Structural Steel Grades
High-quality structural steels for buildings, bridges, machinery, and heavy engineering applications, offering optimal balance of strength, weldability, toughness, and formability.
Structural Steel Categories
Structural steels are engineered for buildings, bridges, machinery, industrial fabrication, and heavy engineering applications. Selection depends on required strength, weldability, toughness, formability, and environmental conditions. Common classifications include ASTM grades, European EN standards, high-strength low-alloy (HSLA) steels, and weathering steels.
ASTM Structural Grades
American standard structural steels offering excellent weldability and formability for general construction and heavy engineering applications.
EN European Grades
European standard structural steels (EN 10025) providing graduated strength levels for various construction and industrial applications.
HSLA & Weathering Steels
High-strength low-alloy and weathering steels offering enhanced strength, corrosion resistance, and reduced maintenance for bridges and outdoor structures.
Special Structural Grades
Specialized structural steels for specific applications requiring unique combinations of strength, corrosion resistance, and fabrication properties.
