Q235B Equal Angle Steel 20×20×3mm ~ 200×200×20mm

Structural steel refers to steel that meets specific strength and formability grades; its formability is typically characterized by the post-fracture elongation in tensile tests. It is primarily used in the manufacture of load-bearing structural components. Its classifications include carbon structural steel and low-alloy high-strength structural steel, among others. Steel structures are widely used in various fields, including construction, bridge engineering, and mechanical manufacturing.
