Technical QA/QC Verification
• EN 10204 3.1 Material Test Certificates (MTC) & Heat Traceability: All commercial dispatches are released alongside authentic, fully traceable MTC records documenting complete chemical melt data (including fine grain controls), yield strength points, impact toughness values, and macro-etch profiles. Fully structured to support third-party site validation from SGS, Bureau Veritas, or Intertek.
• Sovereign Capital Security Framework: To insulate international engineering contractors and global procurement firms from unexpected cross-border risk and timeline exposure, we authorize all high-volume productions under 100% Irrevocable Letters of Credit (L/C) at sight financial protocols.
Internal Protection & Ocean Logistics
• Rigid Iron Cradle Palletization & Timber-Choked Bracing: Finished bundles are nested securely inside heavy iron alignment chassis frames or robust solid wooden end-boxes to eliminate linear bending during crane loading. The entire lot is heavily braced with continuous steel tension straps and interlocked timber chocks within shipping containers to handle rough ocean transit.
• Complimentary 14-21 Days Extended Destination Port Demurrage Buffer: SXY Steel Group pre-embeds up to 21 days of extended free container demurrage into your ocean Bill of Lading, protecting your custom clearing brokers from unexpected port-side terminal processing penalties.
Ordinary low alloy steel is a kind of ordinary alloy steel containing a small amount of alloy elements (in most cases, the total amount of w does not exceed 3%). This kind of steel has high strength, good comprehensive properties, corrosion resistance, wear resistance, low temperature resistance, and good cutting and welding properties.
Under the condition of saving a lot of rare alloy elements (such as nickel and chromium), usually 1 t ordinary low alloy steel can be used for 1.2-1.3 t carbon steel, and its service life and scope of use are much longer than carbon steel. Ordinary low alloy steel can be smelted in open hearth furnace and converter with general smelting method, and the cost is close to that of carbon steel.

Round steel belongs to carbon structural steel for construction and machinery, while square steel belongs to carbon structural
steel for machinery. Both of them are simple section steel, and their section shapes are respectively round and square. Low carbon is mainly used for
drawing wire, forging rivets, bolts, nuts and other metal products of raw materials. Medium carbon round steel and square steel
are generally used to make mechanical structural parts.
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.
