EN 10025-2 S235JR is a European standard grade for hot-rolled structural steel beams, including H-beams, I-beams, universal beams, and columns, with a minimum yield strength of 235 MPa.
Its equivalent grades in other international standards provide similar mechanical performance, making S235JR beams widely interchangeable for global sourcing and engineering projects.
Common equivalent grades for S235JR structural beams include:
ASTM A283 Grade C (USA)
A carbon structural steel with comparable yield and tensile strength, commonly used for general construction beams and columns.
DIN St37-2 (Germany)
A non-alloy structural steel with similar mechanical properties and weldability, widely used for machinery frames and building beams.
JIS SS330 / SS400 (Japan)
Hot-rolled steels for general structural use, suitable for welded beam applications with comparable strength levels.
GB Q235B (China)
A low-carbon structural steel beam grade with equivalent yield strength, extensively used in buildings, workshops, and equipment structures.
NF A E24-2 (France)
A traditional structural steel grade with similar composition and performance for construction beams.
UNI Fe 360 B (Italy)
A non-alloy structural steel with comparable tensile strength for general-purpose beams and columns.
BS 40 B (UK)
An older British structural beam grade with matching strength levels for welded structures.
UNE AE 235 B (Spain)
A structural steel beam grade with similar characteristics for civil and industrial engineering.
These equivalents are based on similar chemical limits, yield strength levels, and structural performance, but direct substitution should always be verified against project specifications.
For higher-strength beam alternatives, see EN 10025-2 S275JR, S275J0, or S355 structural beam grades.

Key Notes:
S235JR beams maintain low P and S levels, improving toughness and weld integrity.
ASTM A283 Gr C beams allow higher carbon, suitable for general structural use but with broader tolerances.
DIN St37-2 and GB Q235B beams closely match S235JR in weldability and strength.
JIS SS330 beams favor lower carbon for improved formability.
Gangsteel supplies structural beams meeting multiple standards, simplifying cross-standard substitution.
EN 10025-2 S235JR Mechanical Properties Comparison
Mechanical properties of S235JR beams and equivalent grades are closely aligned. EN 10025-2 uniquely specifies impact toughness, which enhances safety against brittle fracture.
Mechanical Properties (Beams, ≤16 mm thickness)
| Property | S235JR | ASTM A283 Gr C | DIN St37-2 | JIS SS330 | GB Q235B |
|---|---|---|---|---|---|
| Yield Strength (min, MPa) | 235 | 205 | 235 | 205 | 235 |
| Tensile Strength (MPa) | 360–510 | 380–515 | 340–470 | 330–430 | 375–500 |
| Elongation (min, %) | 26 | 25 | 26 | 26 | 26 |
| Impact Test | 27 J @ +20°C | Not specified | Not specified | Not specified | Not specified |
Key Notes:
S235JR beams guarantee Charpy impact toughness at +20°C.
ASTM and JIS beam grades generally do not mandate impact testing unless specified.
GB Q235B beams match well in yield strength but may require additional testing for low-temperature service.
Gangsteel supplies tested beams with full EN 10204 certificates for engineering assurance.
EN 10025-2 S235JR Applications and Substitution Considerations
S235JR structural steel beams are widely used in:
Building structures (beams, columns, frames)
Bridges and pedestrian structures
Machinery frames and industrial supports
Offshore and onshore platforms (non-low-temperature critical zones)
Substitution Guidelines:
US projects: ASTM A283 Gr C beams may be substituted for general applications.
European machinery: DIN St37-2 beams are commonly accepted.
Cold or dynamic loading: EN grades are preferred due to mandatory impact testing.
Certification requirements:
CE marking → EN 10025 beams
AWS / AISC → ASTM beams
For low-temperature beam applications, consider:
EN 10025-2 S355J2
EN 10025-5 S355K2
