Aluminum alloy cable trays have many excellent characteristics: they have a beautiful appearance, simple structure, unique style, as well as strong load capacity and light weight. Not only that, when the surface of the aluminum alloy cable tray is anodized, it also has anti-corrosion performance and can effectively resist electromagnetic interference, especially in terms of shielding interference, which is more outstanding. This advantage cannot be replaced by steel cable trays. Therefore, the application range of aluminum alloy cable trays is very wide, not only meeting the needs of inland and pollution-free areas, but also fully demonstrating its unique anti-corrosion superiority in coastal salt spray areas, high humidity environments, and areas with corrosive pollution. Therefore, it is widely used in power plants, chemical, petrochemical and other fields.
