Hot‑rolled structural steel plate produced to the S355J0W grade — a weathering (atmospheric corrosion resistant) variant of the S355 family. Supplied as hot‑rolled flat plates, S355J0W combines high yield strength with improved resistance to atmospheric corrosion, making it suitable for outdoor structural applications where reduced maintenance and longer service life are required.
Key features
- Weathering steel with enhanced atmospheric corrosion resistance ("W" grade).
- High minimum yield strength consistent with the S355 family (nominal 355 MPa range), offering good load‑bearing capacity for structural use.
- Toughness and impact testing at 0°C indicated by the J0 designation.
- Good weldability, formability and machinability for standard structural fabrication processes (cutting, welding, bending).
- Typical uses: bridges and civil structures, building frames and cladding, towers and masts, outdoor containers and equipment, and other components exposed to the elements.
Supply and processing options
- Available in plate format for direct use in fabrication; can be supplied full‑plate or cut‑to‑size to customer drawings.
- Ready for conventional thermal cutting, drilling and welding procedures used for structural steels.
- Can be coated or painted for additional protection where required, but often left to develop a protective patina in outdoor environments.
Quality and specification notes
- S355J0W is produced to the EN S355 family technical delivery conditions for weathering steels (refer to applicable EN specifications for order detail and inspection requirements).
- Buyers should specify required thickness, dimensions, surface condition, certification (mill test reports, inspection), and any additional processing when requesting quotations.
Contact and ordering
For pricing, available dimensions and lead times, submit an RFQ with required plate dimensions, quantity and any required certifications or processing. Typical commercial plate sizes referenced include examples such as 8×2200×8000 mm, 16–20×2000×8000 mm and 40×2000×8000 mm; confirm exact stock and prices with supplier at time of enquiry.
