Product Overview

Weathering Corten steel plate is an atmospheric corrosion-resistant structural steel designed for long-term outdoor service environments. Manufactured according to ASTM A242, GB/T4171, EN 10025, and JIS weathering steel standards, it provides durable performance for architectural, transportation, and industrial outdoor projects.

The product covers multiple global grade systems, including Corten A, Corten B, ASTM A588 Gr.A/B/C/K, ASTM A242, ASTM A709 Gr.50W, S355J0WP, S355J2W, S355K2W, SPA-H, SPA-C, Q235NH, Q345NH, Q355NH, and Q355GNH, meeting different regional engineering requirements.

Unlike ordinary steel, Corten weathering steel forms a dense and stable protective rust patina layer naturally when exposed to outdoor atmospheric conditions. This protective layer reduces the need for regular painting and anti-corrosion maintenance while maintaining good welding, cutting, bending, and forming performance.

With thicknesses from 1.5–100mm, multiple width and length options, steel plate and coil supply, and customized cutting services, the product is widely used in outdoor sculptures, building curtain walls, landscape structures, shipping containers, railway vehicles, bridge structures, and power plant chimneys.
