Description

A Suspension Bridge is a long-span steel bridge structure in which the deck is suspended from main cables anchored at both ends and supported by towers. It is widely used for rivers, bays, valleys, highways, railways, pedestrian crossings, and landmark infrastructure projects where ultra-long spans and high clearance are required.

Our suspension bridges are fabricated using high-strength structural steel such as Q355, Q460, S355, ASTM A572, combined with high-tensile steel wire cables, ensuring excellent load capacity, wind resistance, and long-term structural safety even under extreme environmental conditions.
