Introduction

Corten Steel S355J2W+N Sheets are strong weather-resistant steel sheets used in construction, industrial, and architectural applications. These sheets are specially designed to resist corrosion and harsh weather conditions. Because of their excellent strength and long life, they are widely used in outdoor structures and heavy-duty projects.

The steel develops a protective rust-like layer on the surface when exposed to air and moisture. This layer protects the material from further corrosion and increases its durability.


What is Corten Steel S355J2W+N?

S355J2W+N is a grade of weathering steel known for its high strength and excellent atmospheric corrosion resistance. The “W” in the grade represents weather-resistant properties, while “+N” means the steel is normalized or normalized rolled for better toughness and strength.

Unlike ordinary carbon steel, this material can naturally protect itself from environmental damage. It is commonly used in structures exposed to rain, humidity, pollution, and changing weather conditions.


Features of Corten Steel S355J2W+N Sheets

Excellent Corrosion Resistance

These sheets offer better corrosion resistance than standard steel. The protective oxide layer helps prevent deep rusting.

High Strength

S355J2W+N sheets have excellent mechanical strength, making them suitable for heavy structural applications.

Long Service Life

Because of their weather-resistant properties, these sheets can last for many years with minimal maintenance.

Low Maintenance

The sheets do not require frequent painting or surface coating, which helps reduce maintenance costs.

Attractive Appearance

The rust-colored surface gives the sheets a modern and industrial look, making them popular in architecture and design projects.

Easy Fabrication

These sheets can be easily cut, welded, bent, and formed according to different project needs.


Chemical Composition

Corten Steel S355J2W+N Sheets contain elements such as:

  • Carbon
  • Manganese
  • Silicon
  • Copper
