A cable tray is a structural system used to securely support and route cables, typically in commercial or industrial settings. It provides a safe pathway for electrical wires, data cables, and communication lines while maintaining easy access for future upgrades or maintenance. Common types include ladder trays, solid-bottom trays, and perforated trays, made from materials such as steel, aluminum, or fiberglass. Cable trays are often used in large-scale projects like data centers, factories, and power plants due to their durability, ease of installation, and ability to accommodate a variety of cable sizes and configurations.
