ERW Steel Pipe
ERW (Electric Resistance Welded) steel pipes engineered for high-pressure fluid transmission, industrial structural fabrication, piling projects, and low-pressure gas pipelines. We guarantee premium hot-rolled coil raw materials, advanced inline high-frequency induction welding, completely localized heat-treated weld seams, and meticulous dimensional tolerance controls under our direct [2-Hour Rapid Quote] mill program.
Tired of slow factory responses while your project bidding deadline closes in? Terrified of catastrophic seam splits, wall-thickness variations, or failing strict site inspection parameters? Eliminate construction risks and secure your mill-verified ultrasonic testing logs immediately.

Technical QA/QC Verification
• Comprehensive Traceable Mill Test Certificates: Deliveries are strictly accompanied by complete EN 10204 3.1 Mill Test Certificates (MTC) detailing precise ladle chemical execution, tensile properties, yield strengths, flattening test validation, and impact logs. Fully optimized for independent visual audits by SGS, BV, or Intertek.
• Capital Security Guarantee: We eliminate cross-border financial friction completely by accepting long-term pipeline supply and infrastructure framework contracts secured via 100% Irrevocable Letters of Credit (L/C) at sight mechanisms.
Anti-Rust Packaging & Ocean Logistics
• Fortified Maritime Hexagonal Palletizing: Pipes up to 8 inches are bound into tight hexagonal bundles using high-tensile steel banding, fitted with nylon lifting slings, and separated via timber dunnage. Large-diameter pipes are securely blocked inside breakbulk vessel holds or containers using steel wire lashing frames.
• Extended Destination Port Demurrage: SXY Steel Group coordinates 14 to 21 days of complimentary container and breakbulk demurrage direct at your discharge terminal to provide ample clearing windows for your destination customs brokers and regional land hauling teams.

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.
