Purchasing Guide

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

  • For procurement requirements that require the use of hot-dip galvanized cable trays, it is recommended to prioritize confirming the specifications such as width, height, and thickness of the trays to ensure that their load-bearing capacity matches the actual needs of the wiring project.
  • In highly corrosive environments such as industrial plants or data centers, the corrosion resistance of hot-dip galvanized cable trays is particularly critical, and technical indicators such as zinc layer thickness and uniformity need to be considered.
  • 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 ensure supply stability.
  • Hot dip galvanized cable trays are widely used in outdoor power distribution projects, and their protection level and durability performance need to be evaluated based on factors such as environmental humidity and temperature difference during procurement.

Knowledge Base

Q

1. The thickness of the zinc layer is an important indicator that determines the anti-corrosion performance of the bridge. Generally speaking, the thickness of hot-dip galvanized zinc layer should not be less than 65 micrometers (μ m), and high-quality products can even reach 85 μ m or thicker. The thicker the zinc layer, the stronger the corrosion resistance of the bridge and the longer its service life. When purchasing, be sure to check the product quality inspection report or third-party testing certification to confirm the zinc layer

Q

Hot dip galvanized cable tray is a rigid structural system made of cold-rolled steel plates, with a surface process of hot-dip galvanizing. It consists of straight sections, bends, tees, four-way components, as well as support arms (arm brackets), hangers, and other components in a trough, tray, or stepped manner, which provide close contact support for cables. Hot dip galvanized cable tray, also known as hot-dip galvanized cable tray, is a steel component that has been derusted and immersed in about 600
