Steel dams, also known as hydraulic steel dams or landscape steel dams, are commonly found in the management of municipal rivers. Made of steel, these dams possess all the characteristics of steel products. They excel in performance, effectively reducing water flow speed and also beautifying the cityscape. They provide protection for the public's daily life and property.

The hydraulic steel sluice gate utilizes a hydraulic propulsion system. Typically, when the upstream water level is low, the propulsion force keeps the steel gate upright, effectively retaining water to ensure water supply for local residents. As the upstream water level rises, the pressure and impact force cause the hydraulic steel sluice gate to tilt, releasing excess water into the downstream. Additionally, the layered hydraulic protection system of the steel sluice gates continually reduces the impact force of the water flow, thereby slowing the water velocity. This is further complemented by the use of steel gates to effectively manage water resources. Even in the case of extensive floodwater discharge, it provides ample time for the public to relocate or temporarily avoid risks.
