There are two types of cast iron gates: square and round. Cast iron gates typically consist of a gate body and a frame, both made of cast iron. The gate leaf and frame are usually cast separately. The whole-body processed gate usually features a panel and reinforcing ribs structure, with the panel being either flat or arched. The gate body is usually cast and processed as a whole, but larger sizes can be divided into parts. Generally, a solid metal or bronze sealing strip is used as the support slider, and the bronze sealing strip is secured to the gate body with identical material沉头螺钉, with the screw head completing the sealing surface.

Cast iron gates offer excellent corrosion resistance. The installation process forms a one-time mold, resulting in lower maintenance costs compared to other gate types. Cast iron gates are generally used in combination with small screw actuators and other lifting and lowering machines. After long-term use, wear may occur, but we can adjust the water stop module to ensure the gate continues to operate normally. Compared to steel gates, cast iron gates have a simpler structure and can withstand greater water pressure. Due to their lower manufacturing costs, cast iron gates are suitable for smaller waterways. Steel gates, on the other hand, are larger in size and are only used in large waterways. The use of cast iron gates addresses issues such as heavy workload, high labor intensity, high costs, and poor water-sealing performance in the production of gates.
