Ductile iron cover plate
The difference between load-bearing and heavy-duty is actually the process of the cover plate. The load-bearing capacity mainly refers to the design of reinforcing ribs and other methods in the production process in order to meet the main parameter requirements and reduce the weight and volume of the main structure. The heavy-duty type mainly relies on the material index of ductile iron to meet the usage parameter requirements. The simplest explanation is mechanical optimization.
