S355J0WP-EN 10025-5 Corten Steel Plate

Product Introduction

S355J0WP is a structural weather-resistant steel grade under EN 10025-5 standard. It is specially designed for use in outdoor environments where durability and resistance to atmospheric corrosion are essential.

This steel contains alloying elements such as copper, chromium, and phosphorus, which help form a stable oxide layer on the surface—known as a protective patina —reducing the need for painting or coating over time.

Key Characteristics

• Excellent Corrosion Resistance: Forms a protective rustForms a protective rust layer when exposed to the atmosphere, minimizing further corrosion.

• Structural Strength: YieldYield strength ≥ 355 MPa, suitable for heavy-duty and load-bearing applications.

• Environmentally Friendly: Eliminates the need for painting in most outdoor settings, reducing VOC emissions and long-term maintenance costs.

• EN Standard Certified: Complies with EN 10025-5 for weathering structural steels.
