Steel Composite Gate

The steel composite gate is a new type of hydraulic metal structure equipment that combines the advantages of steel gates and cast iron gates, featuring high strength, convenient installation, and excellent water-sealing performance.
Structural Features
The steel composite gate consists of a gate leaf welded from Q235 or 16Mn medium plate and a cast iron gate frame. The water-sealing surface is precision-machined with H62 brass or stainless steel to ensure sealing performance. The surface of the gate leaf is treated for corrosion protection according to the SL105 standard, making installation simple and eliminating the need for frequent replacement of water-sealing rubber.
Advantages
High Strength: The combination of a steel frame and cast iron water-sealing surface makes it suitable for large-span and high-head scenarios.
Low Maintenance Cost: Simplified installation process reduces daily maintenance, particularly avoiding the hassle of frequent water-sealing rubber replacement.
Wide Applicability: Suitable for water conservancy, hydropower, water supply and drainage projects, and environmental protection fields, such as pump station water diversion and river regulation.
