Standardized panels for precise bridge planning
The Type 321 Bailey Bridge uses a 3,000 mm longitudinal panel module and a 1,400 mm vertical pin-hole center spacing. These dimensions give engineers a clear basis for planning panel quantities, truss connections and the overall bridge arrangement. For contractors ordering a prefabricated modular steel bridge, identifying the exact panel type also helps prevent confusion with other Bailey bridge systems. Production dimensions and connection details are confirmed against the approved drawings for each order.
Structural configurations developed around the project
No single truss arrangement suits every crossing. Type 321 panels can be combined with the rows, layers and reinforcing components specified by the project design. Tuotian reviews the required span, clear deck width, vehicle axle loads and support conditions before preparing a proposed configuration. This project-based approach is particularly useful for a temporary road bridge, where construction traffic and the condition of the crossing may differ from one site to another.
Prefabricated components for organized site installation
Type 321 Bailey Bridge components are manufactured before shipment and assembled at the installation site. Contractors can therefore plan delivery, lifting and installation around a defined set of bridge sections and connection parts. The modular format is useful where extensive on-site steel fabrication would be difficult. Installation methods and schedules still depend on site access, lifting equipment, foundations and an approved construction plan; they are confirmed for the actual project rather than assumed from the product type.
Compatible bridge parts supplied as a system
A complete crossing requires more than Bailey panels. Tuotian can supply matching transoms, bracing, steel decking, bearings, pins and other specified Bailey bridge components. Reviewing the parts as one supply package helps customers check the bill of materials, connection details and shipment quantities before production. Painted or hot-dip galvanized finishes can be specified according to the project’s exposure conditions and agreed technical requirements.
Manufacturing capacity with engineering support
Tuotian has an annual production capacity exceeding 60,000 tonnes across its product range. As a Type 321 Bailey Bridge manufacturer, the company supports customers from component selection and production through export delivery and installation guidance. Each proposal is reviewed against the relevant drawings, material requirements and project specifications. Bridge span and load capacity are confirmed through the design of the complete structure, rather than inferred from the panel model alone.
