Product Description:
EN 10155 S355J2WP is a high-strength, weather-resistant structural steel plate designed to form a stable rust-like protective patina when exposed to atmospheric conditions, eliminating the need for painting. Its unique alloy composition provides superior corrosion resistance, making it ideal for bridges, building facades, shipping containers, and other outdoor structures exposed to harsh environments. The self-protecting oxide layer regenerates continuously, ensuring long-term durability with minimal maintenance requirements.
Key Features:
Excellent Weather Resistance – Develops a protective patina layer to resist atmospheric corrosion
High Strength – Minimum yield strength of 355 MPa
Low Maintenance – No painting required, reducing lifecycle costs
Weldable & Fabrication-Friendly – Suitable for structural and architectural applications
