Premium Corrugated Galvanized Steel Roofing Sheets

High-end wavy galvanized steel sheet specially designed for harsh environments uses Z275 or higher high-zinc layer base sheet (zinc layer ≥180g/㎡), and forms a dense zinc-iron alloy layer through advanced continuous hot-dip galvanizing process. The anti-corrosion life is 50% longer than that of ordinary galvanized sheet. The unique wave structure enhances wind pressure resistance (≥2.0kPa), and combined with the patented drainage trough design, it is the ultimate roof solution for modern factories, logistics warehouses, and agricultural facilities. Galvalume Steel: The creator of the anti-corrosion myth55% aluminium, 43.4% zinc and 1.6% silicon were refined through hot-dip galvanizing to produce nanoscale protective armor. It has stood firm in the coastal salt spray for 30 years without corrosion, and its corrosion resistance is three times that of ordinary galvanized steel! From cross-sea Bridges to chemical plants, it promises zero rust, reducing maintenance costs by 70% directly, a…
