S355J2WP-EN 10025-5 Corten Steel Plate

S355J2WP Corten steel plate is a high- strengthis a high-strength, low-alloy structural steel with enhanced atmospheric corrosion resistance. Designed in accordance with EN 10025-5 , this material is part of the Corten family of weathering steels , which naturally develop a stable, rust-like appearance when exposed to the elements.

What makes S355J2WP stand out is its excellent cold-weather toughness (impact tested at -20°C) and its ability to age beautifully outdoors without the need for painting or protective coating.

What Is Corten Steel?

Often referred to as “rusted steel” or “weathering steel” , Corten steel forms a protective oxide layer that slows down future corrosion. The result is a distinctive reddish-brown patina that evolves over time—ideal for architectural, landscaping, and structural uses .
