Prefabricated Foot Bridges characteristics
Speed field installation
The factory pre-assembly process is adopted, and only bolting or integral lifting is required on site. The main beam erection can usually be completed within 1 working day, which reduces 80% of the field operation time compared to the cast-in-place construction and greatly reduces the labor cost.
High-precision structure ensures stability
Based on BIM modeling and CNC laser cutting manufacturing, the structural dimensional tolerance is controlled within ± 2mm. The precise node connection eliminates the internal stress generated by the forced assembly on site and ensures the long-term stability of the bridge structure.
Excellent anti-corrosion reduces operation and maintenance costs
Available in hot-dip galvanized (ASTM A123) or weathering steel options. In the C4 corrosive environment, the thickness of the anti-corrosion coating can reach 120 μm, which can achieve maintenance-free for more than 20 years and reduce the operation and maintenance cost of the whole life cycle.
High strength to reduce load
Using high-strength low-alloy steel (such as ASTM A572 Gr.50), under the premise of ensuring a live load capacity of 5.0 kN/m, the dead weight is 60% lighter than that of concrete bridges with the same span, thus reducing the requirements for foundation bearing capacity and the tonnage of hoisting equipment.
Diversified bridge deck system
Compatible with a variety of deck pavement materials, including IPE hardwood, anti-slip patterned steel plate or FRP grating. The bridge deck system has been tested for anti-skid coefficient (friction coefficient> 0.5) to ensure the safety of pedestrians in rain and snow.
Compliance with international design codes
The structural design strictly follows the AASHTO LRFD footbridge design guide or Eurocode 3 standard. The wind resistance can reach 120 km/h and the seismic fortification intensity can reach 8 degrees, which is suitable for various extreme climate areas.

Prefabricated Foot Bridges contrast points
Compared with the traditional on-site concrete footbridge, this Prefabricated Foot Bridges takes advantage of industrial manufacturing to significantly improve engineering efficiency and quality control capabilities. The following are specific solutions for traditional construction pain points:
Avoid traffic paralysis caused by long-term road closures
Traditional bridge construction often requires scaffolding and road closures for weeks or even months. The prefabricated pedestrian bridge adopts the integral hoisting technology, and only needs to carry out traffic control during the off-peak hours (such as 4 hours at night) on the day of hoisting, so as to minimize the interference to the surrounding road traffic and commercial operation.
Eliminate hidden welding quality hazards outside the controlled environment
On-site welding is extremely susceptible to wind, humidity and the technical level of workers, resulting in pores or cracks in the weld. All key welds of this product are completed by certified welders under the constant temperature environment of the factory, and undergo 100% ultrasonic flaw detection (UT), which completely eliminates the hidden danger of structural safety caused by outdoor operation.
Solve the problem of uncontrollable construction period in severe climate
Traditional construction is seriously affected by rain, snow and freezing weather, which often leads to unlimited delay of construction period. Fabrication of prefabricated bridges is carried out in an indoor factory in parallel with foundation construction, without weather restrictions. Once the foundation is ready, it can be shipped and installed immediately, ensuring that the project is delivered on time and avoiding the risk of default.

Municipal Planning and Public Works Department
Applicable to urban parks, greenway links and pedestrian bridge projects across busy streets. The rapid deployment capability of prefabricated bridges helps government departments to improve the city's slow traffic system in a short period of time and improve citizen satisfaction.
Commercial real estate and park developers
It is suitable for connecting office buildings, shopping centers or campus buildings. Flexible exterior design (such as curved trusses, custom colors) can be perfectly integrated with modern architectural styles to enhance the overall commercial value of real estate projects.
Owners of golf courses and resorts
It is suitable for landscape bridges crossing water obstacles or topographic undulations. The lightweight design allows the use of small equipment on sensitive turf construction, and the anti-slip and quiet bridge design can accommodate the smooth passage of golf carts.
Industrial and mining infrastructure purchasers
Suitable for access roads across conveyor belts, pipelines or railways. Prefabricated steel bridges with high anti-corrosion grade can adapt to the highly corrosive environment of chemical plants or mining areas, and provide safe crossing channels for workers.
Prefabricated foot Bridges instructions
Foundation embedment and check
Concrete abutments shall be poured according to the drawings and anchor bolts shall be accurately embedded. Before the arrival of the bridge, the total station must be used to review the span and bolt position, and the error shall be controlled within ± 3mm.
Unloading and ground assembly
After arriving at the site in sections, the bridge shall be unloaded to the level ground by crane. For extra-long span bridges, splice in sections on the ground, tighten the high-strength bolts to the design torque value, and repaint the splice.
Hoisting in place
Establish the lifting point according to the calculated position of the center of gravity, and use the special lifting tool for trial lifting. Hoist the bridge above the abutment as a whole, and slowly drop it to align with the embedded bolts. During the process, use cable wind ropes to control the attitude of the bridge body.
Fixing and auxiliary installation
Tighten the anchor bolts and double nuts after dropping. Finally, install handrails, railing nets and bridge deck pavement, clean up the site and carry out the final load and safety inspection.

FAQ And Contact Us
Welcome to our Frequently Asked Questions page. We have compiled answers to common questions you may have, hoping to provide you with clear and quick solutions. If you cannot find the information you need here, please feel free to contact our customer support team.
Q1: What is the maximum span of a Prefabricated foot bridges that can be achieved without the need for intermediate piers?
A: Depending on the truss height and width, usually steel truss structures can achieve a single-span net span of 40 meters to 60 meters. If it exceeds this length, it is recommended to add intermediate piers or adopt a suspension/cable-stayed structure to ensure economy.
Q2: How long is the production cycle of prefabricated footbridges?
A: The production cycle of standard design is usually 6-8 weeks. This includes the time to deepen the approval of design drawings, material procurement, factory manufacturing and anti-corrosion treatment. Complex projects with a high degree of customization can take 10-12 weeks.
Q3: How can this bridge be transported to the construction site?
A: Bridges are usually manufactured in sections, and the length of each section is controlled at 12-18 meters to adapt to standard flatbed trailer transportation. Extra-wide bridges (width> 3.5 m) may require a special transport permit or be designed for site assembly in longitudinal sections.
Q4: What kind of maintenance is required for steel prefabricated bridges?
A: Hot-dip galvanized bridges are basically maintenance-free. If it is a paint coating, it is recommended to conduct a visual inspection once a year, and partial repainting may be required every 10-15 years. Wooden bridge decks may need to be cleaned and oiled every 3-5 years.
Q5: What load standards do your products meet?
A: Our design defaults to AASHTO LRFD Guide Specifications for the Design of Pedestrian Bridges (USA) or Eurocode 3 (Europe) standards with a standard population live load of 4.0-5.0 kPa.
Q6: Can the bridge carry light vehicles?
A: Yes. The sill design can be enhanced as required to carry H-5 (5 tons) or H-10 (10 tons) emergency vehicles, ambulances or golf carts, but this needs to be explained in advance during the design phase.
Please feel free to contact us. We look forward to hearing from you.
