Steel gates are commonly used in water supply and drainage projects, water conservancy, and hydropower projects as water control and stoppage equipment, consisting of components such as door frames, gate plates, sealing rings, and adjustable wedged pressure blocks. Over time, as steel gates wear, their sealing surfaces can be adjusted using the wedged pressure blocks to ensure proper operation. Steel gates are made from steel plates, with rubber water stops and corrosion prevention methods applied to the surface, which includes sandblasting for rust removal and hot galvanized coating. These gates feature reasonable and sturdy structures, strong wear and corrosion resistance, reliable performance, and ease of installation, adjustment, operation, and maintenance. Durability: The lightweight steel structure is composed entirely of cold-formed thin-walled steel components, with steel bones manufactured from super corrosion-resistant high-strength cold-rolled galvanized plates, effectively preventing rust during construction and use, thereby extending the service life of the lightweight steel components. The structural lifespan can reach 30 years.
