EN 10219 S355J2H ERW Steel Pipe Structural Construction

Huayang EN10219 S355J2H ERW steel pipes are manufactured using advanced high-frequency electric resistance welding technology, ensuring precise dimensional tolerances, uniform wall thickness, and consistent weld quality. EN10219 S355J2H is a cold-formed structural hollow section steel with a minimum yield strength of 355 MPa and a guaranteed minimum impact energy of 27 J at -20°C, providing excellent toughness, weldability, and resistance to brittle fracture in low-temperature environments. These characteristics make the grade suitable for steel buildings, bridge structures, stadiums, industrial plants, and infrastructure projects subjected to dynamic loading. Huayang supplies ERW pipes in diameters from DN48 to DN660.4 with wall thicknesses of 2.0–22 mm. Every pipe undergoes ultrasonic weld inspection, dimensional verification, flattening tests, and mechanical property testing to ensure stable structural performance and compliance with EN10219 requirements.
