Corten Cost Per Square Foot

Corten steel cost per square foot depends mainly on whether the material is produced under Chinese GB standards or international ASTM/EN/JIS standards. Domestic grades such as Q355NH offer a more cost-effective solution for landscaping and architectural use, while international grades like ASTM A588 and S355J2W provide stricter performance standards and are typically used in higher-end engineering and export projects. Thickness, surface treatment, and processing requirements also significantly affect the final cost.
