In general, a cable tray is to support a structure that receives a large load in an industrial field of various fields such as various pipes including gas pipes, water pipes, and various cables including optical cables. .

With the recent development of the optical cable industry, a new optical cable construction method has been proposed using cable trays for new apartments or single-family homes. Although parallel laying method was used, piping and optical cable laying using cable trays is continuously increasing in new apartments, factories, ships and existing houses to minimize cable exposure.

Currently, cable trays are largely classified into prefabricated trays and welded trays. Prefabricated trays support low loads such as wiring and cables in single houses, small factories and buildings, while welded trays are used in ships, structures, factories, and apartments. Support structures that are subject to heavy loads such as water pipes in electrical wiring and buildings.
