Technical QA/QC Verification
• 100% Traceable Mill Certification: All structural shipments are systematically supplied with original EN 10204 3.1 Mill Test Certificates (MTC), mapping full heat numbers to raw material chemical composition, actual yield strength, ultimate tensile capacity, and Charpy V-notch impact testing data. Fully approved for international inspection verification via SGS, Bureau Veritas, or Intertek.
• Capital Security Guarantee: We clear cross-border transactional anxiety by securing large-volume global infrastructure structural supply runs through 100% Irrevocable Letters of Credit (L/C) at sight financial frameworks.
Structural Protection & Ocean Logistics
• Heavy-Duty Transit Bracing & Anti-Deformation Blocks: Bundles are systematically stowed inside maritime containers or bulk holds with heavy structural timber bracing, anti-sliding wedges, and high-tensile steel cross-lashing lines to eliminate tube-on-tube collisions, crushing forces, or cross-sectional ovality deformation across extreme sea lanes.
• Complimentary Extended Destination Port Demurrage: SXY Steel Group automatically allocates 14 to 21 days of extended free container demurrage at your destination port, giving your local logistical teams ample operational time to process import filings and handle inland haulage.
Description
Rectangular tubes are formed from coils and then ran through a series of dies. They are are welded from the inside to form their shape. Rectangular tubes are generally used for maintenance and structural purposes.
For mechanical and structural applications, rectangular hollow sections (RHS) are popular. This is because the flat surface makes it a more economical structural solution for joining and different types of manufacturing work. For soldering or joining, RHS requires minimal edge preparation. Because of the rectangular shape of this type of hollow section, parts only need to be cut straight when joining to other flat surfaces.

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.
