Technical QA/QC Verification
• Directional Magnetic Domain Validation: SXY Steel Group conducts computerized magnetic testing across the rolling direction to verify maximum permeability, precise excitation power criteria, and absolute anisotropy control for minimal stray flux losses.
• 100% Traceable Mill Certificates: Every delivery includes detailed EN 10204 3.1 Mill Test Certificates (MTC) presenting specific ladle chemistry data, actual core loss metrics under standard testing, and glass-film insulation capability. Fully ready for validation by SGS, Bureau Veritas, or Intertek.
• Financial Security Guarantee: We mitigate international procurement risk completely by managing major manufacturing supply contracts via 100% Irrevocable Letters of Credit (L/C) at sight.
Anti-Rust Packaging & Ocean Logistics
• Comprehensive Interlaminar Protection: Slit CRGO edges are shielded using specialized dry anti-corrosion VCI sheets paired with strategic moisture desiccants to prevent sea-air humidity from causing edge oxidation or coating degradation.
• Industrial Seaworthy Radial Boxing: Coils are wrapped within a protective structural system: waterproof VCI base layer, heavy-gauge corrugated outer steel encasements, reinforced internal and external steel corner profiles, and high-load metallic strapping attached firmly to robust timber pallets.
• Extended Free Port Demurrage: SXY Steel Group arranges 14 to 21 days of complimentary container demurrage at your destination terminal to secure your domestic haulage setup and local custom clearances.

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.
