What is EN 10210 Hot Finished CHS?
The EN 10210 standard represents the European specification for hot-finished structural hollow sections of non-alloy and fine-grain steels.
- Hot Finished (HF): Unlike cold-formed sections, these tubes are completely formed at high temperatures (typically above 850℃ to 900℃) or fully heat-treated after forming. This thermal process eliminates all residual manufacturing stresses, refines the steel's grain structure, and ensures completely uniform strength throughout the cross-section.
- CHS (Circular Hollow Section): The geometric round profile offers omnidirectional structural strength-delivering equal resistance to bending, buckling, and torsional (twisting) forces from any direction.

Frequently Asked Questions (FAQs)
FAQ
Q: What is the primary difference between EN 10210 and EN 10219 structural tubes?
A: The main difference lies in the manufacturing process and internal stress. EN 10210 specifies hot-finished hollow sections, which are stress-free and deliver uniform mechanical properties. EN 10219 specifies cold-formed welded hollow sections, which retain high internal residual stresses from the cold rolling process. EN 10210 tubes are preferred for critical, highly stressed structural components and applications requiring extensive on-site fabrication.
Q: Why is the S355J2H grade so popular for outdoor construction?
A: Under the EN 10210 standard, S355J2H represents structural steel with a minimum yield strength of 355 MPa. The "J2" suffix guarantees that the material has been impact-tested to withstand at least 27 Joules of energy at -20°C. This means it retains its toughness and resists brittle failure even in freezing environments and under dynamic weather loads.
Q: How do you protect the hollow sections from rusting during long ocean voyages?
A: For standard export shipments, we apply an environmentally safe anti-rust varnish or light protective oil to the exterior surfaces. To provide maximum security against sea-salt humidity, the pipes are bundled with heavy-duty steel bands and can be wrapped in thick, waterproof PVC woven sheets with protective plastic end caps.
Q: Do you support custom beveling and third-party inspections?
A: Absolutely. We provide precise factory beveling to prepare your pipe ends for immediate on-site structural welding. We also fully welcome international third-party inspection (TPI) agencies like SGS, Bureau Veritas (BV), or TÜV to verify product dimensions, mechanical properties, and packaging before shipment.
