Description

This corrugated bridge is designed for temporary or light-duty permanent crossings over creeks, drainage ditches, farm paths, and forest roads. The corrugated bridge structure consists of hot-rolled or cold-formed corrugated steel plates bolted together to form an arch or circular section. The corrugation increases the shell's circumferential stiffness, allowing the bridge to withstand soil and live loads with relatively low self-weight. It is suitable for single-lane vehicle traffic or pedestrian paths, with a maximum allowable soil cover of 2 meters.
