Steel gates are commonly used water control and stopping equipment in drainage and water conservancy projects, hydropower engineering, and are composed of components such as door frames, gate plates, sealing rings, and adjustable楔块. After long-term use and wear, the sealing surface of the steel gate can be ensured for normal operation by adjusting the楔块. Steel gates are made of steel plates as the base material, with rubber water stops and corrosion prevention measures applied, and are surface treated with shot blasting to remove rust and hot galvanized for added durability. They feature rational and sturdy structure, high wear and corrosion resistance, reliable performance, and ease of installation, adjustment, use, and maintenance. Durability: The lightweight steel structure is entirely composed of cold-formed thin-walled steel components, with the steel frame made from super corrosion-resistant high-strength cold-rolled galvanized steel plates, effectively avoiding the impact of rust on the steel plates during construction and use, thereby increasing the service life of the lightweight steel components.

After planing, the surface is flat, smooth, and tightly fitted, merging the joint face, stopper water surface, and sliding track into one. Under the action of the opening and closing machine, as the gate operates, the tightly closed iron angle and gate frame sliding track ensure the longitudinal and transverse movement of the gate. With the combined forces of water pressure and the tightly closed iron angle, the gate moves smoothly, ensuring a tight fit between the gate and the sliding track of the gate frame, thereby effectively preventing water leakage.

Gates are divided into two main categories based on the shape of the gate leaf: PZ flat gates and PGZ arch gates. The specific type to be chosen can be determined through a comprehensive comparison of factors such as the gate opening size, water head pressure, opening and closing type, and the gate's own weight.

Gates are divided into two main categories based on the combination of the gate plate structure: integral and assembled. Small-sized gates are generally made in an integral style, but gates at construction sites with poor mechanical transportation conditions can also be assembled for easier manual transport. Gates of medium size and above are usually made in an assembled style.
