1. Our manhole covers include ductile iron manhole cover and gray iron manhole cover, but we can also use other materials according to customer needs. 3. Ductile iron manhole cover adopts a retractable design to enhance the applicability of the manhole cover and can better adapt to the needs of different environments. 3. The surface treatment of ductile iron manhole cover is carried out through powder spraying, anodizing, electroplating, hot-dip galvanizing and other methods, thereby improving the corrosion resistance and aesthetics of the manhole cover.

Introduction of gray iron manhole cover:

Our gray iron manhole cover is made of advanced sand casting technology. As an important part of urban transportation and drainage systems, gray iron manhole cover shows excellent compression resistance and corrosion resistance during long-term use, and can cope with various environmental and load conditions. These gray iron manhole covers are widely used in many fields such as municipal infrastructure, drainage systems, urban roads, etc.
