Bridge structural steel is the foundation of modern infrastructure. From long-span suspension bridges, cable-stayed bridges, and railway bridges to highway overpasses and pedestrian walkways, these steel grades must deliver exceptional strength, low-temperature toughness, fatigue resistance, and weldability under dynamic traffic loads and harsh environmental conditions.

  At Cehe Steel, we supply a complete range of Chinese bridge structural steel grades under GB/T 714-2025 (the latest revision replacing GB/T 714-2015). Our focus is not only on meeting yield and tensile requirements, but also on critical performance — including low-temperature impact toughness, weldability (CEV/Pcm control), and corrosion resistance for weathering steel grades.

  China has built some of the world's longest and most challenging bridges, and we work directly with certified mills to deliver bridge steel that meets international standards. Whether you need Q345q for general bridge construction, Q420qNH for weathering steel bridges requiring no painting, or Q690q for heavy-load long-span structures, our team provides technical support and full mill certification.

  We understand that bridge construction requires steel with consistent mechanical properties, excellent welding performance, and reliable low-temperature toughness. That's why we place equal importance on ultrasonic testing (Level II or better), grain size control, and non-metallic inclusion limits — not just the steel grade.

  In bridge engineering, safety is measured in decades. The right steel ensures structural integrity for generations.
