A cable tray (or simply cable tray) is a rigid structural system that provides close support for cables, consisting of straight sections, bends, tees, and crosses in trough, tray, or ladder configurations, as well as brackets (arm-type supports) and hangers.
Cable trays are classified into trough, tray, ladder, and mesh structures, and consist of supports, brackets, and installation accessories. Cable trays within buildings can be installed independently or laid on various building structures and pipe rack supports. They should feature simple structure, aesthetically pleasing appearance, flexible configuration, and convenient maintenance. All parts must be galvanized before installation on exposed exterior sections of buildings.
