Product Description
Our steel structure bridges are designed for overseas pedestrian bridges, landscape bridges, boardwalk crossings, and small road bridge projects. We provide project-specific steel bridge fabrication solutions based on structural drawings, design requirements, site conditions, transportation constraints, and applicable local bridge standards.
The main structural components can include steel box girders, steel trusses, and steel arch members. Components are fabricated in our factory, with processes such as steel plate cutting, bevel machining, fit-up, welding, dimensional inspection, and protective coating carried out according to the approved project requirements.
To facilitate international transportation, bridge structures can be divided into transportable sections and prepared for container shipment where dimensions, weights, and shipping arrangements permit. We can also provide fabrication drawings, component identification information, installation documentation, and remote technical support to help overseas contractors coordinate assembly and on-site erection.
From fabrication planning to export preparation, our approach focuses on manufacturing consistency, traceable quality documentation, and practical installation requirements.

- Pedestrian bridges and footbridges
- Landscape bridges in parks and public spaces
- Boardwalk bridges and recreational crossings
- Small road bridges using steel box girders
- Steel truss bridges for light-duty infrastructure applications
Bridge fabrication requires close control of material traceability, weld preparation, dimensional accuracy, welding quality, and corrosion protection.
Depending on the approved drawings and inspection plan, our fabrication scope can include:
- Bridge-grade steel plate cutting and bevel preparation
- Component fit-up and welding in accordance with approved welding procedures
- Visual inspection and specified non-destructive testing (NDT)
- Dimensional inspection before shipment
- Surface preparation and application of the specified heavy-duty protective coating system
- Component marking, shipment planning, and preparation of quality records
Inspection methods, acceptance criteria, and testing coverage are defined by the project specifications and applicable standards. Where required, inspection reports and material documentation can be compiled into a project handover package.
Quality control is an essential part of steel bridge manufacturing. Depending on project specifications, inspection procedures can cover incoming material verification, weld preparation, dimensional checks, welding inspection, non-destructive testing (NDT), and coating quality.
Material certificates and applicable inspection records can be provided according to the agreed project requirements. NDT methods, testing coverage, and acceptance criteria are established in accordance with approved drawings, applicable standards, and the project inspection plan.
This documented approach helps customers and project teams review material compliance, fabrication quality, and inspection results before shipment.
