S235JR
Data verifiedS235JR is the baseline non-alloy structural steel of EN 10025-2, the default grade for ordinary steel construction across Europe. Its 235 MPa yield class and room-temperature impact guarantee cover the great majority of building and general fabrication work.

FAQ
- S235JR vs Q235B?
- Same strength class and very close chemistry; the standards differ mainly in impact-test and inspection requirements. Mill certificates are usually cross-accepted for non-critical work.
