Technical QA/QC Verification
• 100% Verifiable Mill Certificates: Every batch is accompanied by comprehensive EN 10204 3.1 Mill Test Certificates (MTC) documenting explicit heat chemistry numbers, verified core loss logs, and coating insulation thickness performance. Fully prepared for inspection by SGS, Bureau Veritas, or Intertek.
• Financial Security Guarantee: We eliminate cross-border transaction risk completely by processing high-volume manufacturing export supply agreements through 100% Irrevocable Letters of Credit (L/C) at sight.
Anti-Rust Packaging & Ocean Logistics
• Industrial Seaworthy Radial Packaging: Products are enclosed within heavy-gauge outer steel covers, utilizing hard-tempered internal and external metal corner shrouds, high-load tension strapping, and fortified timber export pallet configurations.
• Extended Port Demurrage Allocations: SXY Steel Group secures 14 to 21 days of complimentary container demurrage at your destination terminal to shield local logistics workflows and customs clearance steps from storage surcharges.

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.
