Our Steel truss bridge represents the pinnacle of standardized structural engineering for large-span crossings and heavy-duty industrial access. Since 2010, our factory has been specializing in gantry and H-beam truss designs that provide immense rigidity and load-bearing capacity. By utilizing a "Truss" logic-where structural members are arranged in triangles-we create a bridge that can span up to 36 meters with minimal deflection. Each Steel truss bridge we manufacture in our 10,000-square-meter facility is built using National Standard H-beams and I-beams, ensuring that your infrastructure is as robust as the industrial plants we build for Fortune 500 companies.
At our Suzhou plant, we prioritize "Standardized Practice" and "Advanced Technology." Every Steel truss bridge undergoes a complete workshop pre-assembly to ensure that all high-strength bolted connections are perfectly aligned. This is critical for bridges being shipped to remote areas where on-site modifications are impossible. We utilize Sa2.5 shot blasting and a multi-layer industrial coating system to ensure the bridge survives decades of exposure to the elements. As a National AAA-Level Credit Enterprise, we offer a "Zero Defect" guarantee, providing a reliable, earthquake-resistant, and high-strength crossing for your town's main roads or your factory's heavy vehicle lanes.
Application Fields
The Steel truss bridge is the ideal choice for crossing medium to large rivers, bridging roadway interchanges, and providing heavy-duty vehicle access to industrial plants and mining sites. It is also an excellent solution for permanent municipal road bridges in town centers.
Customization & Technical Support
We offer full OEM/ODM services, customizing the truss height and girder thickness to meet your specific span and load requirements. Our R&D team provides full 3D CAD drawings and 24/7 remote video support to assist your local installation team. With over 15 years of experience in more than 20 countries, we ensure your Steel truss bridge meets all relevant international engineering and safety standards.
Packaging & Shipping
Truss members are bundled in sea-worthy metal frames, and all hardware is shipped in reinforced boxes. We export through Shanghai Port and can provide comprehensive logistics support under EXW or FOB terms.

FAQ
Q: Can a truss bridge handle very heavy trucks?
A: Yes, the Steel truss bridge is specifically designed for high-load applications, including heavy industrial transport and large-scale agricultural machinery.
Q: How long is the design life?
A: With proper initial coating (which we provide) and periodic maintenance, our steel truss bridges are designed for a service life of 30 to 50 years.
Q: What is the maximum span without a mid-river pier?
A: We can design a single-span truss bridge up to 36 meters, depending on the load and bridge width. For longer crossings, we use a multi-span approach.
