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

The concrete structure sluice gate is assembled from multiple prefabricated components, making the joints prone to leakage; 3. The sluice gate does not allow for lateral movement, addressing the issue of lateral leakage. When the lateral water stop rubber is damaged by debris, it can be replaced while the reservoir is filled, without affecting normal power generation; 4. The sluice gate does not deform unevenly when a single object is jammed on one side, thus preventing mutual interference between the gates; Due to the rigid and high-strength characteristics of the steel structure flip gate leaf.

Not as prone to cracking as reinforced concrete, it only experiences localized deformation upon impact from heavy objects, requiring minimal repairs and no transportation channel fees, with a quick recovery speed.
