EN 10219 S355J2H steel pipe is a premium cold-formed welded structural hollow section designed for load-bearing applications. Manufactured under the European EN 10219 standard, it is available in CHS, SHS, and RHS profiles.
The "S355" designation guarantees a minimum yield strength of 355 MPa, providing excellent structural capacity. The "J2" suffix ensures superior impact toughness at -20°C, making it ideal for cold environments and dynamic loading. The "H" signifies its use as a hollow section.
While offering good weldability, S355J2H requires protective coatings like galvanizing for outdoor use. Proper selection requires evaluating structural loads, dimensions, and environmental conditions.
What Is EN 10219 S355J2H Steel Pipe?
EN 10219 S355J2H steel pipe is a cold-formed welded structural hollow section made from non-alloy structural steel. It is designed primarily for load-bearing structures rather than for transporting fluids under pressure. The product is manufactured according to the EN 10219 series, which specifies technical delivery conditions for cold-formed welded structural hollow sections.

Key Takeaway
The main performance characteristics of EN 10219 S355J2H can be summarized as:
-
High structural strength – 355 MPa yield
-
Specified low-temperature toughness – J2 impact
-
Good weldability – fabrication-friendly
-
Efficient hollow-section geometry – CHS, SHS, RHS

S355J2H Steel Pipe vs. Other Structural Steel Grades
When selecting a structural hollow section, EN 10219 S355J2H is often compared with other grades such as S235JRH, S275J2H, and S355J0H. These grades may look similar, but their strength levels, impact toughness requirements, and intended service conditions can differ. The correct choice should be based on the structural design rather than simply selecting the highest-strength grade.

Key Takeaway
EN 10219 S355J2H steel pipe is well suited to structural applications where strength, toughness, weldability, and efficient hollow-section geometry are important.
From building frames and bridges to industrial structures and equipment supports, it provides a versatile solution when the grade, profile, wall thickness, and surface protection are properly matched to the project requirements.
How to Select the Right S355J2H Steel Pipe
Selecting the right EN 10219 S355J2H steel pipe requires more than confirming the steel grade. Because S355J2H is primarily used as a structural hollow section, engineers should consider the structural loads, section shape, dimensions, operating environment, fabrication requirements, and applicable standards.
