High-strength structural steel plate with enhanced atmospheric corrosion resistance, produced to EN 10025-5 requirements. S355J2W is a weathering grade S355 that combines a minimum specified yield of 355 MPa (for thicknesses ≤ 16 mm) with improved toughness (J2 quality) and alloying that gives better resistance to atmospheric corrosion than ordinary structural steels.
Key features
- Conforms to EN 10025-5 for hot-rolled flat and long products with improved atmospheric corrosion resistance
- Grade: S355J2W (S = structural; 355 = minimum yield in MPa for t ≤ 16 mm; J2 = impact quality; W = weathering/resistance to atmospheric corrosion)
- Mechanical performance: high yield strength and good low-temperature toughness appropriate for structural applications (specific mechanical and impact values supplied per mill certificates)
- Supplied as hot-rolled plates/flat products suitable for cutting, welding and forming
Typical applications
- Structural steelwork for bridges, buildings and civil engineering
- Heavy equipment frames and chassis
- Outdoor and exposed constructions where reduced maintenance and improved corrosion resistance are required
- Work where improved toughness at lower temperatures is necessary
Supply and processing options
- Available in full plates and cut-to-size pieces; thicknesses and dimensions per EN 10025-5 production ranges
- Surface condition: hot-rolled; further processing (edge trimming, cutting, drilling, shot-blasting, priming) can be specified in the RFQ
- Delivery documentation and traceability: mill test certificates and inspection documentation can be provided on request
Ordering guidance
When requesting a quote, please specify required plate dimensions (length × width × thickness), quantity, any processing (cut-to-size, beveling, drilling), required certification level and delivery/packaging instructions. Providing expected operating environment (marine, industrial, exposed) helps select the correct grade and treatment.
For buyers seeking durable structural plates with improved atmospheric corrosion resistance and verified toughness, EN 10025-5 S355J2W is a widely used, specification-driven choice for demanding outdoor and structural applications.
