Establishing partnerships. The cable tray production line is an intelligent mechanical integrated system designed for the production of cable tray systems, which realizes the precise forming of the bridge structure through automated processes. It begins with raw material input, usually galvanized steel or stainless steel coils. These coils are then uncoiled and flattened through a leveling machine. Next, the material is slit to the required width for the tray. association representing the major electrical equipment manufac-turers in the U.
