Compliant with GB/T 700 (Q215), EN 10025 (S185), and ASTM A283 (Grade A/C), these coils offer balanced mechanical properties—Q215 (yield 215MPa, tensile 335-450MPa), S185 (low-carbon ductility), A283 (tensile 310-415MPa)—with excellent weldability, formability, and cost efficiency. Ideal for construction frames, machinery parts, storage tanks, and automotive components, they ensure dependable performance in moderate-load environments while supporting cold/hot rolling and surface treatments like galvanizing for enhanced durability.
