Galvanized Steel Coils 0.2-4mm Thick ASTM A653/Z275 Coating Industrial Applications
Galvanized Steel Coils are precision-engineered for durability and versatility across demanding industrial environments. Manufactured under ASTM A653 and Z275 coating standards (275g/m² zinc layer), these coils combine high tensile strength (330–550 MPa) with superior anti-corrosion properties, ideal for construction, automotive, and agricultural sectors. With thickness options from 0.2mm to 4mm and customizable widths (600–1,500mm), they ensure optimal performance in extreme weather, chemical exposure, and heavy-load applications.
