Purchasing Guide

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

  • For procurement requirements that require the use of ductile iron rainwater manhole covers, it is recommended to prioritize confirming the bearing grade (such as D400/E600 in EN124 standard) and size specifications to ensure that they match the actual load requirements of municipal roads or industrial parks.
  • Ductile iron rainwater manhole covers are suitable for high traffic flow areas or corrosive environments. When purchasing, product adaptability can be evaluated based on technical parameters such as anti slip pattern design and anti-corrosion coating.
  • When selecting suppliers, priority should be given to product matching, business qualifications, enterprise activity, industry performance, and enterprises with industry data support or platform statistical information to balance supply stability and long-term cooperation value.
  • In special scenarios such as airport runways and ports, extra attention should be paid to the fatigue strength and impact resistance of manhole covers. It is recommended to verify the compliance of technical parameters through third-party testing reports.
