What Causes Cable Trays to Rust?

2025-11-24 01:37:04

As we all know, in today's era, cable trays are used to protect cables from external damage, so we need to pay special attention to the quality of the cable trays themselves. According to investigations, many customers find that the cable trays they purchased start to rust shortly after installation—some even rust within a few months. Could this be a quality issue with the cable trays? Below, the electrostatic Powder-coated cable tray manufacturer analyzes this problem from several perspectives:

1. Quality Issues with the Cable Tray's Raw Materials

This problem mostly occurs with products from small-scale cable tray manufacturers. Some customers choose to cooperate with third-tier manufacturers to save costs, and there is a reason why these manufacturers' products are cheap. Well-known manufacturers generally maintain reasonable product quality because they have established brands to uphold—thus, quality is inherently guaranteed. If a product is made of inferior raw materials, it is unlikely that the brand will have any reputation.

2. Environmental Issues at the Construction Site

What Causes Cable Trays to Rust?

When purchasing cable trays, some customers fail to assess the environmental conditions of the construction site. For example, if the construction site has extremely high corrosivity but ordinary Galvanized cable trays are used, the cause of rust is obvious. Therefore, we emphasize that when purchasing cable trays, you must first fully understand the construction site environment and then select the appropriate type of cable tray.

From our analysis, it is not difficult to see that the rusting of cable trays is closely related to product quality and the installation environment. To avoid this problem:

First, choose a reputable manufacturer that provides high-quality cable trays.

Pay attention to the on-site construction environment during installation.

Select the most suitable cable tray based on the specific environment.

The above is our analysis of the causes of cable tray rust. We hope this will be helpful to you after reading.
