Guia de compra

Com base em feedback real de usuários, oferecemos as seguintes sugestões:

  • For procurement requirements that require the use of fire-resistant trough boxes, it is recommended to prioritize confirming key technical parameters such as fire resistance rating, trough material, and load-bearing capacity to ensure compliance with the actual requirements for fire protection of building electrical circuits.
  • In high-risk scenarios such as petrochemicals or data centers, fireproof trough boxes need to have corrosion resistance and impact resistance characteristics, and different specifications of partition designs should be selected according to cable density.
  • 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 procurement risks and long-term cooperation stability.
  • For the application of enclosed spaces such as underground pipe galleries, it is recommended to purchase fireproof trough boxes with moisture-proof sealing functions and verify the actual case data of similar projects from suppliers.
