Common cable trays are made of galvanized,, aluminum, or glass-fiber reinforced plastic. The material for a given application is chosen based on where it will be used. Galvanized tray may be made of pre-galvanized steel sheet fabricated into tray, or may be hot-dip galvanized after fabrication. When galvanized tray is cut to length in the field, usually the cut surface will be painted with a zinc-rich compound to protect the metal from corrosion.

Cable trays themselves are not conductive, but their surface dampness can have a detrimental effect on the insulation of cables they carry. Moisture can create a conductive water film on the surface of the trays, initiating electrochemical corrosion, especially if the material contains reactive metals. Cable tray wiring systems are more desirable than conduit wiring systems where moisture is a problem. Conduit wiring systems require careful attention to many details to prevent the moisture in the conduits from getting into the electrical equipment enclosures. Conduits breathe, they draw in. If you're wondering how to stop water and dust from wrecking your cable installations, or how to choose trays that genuinely stand up to the elements, you're in the right place. All illustrations, descriptions and technical information included in this document are provided as indications and can cable trays are equivalent.
