Our engineer's guide helps you choose the right outdoor cable tray based on environment, load, and corrosion resistance. Select HDG, Aluminum, or FRP with confidence. A conservative choice blows the budget; an optimistic one guarantees premature failure. Cut through the guesswork with a systematic guide that aligns. From a scientific and mechanical perspective, cable tray types differ in three key areas: A ladder cable tray consists of two longitudinal side rails connected by transverse rungs, forming a structure similar to a ladder. The rungs are typically spaced at 6 in, 9 in, or 12 in intervals. Applications: Power plants and substations, Heavy. There are several types of cable trays, including ladder, perforated, solid bottom, basket, and channel trays. Each cable tray type performs a different function and comes in various materials such as aluminum, galvanized steel, and FRP. For outdoor use the trays must have extra protection, especially near saltwater bodies, to prevent corrosion and failure from exposure to the elements.
