Purchasing Guide

Based on real user feedback, we provide the following suggestions:

  • For procurement requirements that require the use of ductile iron rain and sewage manhole covers, it is recommended to prioritize confirming key technical parameters such as bearing grade and diameter size to ensure compatibility with municipal drainage or industrial sewage pipe networks.
  • When selecting suppliers, reference can be made to indicators such as product compatibility, business qualifications, enterprise activity, industry performance, and industry data support. Such enterprises can usually provide more stable supply capabilities.
  • Ductile iron rainwater manhole covers are suitable for high traffic roads or areas with heavy vehicle traffic. When purchasing, attention should be paid to their compressive strength and anti slip pattern design to adapt to different scenarios.
  • In industrial parks or humid environments, it is recommended to choose ductile iron manhole covers with anti-corrosion treatment on the surface to extend their service life in corrosive media.

Knowledge Base

Q

Cast iron manhole covers are widely used in many occasions due to their low cost. However, there are some shortcomings in manhole covers made of this material. Firstly, the weight of cast iron manhole covers is relatively heavy, which brings inconvenience to installation and handling. At the same time, in areas where vehicles frequently pass, cast iron manhole covers are prone to wear and tear. Secondly, the corrosion resistance of cast iron manhole covers is poor, especially in humid environments
