Hydroelectric steel sluice gates are commonly used water control equipment in drainage projects, water conservancy, and hydroelectric power engineering, consisting of door frames, sluice plates, sealing rings, and adjustable wedge-shaped pressure blocks. Over time, as steel sluice gates wear, their sealing surfaces can be adjusted using the wedge-shaped pressure blocks to ensure proper operation. These steel gates are made from high-quality steel plates, employing rubber water stops and corrosion prevention measures, including sandblasting and thermal zinc spraying for surface treatment. Steel sluice gates feature reasonable and robust structures, excellent 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 made from super-durable, high-strength cold-rolled galvanized sheets, effectively preventing rust during construction and use, thereby extending the service life of the lightweight steel components. The structural lifespan can reach 30 years. They can be categorized based on their operational nature as:

Construction Gate: Steel gate for closing the diversion opening of the construction site

2. Work Gate: Adjusts flow through the guide flow orifice

3. Emergency Gate: A steel gate that can be opened or closed in case of accidents upstream or downstream.

4. Inspection Gate Closure: Close the water-blocking steel gate during equipment maintenance

By gate opening location

1. Open-top Gate: Top露出water surface

2. Submerged Sluice Gate: Top immersed below water level

Categorized by door leaf shape

Flat Steel Sluice Gate

2. Curved steel sluice gate

3. H-shape steel gate
