Q355/Q420 high-strength steel structure

Excellent Economy for Large Spans: Adopting Q355/Q420 high-strength steel and relying on the axial force-bearing system of the truss structure, it achieves efficient utilization of material strength. The self-weight of the structure is reduced by more than 30% compared with traditional concrete beam bridges, and it can meet the span requirements of 20m-50m (e.g., scenarios such as river-crossing and main road-crossing). 

There is no need to additionally increase the cross-sectional size and material cost, making it suitable for multi-field projects such as municipal engineering and highway construction.

Strong Controllability of Building Height: The main truss adopts a tie rod-compression rod combined system, and the structural height is controlled by the crossbeam. For products with a 30m span, the building height can be controlled within 1.2m-1.5m, which is 40% lower than that of prestressed concrete beam bridges with the same span. 

It can meet the requirements of under-bridge clear height limits (e.g., for the passage of heavy vehicles and avoiding obstruction by surrounding buildings) and can be customized and optimized according to project parameters to avoid design rework.
