• Third-Party Inspecting Supported: Full collaboration with independent assessment firms (SGS, Bureau Veritas, or Intertek) to verify exact dimensional thickness thresholds, coating adhesion tests, and tension-leveling straightness metrics at the loading bay.
• Capital Protection Framework: SXY Steel Group eliminates international trade risk completely by managing all bulk supply contracts under 100% Irrevocable Letter of Credit (L/C) at sight payment pathways.
• Rigid Perimeter Steel Banding: High-tensile structural steel straps secure the layout firmly to heavy wooden or metal skids, preventing edge-buckling and internal shifting during extreme rough-sea transit cycles.
• Extended Port Demurrage Safety: 14 to 21 days free demurrage terms pre-negotiated directly with shipping networks to insulate your delivery budget from regional customs clearing bottlenecks.

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.
