Engineered for harsh environments, our ASTM G90 Galvanized Steel Coil delivers extreme corrosion resistance with a robust 275g/m² zinc coating (equivalent to Z275 per ISO standards), forming a 38.5μm protective layer that withstands 1,000+ hours in salt spray tests (ASTM B117). The hot-dip galvanization process bonds zinc to a high-strength steel base (Grades: DX51D, SGCC, S350GD), ensuring decades of service in coastal, industrial, and high-humidity zones. Certified to ASTM A653, JIS G3302, and EN 10142, this coil is ideal for critical infrastructure demanding longevity with minimal maintenance.
