Hydraulic flap gate features in hydraulic steel barrage: 1. The design is concise, without any complex transmission components. The gate section has no need for protection or repair, significantly improving the stability and reliability of the gate operation. Debris in the riverway is less likely to get stuck, and if it does, there is ample space to accommodate it, making it easy to clean up; 2. The structural steel flap gate has a solid water-blocking section without any joints.

The concrete structure gate is assembled from multiple precast components, hence the joints are prone to leakage; 2) The gate does not experience lateral movement, addressing the issue of lateral leakage. It can be replaced with the rubber stopper in place while the reservoir is filled, without affecting normal power generation; 3) When the gate is partially blocked by an object, it does not warp into an uneven shape, preventing inter-gate interference; due to the rigidity and high strength of the steel structure flip gate leaf.

Will not crack like reinforced concrete; even upon impact by heavy objects, it will only undergo localized deformation, which is easily repaired and does not require transportation channels, leading to low costs and rapid recovery.
