Purchasing Guide

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

  • For procurement requirements that require the use of fire-resistant trough type cable trays, it is recommended to prioritize checking parameters such as fire resistance duration, trough thickness, and bearing capacity to ensure compatibility with building fire protection levels or industrial environmental requirements.
  • In high temperature and high-risk scenarios such as chemical and power industries, fire-resistant trough type cable trays need to have flame-retardant coatings and structural stability, while paying attention to the sealing of trough covers to prevent dust intrusion.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and companies with industry data support to ensure supply stability and compliance.
  • When deploying fire-resistant trough type cable trays in high-rise buildings or underground pipe galleries, it is recommended to combine the width and bending radius parameters of the trough frame to adapt to complex wiring spaces and meet fire zoning requirements.
