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.
Material:
Q235B Steel (Chinese standard steel), Stainless steel 304, SS316 & SS316L
Surface Finish of Perforated Channel Trays:
Electro zinc plated steel cable trays for indoor use to BS EN 12329-2000, 12microns thick;
Powder coated carbon steel perforated trays for indoor use to JG/T3045-1998, between 6 and 10 microns thick;
