Cable tray systems range from easy to highly customized, so it is best if you understand what your application requires before starting shopping. This is a quick rundown of some basic tray styles and what they work most effectively for...
Basket-Style Cable Trays

Basket trays might be mounted along walls, suspended in the ceiling, as well as run below raised flooring that's often within data centers and also other facilities. Their "open" structure allows air to only flow through and makes sure that cables stay well-ventilated and cool, preventing heat-related malfunctions. Typically, they're made from steel, and come in different finishes, including powder coat and zinc plating.
Solid PVC Cable Routing Systems
Fashioned with bend-sensitive fiber optic cabling in mind, the defining top features of PVC trays are their solid floor and side walls.

Fiberglass cable trays are totally non-conductive, so they really won't need to be grounded in order to meet electrical codes. They're lightweight, strong, won't obstruct signals, and they are quite often more proof against UV, corrosion and chemicals than comparable metal trays.
Snake Trays
