Product Description: Rectangular Tubes Cor-Ten / S355J0WP / S355J2WP
Rectangular and square hollow sections made of Cor-Ten, S355J0WP, and S355J2WP are high-strength structural steel products with enhanced resistance to atmospheric corrosion. The material develops a stable protective oxide layer (patina) that prevents further corrosion and significantly extends service life without additional protective coatings.
General Technical Characteristics
S355J0WP and S355J2WP belong to the weathering steel (atmospheric corrosion-resistant steel) category. They combine the high strength of S355 structural steel with improved corrosion resistance, eliminating the need for painting or galvanizing in many applications.
Key properties:
- high atmospheric corrosion resistance;
- enhanced durability in outdoor environments;
- high structural strength (S355 grade);
- long service life without additional protection;
- formation of a protective patina layer.
Chemical Composition
The steel typically contains:
- Iron (Fe) – base element;
- Copper (Cu) – key element for weather resistance;
- Chromium (Cr) – improves corrosion resistance;
- Nickel (Ni) – enhances durability;
- Phosphorus (P) – contributes to patina formation;
- Carbon (C) and Manganese (Mn) – ensure mechanical strength.
Mechanical Properties
The material provides:
- high S355-grade strength;
- good impact toughness;
- excellent atmospheric corrosion resistance;
- long-term structural stability;
- good weldability.
Applications
Cor-Ten / S355J0WP / S355J2WP rectangular tubes are used for manufacturing:
- architectural structures;
- façade systems;
- bridges and outdoor constructions;
- frames and support structures;
- landscape and design projects;
- industrial building structures.
The material is widely used in modern architecture due to its distinctive rust-like decorative appearance and minimal maintenance requirements.
Features
Key advantages include:
- decorative stable patina without material degradation;
- no need for painting or coating;
- long service life;
- high structural strength;
- excellent weather resistance.
Supply Formats and Standards
The material is supplied as:
- square hollow sections (SHS);
- rectangular hollow sections (RHS);
- structural steel tubes for fabrication.
Grades:
- Cor-Ten (weathering steel equivalent);
- S355J0WP;
- S355J2WP.
Cor-Ten / S355J0WP / S355J2WP rectangular tubes are reliable and durable materials for modern architectural and construction solutions, combining structural strength with excellent atmospheric corrosion resistance.
