: 900mm to 1600mm

✅ Grades: DX51D–DX57D, S220GD–S550GD

✅ Daily stock: 5,000+ tons – fast delivery guaranteed

✅ Surface treatment: Anti-fingerprint film available in golden, green, blue, and other colors

With global tariffs rising and supply chains tightening, galvalume prices are under upward pressure. CNB Group has 5,000+ tons of GL in stock, ready to ship.
