Cast iron gates are generally equipped with adjustable wedging devices, and wedging pairs (such as wedges and wedges, wedges and eccentric pins, etc.) are respectively installed on the door body and door frame. Adjusting the wedge tightening device can make the gate body tightly adhere to the door frame when it is closed, achieving the water stop requirement.

Cast iron gates are usually equipped with manual or electric screw type hoists for operating the gate's opening and closing.

Cast iron gates have the following characteristics:

Simple layout, compact structure, and space saving; The operation and maintenance are simple, reducing operating costs, but the cost of cast iron gates is slightly higher than that of steel gates.

Strong corrosion resistance. The material of the door body and frame is cast iron, and the water stop surface is embedded with corrosion-resistant materials such as copper alloy or stainless steel, which has strong anti-corrosion ability and is particularly suitable for sewage or seawater environments. In places with special requirements, materials with stronger corrosion resistance such as nickel chromium alloy cast iron can also be used.

The water stop pair of cast iron gate is processed as a whole, with good water stop effect and long service life of metal water stop.
