Steel gates are commonly used in water supply and drainage projects, water conservancy, and hydropower projects for water control and stoppage. They consist of door frames, gate plates, sealing rings, and adjustable wedge-shaped pressure blocks. After long-term use and wear, the sealing surface of the steel gate can be adjusted with the wedge-shaped pressure blocks to ensure normal operation. Steel gates are made from steel plates, with rubber waterstops and corrosion prevention applied. The surface is treated with sandblasting to remove rust and hot galvanized for added protection. Steel gates feature a rational and sturdy structure, high 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 the steel frame manufactured from super corrosion-resistant high-strength cold-rolled galvanized sheets. This effectively prevents rust from affecting the steel plates during construction and use, thereby extending the service life of the lightweight steel components. The structural lifespan can reach 30 years.
