S355J2H Square tube

EN10210 S355J2H SHS,RHS and CHS Hollow Sections

S355J2H structural hollow sections to perform in even the most arduous conditions. EN10210 S355J2H hot formed hollow section is the product to choose for all critical structural applications where the only option is success.


S355J2H key features:

  • Hot finished, so free of internal stresses and with a minimum strength of 355 MPa – allowing the highest fabrication factors and enabling material cost savings and lighter structures
  • Available in a wide range of circular (CHS), square (SHS), rectangular (RHS), elliptical, half-elliptical, flat-oval, octagonal, hexagonal and triangular hollow sections
  • Tight corner radii, exceeding the standard - enhancing the product’s aesthetic appeal whilst avoiding the risk of brittle fracture which occurs in some cold formed products
  • Dimensional consistency, high levels of formability and, because the steel is fully-killed, excellent weldability
  • Certified as suitable for all structural applications, fully compliant with design codes and overcomes design risks associated with cold formed products
  • Certified as suitable for mechanical applications, especially those involving cyclical loading
  • Suitable for low temperature applications (-20°C)
  • Batch-tested to give the properties of the specific delivered material; full test certification supplied
  • Clearly marked as S355J2H, with the reassurance of batch traceability
  • Full technical support available
  • Also available certified to a normalised fine grain S355 NH condition
  • S355J2H RHS, SHS, CHS, Elliptical, Half-Elliptical, Flat-Oval, Octagonal, Hexagonal and Triangular Hollow Sections are CE marked and fully compliant to the Construction Products Directive
  • Suitable for galvanising
