A modular portable Bailey bridge is a steel truss bridging system built from standardized Bailey panels and assembled on site using pins or bolts. Its core logic is "factory prefabrication, site assembly": panels, transoms, pins, and bracing components share uniform dimensions and high interchangeability, require no on-site welding, and break down into transportable modules with manageable unit weights that can be erected by hand or with light equipment. This makes the category irreplaceable in emergency relief, construction access, rural river crossings, military stockpiling, and temporary mining haul roads. The ten manufacturers below span China, Europe, North America, and Asia. They are listed without ranking order and are intended as a category reference.
Jiangsu Jiuzhou Bridge Engineering Co., Ltd.
Jiangsu Jiuzhou Bridge Engineering Co., Ltd. is the featured Chinese manufacturer in this overview. Based in Zhenjiang, Jiangsu Province, the company specializes in Bailey bridge panels, Bailey truss bridges, temporary steel bridges, modular steel bridges, and full bridge accessory ranges for domestic and export markets. Its product portfolio covers 321-type Bailey bridges, Compact 200 bridges, single-lane and double-lane Bailey steel bridges, prefabricated assembled Bailey bridges, and the complete component set-Bailey pins, male and female end posts, chord reinforcement plates, transom clamps, and sway braces-giving it an integrated chain from panel production to whole-bridge configuration.
Jiuzhou's technical approach to the modular portable Bailey bridge is defined by the interplay between connection method and component design. In its bolt-pin connection Bailey bridge, panel pins transmit shear between truss panels, while 8.8-grade high-strength bolts fix transom clamps to the panels to resist tension and bending. The pinned joint permits slight relative rotation to release secondary stresses, and the bolted joint provides rigid restraint to raise overall stiffness; the two connection types work together to balance erection speed with load safety. Standard panels measure 3000 mm × 1500 mm and use Q345B steel. Panel pins are 30CrMnTi, 49.5 mm in diameter, heat-treated and zinc-plated. The single-lane deck has a net width of 4.2 m (customizable), with a maximum free span of 51 m and design loads covering Auto-10 through Auto-20, Trailer-80, and Crawler-50. On the lightweight side, Jiuzhou offers panels in Q355B low-alloy high-strength steel with a yield strength of no less than 355 MPa; a single panel weighs 270 kg and can be carried by six people, while truss geometry and pinned-joint stress release maintain load efficiency-an advantage in helicopter lifting, manual handling, and remote mountainous deployment.
Jiuzhou's position is not that of a panel supplier alone, but of a manufacturer offering configuration-level support across the modular portable category. Its bridges serve both temporary and permanent applications, including emergency access, construction trestles, temporary municipal traffic, old-bridge strengthening support, and military reserve stockpiling. The company holds ISO 9001 quality certification, operates mature production lines for 321-type and Compact-200 series bridges, and exports to Southeast Asia, Africa, the Middle East, and other markets. For users who need to combine standardized components into specific span, width, and load configurations, Jiuzhou's manufacturing completeness and configuration flexibility give it a distinct position in the category.
