S355J2G2W steel plate

S355J2G2W is a structural weathering steel grade specified in EN 10155, designed for improved resistance to atmospheric corrosion while retaining high strength and good weldability. It is widely used where long-term exposure to the elements is expected and structural performance is required.

Key features

• Standard: EN 10155
• Grade: S355J2G2W (minimum yield strength ~355 MPa)
• Atmospheric corrosion resistant (weathering steel)
• Impact requirement: J2 (low-temperature impact properties)
• Available thickness: up to 220 mm
• Product forms: coils, sheets, plates
• Finishes: hot-rolled plate (HR), cold-rolled sheet (CR)

Available processing and services

• Cutting, drilling, welding, grinding, milling
• Mechanical and/or metallurgical testing as required

Typical applications

• Structural steelwork for buildings and civil engineering
• Bridges and infrastructure
• Offshore and coastal structures where enhanced atmospheric corrosion resistance is required
• Heavy fabrication and machinery components

Ordering notes

• Specify required thickness, dimensions, surface finish and any machining or testing services at order stage
• Confirm delivery form (coils, sheets or full plates) and required edge/finish tolerances

This material is suitable for projects that need a combination of structural strength and improved resistance to atmospheric corrosion. For precise mechanical/chemical requirements, reference EN 10155 and provide required inspection or testing criteria when placing orders.
