Technical QA/QC Verification
• 100% Verifiable Mill Test Certificates: Every batch is accompanied by comprehensive EN 10204 3.1 Mill Test Certificates (MTC) detailing complete chemical ladle analysis, actual magnetic core loss curves, and insulation coating quality. Third-party visual and performance validation by SGS, Bureau Veritas, or Intertek is fully integrated.
• Capital Security Guarantee: We eliminate cross-border capital vulnerabilities by backing large-scale industrial transactions with 100% Irrevocable Letters of Credit (L/C) at sight.
Anti-Rust Packaging & Ocean Logistics
• Heavy-Duty Seaworthy Structural Wrap: Coils are enclosed via heavy-duty industrial shielding: inner waterproof VCI protection, outer structural corrugated steel jackets, reinforced steel edge guards, and high-strength metal banding fixed securely to robust export pallets.
• Extended Demurrage Allocation: SXY Steel Group coordinates 14 to 21 days of free container demurrage at your arrival port to safeguard your domestic freight and customs clearance timeline.

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.
