Structural steel

High strength steel
High-Strength Steel (HSS) is an advanced steel material with superior mechanical properties, offering yield strengths ranging from 345MPa to over 1600MPa. Through optimized alloy composition and advanced manufacturing processes (e.g., TMCP, QT), HSS provides excellent strength while maintaining good ductility, weldability, and weather resistance. It is widely used in construction, engineering machinery, automotive manufacturing, and energy equipment.
