Manufacturing Process
Produced via advanced Electric Resistance Welding (ERW) technology, the pipes are cold-formed from high-quality hot-rolled or cold-rolled steel coils. The high-frequency welding process ensures a uniform, defect-free longitudinal seam with excellent metallurgical bonding. The resulting sections exhibit superior mechanical properties, consistent yield strength, outstanding weldability, and reliable low-temperature toughness
Quality Assurance & Compliance
Every batch EN10219 CHS RHS SHS ERW Steel Pipe undergoes rigorous inspection protocols, including
Ultrasonic testing (UT)
Hydrostatic pressure test
Chemical compositon test
Mechanical property verification (tensile, flattening and bend tests).
Full traceability is maintained through mill test certificates (MTC) per EN 10204 3.1 form.
The product line supports seamless integration with international design codes, ensuring compliance with global procurement and construction safety regulations
Applications
EN10219 CHS RHS SHS ERW Steel Pipes are extensively utilized in:
• Structural steel frameworks, bridges, and high-rise buildings
• Machinery manufacturing, automotive chassis, and agricultural equipment
• Guardrails, scaffolding, shelving systems, and industrial racks
• Architectural decoration, glass curtain wall supports, and door/window frames
• Fluid transport, boiler systems, and heat exchange units
Surface Treatment & Packaging
To enhance longevity and meet project-specific environmental requirements, EN10219 CHS RHS SHS can be supplied with various surface treatments, including black painting, anti-rust oil application, hot-dip galvanizing, bitumen coating, or Fusion Bonded Epoxy (FBE). Products are securely packed using standard seaworthy packaging or customized solutions to ensure safe global transportation and prevent handling damage.
