-
High-strength, weathering structural steel plate engineered for external applications where improved atmospheric corrosion resistance is required. EN10025-5 S355J2W offers structural-grade mechanical properties combined with enhanced resistance to rusting, making it suitable for exposed structures without heavy protective coatings.
-
Available grades: S355J2W (EN10025-5), plus related weathering grades S355J0W and S355K2W. Some grades have properties comparable to commercially known weathering steels (often marketed as Corten-equivalents).
-
Typical product forms: hot-rolled plates, sheets, coils and cut sections for structural fabrication.
Key specifications
- Thickness: coil thickness ≤ 25 mm (plates available in thicker gauges as stock allows)
- Width: 1,220 – 4,200 mm
- Length: 5,000 – 18,000 mm
- Minimum order quantity (MOQ): 10 pieces
- Stock status: commercial stock available for prompt delivery; production lead time typically 10–40 days when out of stock
- Documentation: Material Test Certificate (MTC) available
Mechanical, testing and processing options
- Standard and optional heat treatments: AR (as hot rolled), TMCP (thermo-mechanical control processing), N (normalized), Q+T (quenched and tempered)
- Mechanical and quality tests available: Charpy V-notch impact testing, Z-direction testing (Z15, Z25, Z35), NDT (UT, ultrasonic examination), PWHT (simulated post-weld heat treatment), HIC testing, and third-party inspection (e.g., SGS)
- Surface and finishing: shot blasting, coating on request
- Corrosion and service standards: NACE MR0175 inspection and related surface preparation available upon request
Typical applications
- Bridges, structural steelwork, architectural façades and cladding, outdoor storage tanks, heavy equipment and other welded structures exposed to the atmosphere where reduced maintenance and enhanced weather resistance are important.
Commercial terms
- Delivery: immediate for stocked items or 10–40 days for production
- Payment terms: T/T or Irrevocable L/C at sight
- Standard packaging and export preparation included; bespoke cutting, edge preparation or coating available on request
For procurement teams: specify required grade (S355J2W / S355J0W / S355K2W), exact dimensions (thickness × width × length), required testing/certification and desired delivery schedule when requesting a quote.
