Steel gates are commonly used for water supply and drainage projects, hydraulic and hydroelectric projects as water stop and damming equipment, composed of door frames, gate plates, sealing rings, and adjustable wedge-type pressure blocks. Over time, after prolonged use, the sealing surface of the steel gate can be adjusted using the wedge blocks to ensure normal operation. The steel gates are made from high-quality steel plates, with rubber water stoppers and anti-corrosion methods applied on the surface for sandblasting to remove rust and thermal zinc spray. Steel gates feature rational and sturdy structures, excellent wear and corrosion resistance, reliable performance, and are easy to install, adjust, use, and maintain. Durability: The lightweight steel structure is entirely composed of cold-formed thin-walled steel components, with steel bones made from super anti-corrosion high-strength cold-rolled galvanized plates, effectively preventing 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.
