| GB/T 700 Q355 | EN 10346 S355GD+Z | ASTM A653 SS Grade 50 Class 1 | JIS G3302 SGC440 | Yield Strength ≥ 355 MPa. High-tensile, structural low-alloy engineering matrix designed for severe structural load calculations and zero-failure environments. |
• 100% Traceable Mill Certificates: All shipments include rigorous EN 10204 3.1 Mill Test Certificates (MTC) detailing absolute ladle chemistry analysis, clear yield-to-tensile boundaries, and zinc adhesion validation. Fully open to independent auditing by SGS, Bureau Veritas, or Intertek.
• Financial Liquidity Protection: We fully eliminate cross-border transaction capital risks by supporting high-tonnage industrial steel contracts under 100% Irrevocable Letters of Credit (L/C) at sight.
• Seaworthy Heavy-Duty Wrapping: Coils are secured utilizing an industrial multi-layer barrier: inner waterproof VCI anti-corrosion wrap, robust outer corrugated steel protective jackets, heavy-gauge interior/exterior steel edge guards, and high-tensile strapping anchored tightly to sturdy wooden pallets.
• Extended Port Storage cushion: SXY Steel Group pre-allocates 14 to 21 days of complimentary container demurrage at your destination port to ensure ample local custom clearance margins.

Packing and shipping
Our company has passed ISO9001 quality management system certification, Our Mill product with CE/EN10204 / ASTM/Classification society certificate/CASO/BIS etc certificate.All the customers give good appreciation to our products.We are glad to be your good partner.
Application Areas
Steel is widely used in steel structure workshops, bridge frames, main structures of high-rise buildings, and infrastructure construction (such as highways, oil and gas pipelines). Its high strength properties ensure load-bearing stability and seismic performance. In ship manufacturing, steel is used to build hull structures, decks, and internal components. Hot-rolled coils rely on their load-bearing capacity to adapt to harsh environments.
Factory workshop
With a commitment to excellence, innovation, and sustainability, the company has established itself as a trusted partner in the international steel industry.After nearly two decades of relentless endeavour, our client base now spans over 110 countries and regions across Europe, the Middle East, South America, and Southeast Asia.
