Rectangular/Square Hollow Section S355J2H/S42
- A hollow section is a profile with a square or rectangular cross-section, formed by hot or cold bending a steel strip and welding the edges together.
- S235, S355, E220, DC01 (in accordance with European Union standard EN10025)
- Standard length: 6000 mm and 12,000 mm
- S275JRH – structural steel (with a minimum yield strength of 275 MPa) having an impact toughness of at least 27 J at 0 °C; the designation “H” indicates that it is a hollow section.
- S235JR+AR – structural steel (with a minimum yield strength of 235 MPa) having an impact toughness of at least 27 J at 20 °C (indicated by “JR”); the designation “AR” indicates that the profile is supplied in the as-rolled condition.
- S355J2H – structural steel (with a minimum yield strength of 355 MPa) having an impact toughness of at least 27 J at –20 °C (indicated by “J2”).
