Chromium Free Galvanized Steel Coils 0.4mm-3.5mm Eco Friendly Coating ASTM A653M

​Chromium-Free Galvanized Steel Coils | 0.4-3.5mm | Eco-Friendly Coating | ASTM A653M

Chromium-Free Galvanized Steel Coils redefine sustainability and performance, combining ​ASTM A653M compliance with an ​eco-friendly, hexavalent chromium-free coating for industries prioritizing environmental safety. Available in ​0.4–3.5mm thicknesses and widths up to ​1,500mm, these coils deliver exceptional corrosion resistance (1,200+ hours salt spray) while meeting strict EU REACH and RoHS standards. Ideal for automotive, construction, and consumer goods, they offer a greener alternative without compromising durability or aesthetics.

Key Benefits:

• ​Toxic-Free Coating: Chromium-free passivation ensures worker safety and compliance with global environmental regulations.
• ​Superior Corrosion Resistance: Zinc coating (Z60–Z275) with 15–30+ years lifespan in coastal/industrial environments.
• ​ASTM A653M Compliance: Certified for SS Grades 33–80, ensuring structural integrity and weldability.
• ​Lightweight & Versatile: 0.4–3.5mm thicknesses for precision stamping, bending, or roll-forming.
• ​Sustainable Production: Zero wastewater discharge, 80% recycled steel content, and ISO 14001-certified manufacturing.
• ​Fast Customization: Pre-cut, embossed, or pre-painted options (RAL colors) for streamlined workflows.
