With the continuous development of my country's construction industry, the proportion of domestic cable trays is constantly increasing. There are many types of cable trays, and the most commonly used is the stepped cable tray. This kind of bridge is very convenient to stretch, easy to use, and has good heat dissipation and air permeability.

There are many types of cable trays, and the most commonly used is the stepped cable tray. This kind of bridge is very convenient to stretch, easy to use, and has good heat dissipation and air permeability. It is especially suitable for the laying of large cables, and high-voltage and low-voltage cables can be erected using this type of bridge.

In addition, the tray-type cable tray is another cable tray with a wide range of uses. Its structure is very simple, and its weight is much lighter than other types of cable trays. If a large span is required, a large-span cable tray made of fiberglass materials is generally used. This kind of cable tray has a very long service life, is light in weight, and is easy to cut.
