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.
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.
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.
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.
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.
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.
| Parameter categories | Technical indicators | Remark |
| Product Name | Prefabricated Foot Bridges | Customized prefabricated pedestrian bridge |
| Structure Type | Truss (Pratt, Warren, Bowstring) / Beam | Truss or beam structure is available |
| Span Length | 10m – 60m (Clear Span) | Maximum span of single span without piers |
| Walkway Width | 1.5m – 4.0m | Net width can be customized according to traffic volume. |
| Material Standard | ASTM A572 Gr.50 / Q355B / Q420 | High-strength structural steel |
| Live Load | 85 psf (4.0 kN/m²) – 100 psf (5.0 kN/m²) | Meets the standards for dense pedestrian traffic |
| Vehicle Load | H-5 / H-10 Truck (Maintenance Vehicle) | Optional access for maintenance vehicles |
| Surface Finish | Hot-dip Galvanized / 3-Coat Epoxy Paint | Galvanized or three-layer epoxy zinc-rich paint |
| Decking Material | WPC / Treated Timber / Concrete / Steel Grating | Multiple bridge deck materials are available |
| Design Life | > 50 Years | Structural design life |
| Camber | Pre-cambered 1% – 2.5% | Pre-camber design to offset self-weight deformation |
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.
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.
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.
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.
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.
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.
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.
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.
