Description
A Cable-Stayed Bridge is a modern long-span bridge structure in which the bridge deck is directly supported by stay cables connected to one or more towers (pylons). Compared with suspension bridges, cable-stayed bridges feature stronger structural stiffness, lower construction cost, and easier maintenance, making them widely used in highways, urban expressways, rail transit systems, river crossings, and landmark infrastructure projects.
Our cable-stayed bridges are fabricated using high-strength structural steel such as Q355, Q460, S355, ASTM A572, combined with high-tensile steel stay cables, delivering excellent load capacity, wind resistance, and long-term durability under complex environmental conditions.
