Engineered specifically for SJ-200 and SJ-321 modular steel bridge frameworks.
Manufactured from premium Q355B and Q235B high-strength structural steel.
Comprehensive customization available, backed by free structural calculations.
Sourced directly from the manufacturer with full ISO9001 and CE compliance.
The structural integrity of any modular bridge system relies heavily on the foundational strength of its transverse components. The Horizontal Support Beam for Bailey Bridge Construction acts as the critical load-bearing spine, expertly designed to absorb, distribute, and mitigate immense dynamic forces generated by heavy vehicular traffic and adverse environmental conditions. When you run your hand along the cold, unyielding surface of the beam, the flawless hot-dip galvanized finish offers a tactile confirmation of its resilience against harsh, corrosive environments. The precision-engineered connection points ensure a flush, secure fit during assembly, eliminating the metallic rattling and micro-vibrations that often plague inferior structural elements under heavy loads. The distinct, solid resonance of this high-grade steel during installation assures construction teams of its immense structural density and uncompromising build quality.
By integrating these robust beams into your infrastructure projects, engineering teams can drastically reduce structural deflection and torsional stress. This translates directly to enhanced safety margins and a significantly extended operational lifespan for the entire bridge assembly. Whether deployed over a rushing river, spanning a rugged mountain gorge, or serving as a temporary military crossing, the beam's superior shear resistance guarantees that the bridge decking remains perfectly aligned and stable. Contractors and project managers will appreciate the meticulous craftsmanship that goes into every unit, transforming complex erection schedules into streamlined, predictable operations. The inherent reliability of this support beam minimizes future maintenance requirements, ensuring that your infrastructure investments remain sound, secure, and fully operational for decades to come.

Achieving structural equilibrium in modular bridge construction requires components that are not only robust but also meticulously engineered for seamless integration. Our Horizontal Support Beams are designed to elevate the efficiency and safety of your entire project.
Optimized Load Distribution: Engineered to channel vertical and lateral forces evenly across the Bailey bridge panels, preventing localized stress fractures and ensuring uniform weight bearing under heavy traffic.
Precision Machined Joints: Every connection point is cut and drilled with exacting tolerances, allowing pins and bolts to slide into place smoothly without the need for aggressive on-site modifications or forceful hammering.
Adaptive Tolerance: Designed to accommodate the natural thermal expansion and contraction of steel structures, maintaining bridge geometry and deck flatness across extreme temperature fluctuations.
Rapid Deployment Capability: The standardized dimensions and intuitive connection interfaces empower construction crews to accelerate the erection process, making it highly suitable for time-sensitive emergency response scenarios.
Installation Method Recommendation
The foundation of any enduring bridge structure lies in its metallurgy. We utilize premium Q355B and Q235B high-strength structural steel, renowned for its exceptional shear resistance and tensile strength. To combat the relentless degradation caused by moisture, salt, and industrial pollutants, each beam undergoes a rigorous surface treatment process. Whether you opt for hot-dip galvanizing or an epoxy zinc-rich primer coating, the result is an impenetrable anti-corrosion barrier. This ensures that the beams can withstand the most extreme outdoor environments and over-water applications, safeguarding the bridge's long-term safety and vastly extending its service life.
Time is a critical metric in infrastructure development. Our products feature a highly standardized, modular design that guarantees perfect interchangeability among components. We empower your construction teams by providing comprehensive installation drawings, detailed operational manuals, and step-by-step construction videos, supplemented by remote or on-site expert guidance. This modularity facilitates advanced erection techniques, such as the cantilever launching method or crane-assisted assembly, which drastically reduces the complexity of the build. The result is a significantly shortened project timeline and a substantial reduction in manual labor costs.
No two topographies or project requirements are identical. To address this, we maintain an in-house team of seasoned structural engineers dedicated to providing free, comprehensive bridge structure calculations and detailed CAD drawing services. Whether your project utilizes the SJ-200 or the SJ-321 framework, we deliver precise, non-standard customizations. We meticulously tailor the span lengths and load-bearing capacities to meet specific regulatory demands, including HL93, HS20-44, and heavy-duty MLC110 military load classifications, ensuring an exact fit for your unique terrain and traffic requirements.
Procuring directly from the source manufacturer guarantees uncompromising quality oversight. Our enterprise operates under strict adherence to ISO9001, ISO14001, and ISO45001 management system certifications. Every horizontal support beam is manufactured to meet or exceed rigorous international standards, including GB, ASTM, and CE specifications. To provide complete peace of mind and ensure regulatory compliance, every shipment is accompanied by exhaustive documentation, including raw material certificates, independent test reports, and factory quality certificates. You can trust that every beam meets the highest echelons of engineering safety.
The environmental adaptability of our horizontal support beams and Bailey bridge components is unmatched. Their robust design allows for seamless integration into a vast array of infrastructural scenarios. They are frequently deployed as the structural backbone for permanent highway bridges, pedestrian footbridges, railway crossings, and elevated viaduct supports. Furthermore, their rapid-assembly characteristics make them the premier choice for temporary or semi-permanent emergency access routes during flood relief operations, disaster recovery, and tactical military exercises.

First of all, an experienced construction team should be assigned to undertake the erection of the bridge. We have studied the drawings of the erection site and surrounding area, and conclude that the installation site is spacious and flat, so we recommend the installation procedure as follows:
1. Assemble the bilateral bailey panels to two whole construction, including the lower chord reinforced、horizontal bracing、vertical bracing、male and female end post. every assembling unit is mainly composed by 27 pieces of bailey panel. Meanwhile, the bridge bearings are installed on the abutment. note that：check the length of the single whole bailey truss and the distance between the bolts of the two side of the river, if not fit , adjust the bolts.
2. Use suitable lorry-mounted crane to lift the two assembling truss unit and place them on the two side abutments. the single combined truss unit is weight about 11tons and 27.4 m length.
3. Install the transom, please refer the video. for the weight of one piece of transom is about not more than 1 ton，so it need a small crane. In order to increase the stability of the structure during the erection, the nearest transom and the farthest transom, as far as possible according to the capacity of the crane, should be installed first, then for other transoms between them.
4. Install the sway bracing，then pave the first row in width direction of bridge decking on the transoms, including the side and middle bridge decking. Meanwhile, install the upper chord reinforced to strengthen the structure, then the crane could move onto the bridge decking to install the following ahead transoms, similar ways like upper procedure to be perform.
5. The rest can be done in the same manner.
6. Final, install the upper chord reinforced、curb、gap plate、handrail、 connective plate and handrail column.
