GB angle steel provides several core advantages:
Cost-Effectiveness: As a carbon steel, it is 10–15% cheaper than alloy steels like Q355, making it ideal for budget-sensitive projects.
Mechanical Performance: With yield strengths of 235–345 MPa (Q235/Q355 grades), it balances strength and ductility (elongation ≥26% for Q235), suitable for both static and dynamic loads.
Formability & Weldability: Low carbon content allows easy cutting, bending, and welding. For instance, Q235 angle steel can be welded without preheating in most thicknesses, reducing fabrication time.
Standardization: Complies with GB/T 706, ensuring consistent quality and widespread availability in China and export markets.
