Technical QA/QC Verification
• EN 10204 3.1 Material Test Certificates (MTC) & Salt Spray Simulation: All commercial orders are accompanied by verified original MTC tracking sheets, itemizing comprehensive heat codes, tensile strength profiles, exact elongation values, and documented salt spray corrosion resistance logs. Fully aligned to accommodate independent third-party inspection audits from SGS, Bureau Veritas, or Intertek.
• Sovereign Capital Security Framework: To insulate commercial engineering contractors and procurement firms from international currency changes and delivery scheduling anxieties, we execute all high-volume productions under 100% Irrevocable Letters of Credit (L/C) at sight financial protocols.
Internal Protection & Ocean Logistics
• Rigid Iron Cradle Palletization & Cross-Timber Bracing: Finished bars are arranged inside heavy iron support frame chassis or solid wooden end-boxes to completely eliminate linear bending or shifting during crane terminal processing. The container lot is heavily cross-braced with continuous steel tension straps and interlocked timber chocks.
• Complimentary 14-21 Days Extended Destination Port Demurrage Buffer: SXY Steel Group proactively secures pre-cleared, extended 14 to 21 days of container free-time demurrage parameters on your ocean Bill of Lading, giving your customs agent an open window to handle processing without incurring costly storage fines.
Galvanized round steel is a geometric object made of iron or materials with certain strength and toughness by rolling, extruding, casting, hot galvanizing anti-corrosion profile surface and other processes. Hot dip galvanized round steel is produced by advanced galvanizing process, and its surface is glossy and durable. Galvanized round steel products have been used in many fields. The advantage of hot-dip galvanized round steel is that it has a long anti-corrosion life and has been a popular anti-corrosion treatment method to adapt to a wide range of environments. It is widely used in electric power tower, communication tower, railway, highway protection, street light pole, marine components, building steel structure components, substation ancillary facilities, light industry, etc.

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.
