1, steel structure gate, steel structure gate takes steel plate as base material, adopts rubber to stop water, and can be sandblasted and anticorrosive with metallic paint on the gate surface.
2. Cast iron gates are used in municipal, petroleum, chemical, power station, metallurgy, coal, light industry, food, water conservancy, sewage treatment and other water supply and drainage projects.
3. Ductile iron gate, the valve body adopts ductile iron, which improves the plasticity and toughness, thus obtaining higher strength than carbon steel.
