Purchasing Guide

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

  • For procurement requirements that require the use of linear drainage ditches, it is recommended to match different specifications of drainage capacity according to project scenarios (such as municipal roads, commercial plazas, or industrial plants), with a focus on parameters such as ditch width, load level, and material corrosion resistance.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and enterprises with industry data support or platform statistical information to ensure supply stability and engineering adaptability.
  • In high-frequency load scenarios such as airport runways or warehouse logistics areas, linear drainage ditches need to meet the requirements of high-strength concrete or polymer materials, while checking whether the technical parameters provided by the supplier meet the dynamic load-bearing standards.
  • It is recommended to compare the industry performance and product line coverage of different suppliers during procurement, and prioritize selecting enterprises with practical case support in the municipal or construction fields to reduce construction compatibility risks.
