Product Overview
S355J0WP, S355J2WP, S355K2W are European standard weathering steel grades manufactured according to EN 10025-5. They are structural steel plates with atmospheric corrosion resistance, designed for applications where long-term durability and reduced maintenance are required.
S355J0WP is a phosphorus-alloyed weathering steel suitable for general outdoor structural parts and thinner plates. S355J2WP offers improved low-temperature impact toughness compared with S355J0WP, making it more suitable for structures exposed to colder climates. S355K2W provides the highest toughness level in this group, with better impact performance at low temperatures, suitable for heavy structural components and demanding engineering projects.
These grades contain copper, chromium and nickel, which promote the formation of a dense and stable protective rust layer under alternating dry and wet atmospheric conditions. This property allows the steel to be used without continuous painting in many outdoor environments.
The S355J0WP, S355J2WP and S355K2W series is widely used in building facades, pedestrian bridges, highway structures, railway infrastructure, landscape architecture and industrial buildings. We can supply plates in various thicknesses and support cutting, bending, welding and fabrication according to customer drawings.

FAQs
They are all EN 10025-5 weathering steels, but differ in impact toughness. S355J0WP is for general use, S355J2WP offers better low-temperature toughness, and S355K2W provides the highest toughness level.
Yes, S355J0WP is weldable by conventional methods. However, due to its higher phosphorus content, welding procedure control is recommended for thicker or restrained structures.
Yes, S355K2W has higher low-temperature impact toughness, making it more suitable for structural components exposed to cold or demanding service conditions.
Yes, we provide EN 10204 3.1 or 3.2 mill test certificates for each batch, including chemical composition and mechanical properties.
MOQ is 5 tons. In-stock goods can be delivered within 3–7 days, while customized production usually takes 10–25 days.
