Steel gates are commonly used water control and stoppage equipment in drainage, hydraulic, and hydroelectric projects, consisting of door frames, gate plates, sealing rings, and adjustable wedges. Over time, as steel gates wear, their sealing surfaces can be adjusted with wedges to ensure normal operation. Steel gates are made from steel plates, with rubber waterstops and corrosion prevention methods applied to the surface, which includes sandblasting for rust removal and hot galvanizing. These gates feature rational and sturdy structures, high wear and corrosion resistance, reliable performance, and are easy to install, adjust, use, and maintain. Durability: The light steel structure is composed entirely of cold-formed thin-walled steel components, with the steel bones made from super corrosion-resistant high-strength cold-rolled galvanized plates. This effectively avoids the effects of rust on the steel plates during construction and use, thereby extending the service life of the light steel components. The structural lifespan can reach 30 years.
