Galvanized cable tray is a bracket that supports and holds cables. It is very common in engineering projects; wherever cables are laid, cable trays are used. As a supporting component in wiring projects, cable trays are divided into trough-type, tray-type, and ladder-type structures, consisting of supports, brackets, and installation accessories.

Galvanized cable trays are divided into trough-type, tray-type, and ladder-type structures, composed of supports, brackets, and installation accessories. When selecting a type, it is important to ensure that all components of the cable tray meet the requirements of serialization, generalization, and standardization. Inside buildings, cable trays can be installed independently or attached to various structures and pipe gallery supports. They should feature a simple structure, aesthetic appearance, flexible configuration, and easy maintenance. All parts must be galvanized. For cable trays installed outdoors on buildings, especially in coastal areas or corrosive environments, the material must possess anti-corrosion properties, resistance to moisture, good adhesion, and high impact strength.

To reduce weight, aluminum alloy cables and fiberglass cable trays can be used. Their dimensions and load-bearing characteristics are largely similar to those of steel cable trays. Due to the difference in density between aluminum and steel (Al=2.7, Fe=7.86), the weight ratio of aluminum to steel is approximately 1:3. Based on the market prices of the two materials, the cost of aluminum alloy cable trays is about 2.0 times higher than that of galvanized steel cable trays. Aluminum alloy cable trays offer advantages such as an attractive appearance, light weight, and ease of installation. In recent years, aluminum alloy cable trays have been applied in some engineering projects.
