Durability and rapid deployment are the hallmarks of our Corrugated section steel bridge. For 15 years, our factory has specialized in "arch-effect" engineering, utilizing the inherent strength of corrugated sections to create spans that require no internal supports. By rolling Q235B or Q355B steel into specific corrugated profiles, we create a structure that excels in both compression and load distribution. Our Corrugated section steel bridge is designed as a circular or arch-shaped assembly, which allows it to handle significant soil overburden and heavy vehicle loads, making it a superior alternative to traditional box culverts or small beam bridges.
Our commitment to "Survival through Quality" is evident in the manufacturing process of every Corrugated section steel bridge. In our Suzhou facility, we use CNC technology to punch the ring-direction bolt holes, ensuring that the modular sections fit together perfectly during site assembly. This eliminates the need for expensive on-site welding or heavy lifting equipment. As an ISO-certified manufacturer, we provide hot-dip galvanization for all sections, ensuring the bridge resists corrosion from soil and water for a service life of 30+ years. Whether you are building a mining haul road or a municipal road bypass, our corrugated sections provide a high-strength, flexible, and cost-effective solution.
Application Fields
The Corrugated section steel bridge is the premier choice for highway underpasses, mining haul road culverts, industrial park access bridges, and municipal stormwater drainage systems. Its arching strength makes it ideal for areas with heavy vehicle traffic and deep soil fill.
Customization & Factory Strength
We offer full OEM/ODM services for custom arch profiles and spans. Our R&D team utilizes advanced structural modeling to ensure the Corrugated section steel bridge meets your specific load requirements. We provide 24/7 remote video support to guide your team through the assembly of the modular sections, ensuring a safe and compliant installation.
Packaging & Shipping
Sections are nested together to save container space and secured with steel strapping. Small components and bolts are shipped in reinforced boxes. Export is via Shanghai Port.

FAQ
Q: Why use corrugated steel instead of concrete?
A: It is 50% faster to install, requires no curing time, can handle ground settlement better due to its flexible nature, and is significantly easier to transport to remote locations.
Q: What is the maintenance requirement?
A: Due to the high-grade hot-dip galvanization, the Corrugated section steel bridge requires almost no maintenance other than periodic cleaning of the water channel.
Q: Can you produce very large spans?
A: We can manufacture single spans up to 20 meters. For larger requirements, we can design multi-arch systems.
