Product Specifications

Corten A Atmospheric Corrosion Resistant Steel Plate Size(mm) GNEE STEEL Supply:
(6-50)*(1600-4700)
Corten A weathering steel Delivery Condition:hot rolled
Corten A weather resistant steel Application:To be used for railway locomotives &vehicles bridges, steel towers, mastsand other structural parts.

In the initial stage of application, COR-TEN shows a yellowish appearance. This ie followed by a gradual change
in the color of the protective rust from brown to a stable dark brown after one to two years in general application
environmente. Afterwards, the coloration showe no clear change except perhape to a deeper dark brown.
Corten A Weathering Steel: Composition, Applications, and Protective Properties
Corten A is a specialized weathering-resistant alloy formulated through precise alloying of copper, chromium, and nickel, with the addition of phosphorus to optimize performance in specific environments. This unique composition enhances its suitability for gas flue systems and architectural cladding where corrosion resistance and aesthetic appeal are prioritized.While Corten A excels in these roles, it is not advised for structural applications requiring high load-bearing capacities. For such scenarios, alternatives like Corten B (with improved strength) or S355J2W steel (European weathering grade) are recommended to ensure mechanical integrity.
A defining feature of Corten A is its ability to interact with atmospheric conditions, forming a stable, self-protective patina. This oxidized layer serves dual purposes:
1. Maintenance Reduction: Eliminates the need for protective coatings, significantly lowering lifecycle costs.
2. Aesthetic Consistency: Develops a uniform, rust-toned finish over time, ideal for modern architectural facades or industrial chimneys seeking natural weathering effects.
Key applications include decorative building exteriors, exhaust stacks, and landscape elements where visual harmony with outdoor environments is desired. For projects demanding both corrosion resistance and structural robustness, Corten B’s higher tensile strength and carbon content offer a balanced solution.
