| DIN 1623 St14 / Q235 | EN 10142 DX53D+Z | ASTM A653 DDS | JIS G3302 SGCD2 | Deep drawing execution quality. Engineered specifically for extreme multi-axis deformation, deep automotive stampings, and complex zero-fracture profiles. |
Technical QA/QC Verification
• 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.
Anti-Rust Packaging & Ocean Logistics
• 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 customs clearance margins.

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.
