EN 10025-5 S235J0W Steel Plate | S235J0W Weathering Steel
General Description
As a professional steel plate supplier and China Mill-Direct Exporter, SHH STEEL is pleased to present EN 10025-5 S235J0W Steel Plate (Material Number: 1.8958).
S235J0W is a structural steel with improved atmospheric corrosion resistance under the European standard EN 10025-5. The “W” designation indicates enhanced resistance to atmospheric corrosion through the formation of a stable protective oxide layer (patina). It provides a minimum yield strength of 235 MPa (for thickness ≤ 16 mm) and is impact tested at 0°C with a minimum energy of 27 J. This grade is suitable for outdoor applications where moderate strength combined with good weathering performance is required, and painting costs can be reduced or eliminated.
SHH STEEL sources S235J0W plates directly from leading Chinese steel mills, ensuring competitive mill-direct pricing, stable quality and reliable delivery. We supply thicknesses from 6 mm to 150 mm, widths up to 3000–4000 mm and lengths up to 12000–18000 mm. Custom cutting, shot blasting and priming services are available. All plates are delivered with full Mill Test Certificates (EN 10204 3.1).

Delivery Conditions
SHH STEEL, as a China Mill-Direct Supplier, supplies EN 10025-5 S235J0W steel plate in as-rolled, normalized or thermomechanically rolled condition according to customer requirements.
Additional options:
- Shot blasting and shop primer
- Ultrasonic testing (EN 10160)
- Z-direction testing (Z15 / Z25 / Z35)
- Third-party inspection (SGS, BV, TUV, etc.)
Tolerances
Dimensional tolerances for S235J0W steel plate follow EN 10029.
- Thickness, width and length tolerances according to the ordered class.
- Flatness according to EN 10029.
- Edge conditions: Mill edge or cut edge (flame / plasma).
Tighter tolerances can be provided upon request.
Weldability
S235J0W has excellent weldability, similar to conventional S235 structural steels. The alloying elements added for corrosion resistance do not significantly affect welding performance when proper procedures are followed.
Recommended welding consumables:
| Welding Process | Recommended Consumables |
|---|---|
| SMAW (Stick) | E7018, E7016 |
| GMAW (MIG/MAG) | ER70S-6 |
| FCAW | E71T-1 |
| SAW | EM12K + suitable flux |
Preheating is generally not required. Matching weathering steel consumables can be used when the weld itself must also form a protective patina.
