we have ductile iron covers of different model, light or heavy,singleor double, they can be of different diameters, different weights and different withstand gravity ,we can also make to-order productions.

Many of the engineering properties of steel can be realized with Ductile Iron Casting. It has the ability to be cast in heavier sections and can be used to produce larger castings than malleable iron. Ductile Iron Casting has replaced forgings, weldments and steel castings in an ever increasing number of applications.Ductile Iron Casting is particularly well suited for:

Valves Pump - Gears and Rollers Spring Hangers Suspension Parts Wheel Hubs Ductile Iron Castings
Custom Ductile Iron Castings Bearing Caps Hardware Universal Joints Threadless Connectors and Flanges Various Automotive and Agricultural Items. Advantages of Ductile Iron Casting:Ductile Iron Casting provides Higher Tensile Strength Less Deflection Under Load Conditions No Straightening Required in Most Instances No Problems With Hot Tears and Cracks Good Machinability Easier Feeding of Difficult Designs
