Purchasing Guide

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

  • When choosing the supply of cover plates and trench covers, it is recommended that enterprises match the actual application scenarios based on key technical parameters such as load-bearing grade and material type (such as cast iron, composite materials). For example, municipal roads need to focus on compressive strength, while industrial parks need to consider corrosion resistance.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and companies with industry data support. Such suppliers can usually provide more stable delivery capabilities for cover and groove cover products.
  • For different usage scenarios such as drainage systems or cable trenches, the size specifications of cover plates and trench covers (such as wellhead diameter and gap width) should strictly correspond to the on-site construction requirements to avoid installation adaptation issues in the later stage.
  • In areas with high-frequency traffic in industrial plants, it is recommended to purchase trench cover products with anti slip patterns or reinforced rib designs. Such detailed designs can effectively extend the service life and reduce maintenance costs.
