This short shows key steps: cutting sheet metal to size, punching or slotting for wire access, bending edges to form the tray shape, welding joints for strength, and smoothing edges for safety. The process of manufacturing cable trays involves several critical steps, from selecting the right materials to the final product. Here's a breakdown of how it all works: 1. The material needs to be strong. The working principle follows a straightforward sequence: the steel coil is mounted on a decoiler, fed through a leveling and guide platform, then passed through the forming roller stations where the flat strip gradually takes the target profile shape. The machine is designed to roll-form a flat metal sheet into a specific shape and size required for cable tray production. The working principle of a cable.
