Product Description

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.

Frequently Asked Questions
Q: Why choose G90 over standard coatings?
A: G90's 275g/m² coating provides 2X longer lifespan in coastal/industrial zones vs. G60 (180g/m²).
Q: Can it withstand welding?
A: Yes. Zinc-iron alloy coatings (ZF) offer superior weldability for structural joints.
Q: Maintenance requirements?
A: Self-passivating zinc layer reduces need for repainting; biennial inspections suffice.
Q: Certifications for EU projects?
A: Complies with EN 10142 (EU) and JIS G3302 (Japan).
Q: What is your working time?
A: In general, our online service time is Beijing time: 8:00-22:00, after 22:00, we will reply to your inquiry in the coming working day.
