The 24-meter CB100 Bailey Bridge, designed by our company for Changdu, Tibet, is a modular steel bridge product tailored to the harsh high-altitude environment of the Tibetan region. The bridge features a double-lane single-layer structure, accurately matching the 24-meter span requirement, and its load-bearing performance meets the local transportation needs. Given the high altitude, intense ultraviolet radiation, large day-night temperature variations, and frequent rain and snow in Changdu, the bridge is treated with professional paint-based corrosion protection to effectively resist corrosion and enhance its service life in harsh outdoor environments. Leveraging the modular advantages of the CB100-type, the bridge components are highly standardized, and on-site assembly does not require large machinery, ensuring efficient construction. The structure is stable, and operation and maintenance are convenient, providing a reliable bridge solution for local transportation.
