High-strength weathering (Corten) structural plate manufactured to EN 10025-5 specification. S355J0WP is a hot‑rolled, atmospheric‑corrosion‑resistant steel grade designed for exposed applications where the formation of a protective rust patina reduces long‑term maintenance compared with ordinary carbon steels.
Key features
- Conforms to EN 10025‑5 weathering steel requirements (S355J0WP).
- Minimum yield strength: 355 MPa; typical tensile strength range ~470–630 MPa.
- J0 / J2 / K2 denote impact‑test classes (progressively lower test temperatures: J0 ≈ 0 °C, J2 ≈ −20 °C, K2 ≈ −50 °C) to suit different low‑temperature service conditions.
- W indicates improved atmospheric corrosion resistance; P denotes controlled phosphorus/sulfur limits to support weathering performance.
- Supplied as hot‑rolled plate with a range of thicknesses and cut‑to‑size options available to meet project requirements.
- Good weldability and formability for conventional fabrication methods; recommended welding/fabrication procedures should be followed to preserve weathering properties.
Typical applications
- Offshore and coastal structures exposed to sea air
- Bridges, gantries and structural members where long‑term atmospheric corrosion resistance is required
- Shipping containers, storage tanks and outdoor equipment
- Architectural façades, landscaping and public art where the natural patina is desired
Supply options and quality
Plates are offered in multiple sizes and thicknesses and can be supplied to project specifications. Material certificates and test reports (showing compliance with EN 10025‑5 and agreed mechanical/chemical properties) can be provided on request to support procurement and inspection requirements.
For quotes, specify required thickness, plate dimensions, impact class (J0/J2/K2 if applicable), surface condition and any certification or inspection requirements.
