Perforated Cable Tray

Perforated metal channels are commonly fabricated into Cable Trays (Channel Trays, Ladder Trays and Bridge Trays) for cable wiring protection. Perforated Channel Cable Tray has rectangular or round hole commonly punched inside the sheet body to allow air flow. This is a rigid solid slotted metal support for wire cables and optical fibers providing good covering for the telecommunication lines. Hengda can supply channel trays in stainless steel or carbon steel with various hole patterns and sizes. A wide range of perforated cable trays can be made for customers specific requirements.
