1- Cable Trays
Contructed from single sheet of perforated metal.They are convenient for cables
which require both a degree of protection from external damage and some
ventilation.
2- Cable Ladders
Straight sections of ladder type cable trays consist of two longitudinal side rails,
connected by individual transverse members, or rungs, which are welded to
the side rails or bolted in case of GI trays. This type of cable tray provides maximum ventilation to heat producing cable such as power cables.

Straight sections of solid bottom cable trays contructed from single sheet
of metal, providing excellent protection from external damage. They are
used primarily for intrumantal control, communication and other non-heat
producing cables.
