Our products are mainly exported to the Middle East, Southeast Asia, Europe, New Zealand, and other regions.If you would like to learn more about our products, feel free to contact us and send your purchase list.
Standard Composition
The EN10210 standard consists of two parts:
- EN 10210-1 - Technical delivery conditions, covering chemical composition, mechanical properties, and testing requirements.
- EN 10210-2 - Tolerances, dimensions, and sectional properties, specifying permissible variation in wall thickness, outside dimensions, mass, and geometric properties used for structural design calculations.
Common Steel Grades
| Grade | Description |
|---|---|
| S235JRH | Standard structural grade, general purpose |
| S275J0H | Improved impact toughness at 0°C |
| S275J2H | Improved impact toughness at -20°C |
| S355J0H | Higher strength, impact tested at 0°C |
| S355J2H | Higher strength, impact tested at -20°C |
| S355K2H | Higher strength, enhanced impact toughness at -20°C |
The "H" suffix denotes hollow section. Grade selection typically depends on the design strength requirement and the minimum service temperature the structure will experience.

FAQ
Q: What is the difference between EN10210 and EN10219 hollow sections?
A: EN10210 covers hot finished hollow sections, while EN10219 covers cold formed hollow sections. Hot finishing relieves internal stress from the forming process and generally produces more rounded corners and more uniform mechanical properties, particularly at the corner radii. Cold formed sections (EN10219) can have increased strength at the corners due to cold working, but with correspondingly reduced ductility in that area. The correct choice depends on the structural design code and project specification.
Q: What does the "H" mean in grades like S355J2H?
A: The "H" suffix specifically denotes that the grade applies to hollow sections, distinguishing it from the equivalent flat/plate steel grade (e.g., S355J2 for plate versus S355J2H for hollow section), since mechanical property requirements can differ slightly by product form.
Q: Can EN10210 hollow sections be hot-dip galvanized?
A: Yes. Hot-dip galvanizing is a common post-production finishing option for EN10210 hollow sections used in outdoor or corrosive environments, and is typically applied after fabrication is complete.
Q: What certification should I request when ordering?
A: At minimum, request a Mill Test Certificate per EN 10204 3.1, which confirms chemical composition and mechanical properties. For projects with stricter compliance requirements, EN 10204 3.2 certification with independent third-party inspection may be required.
