What kind of wires are used in the cable trays of shopping malls

Wire mesh cable trays—often called basket trays —are constructed from welded steel wire, forming a lightweight open-grid structure. Unlike traditional formed trays, wire mesh trays rely on distributed wire intersections for strength rather than solid rails or rungs. There are several types of cable trays, including ladder, perforated, solid bottom, basket, and channel trays. Why Use It: Lightweight, easy to modify on-site, and ideal for low-voltage and data cables. A cable tray is a structural system used to support and manage electrical cables in various settings, such as industrial, commercial, and residential environments.
