What type of aluminum is used for cable trays

A cable tray is made of the best material, the 6063-T6 aluminum. This particular form of metal is the most preferred metal in the industry since it is powerful, light, and not easy to rust. Imagine a robust bridge or a shelf that has been constructed in order to hold power cables. 1 Is aluminum. Aluminium Cable Trays: While durable, aluminium lacks the same strength as steel and is prone to deformation under heavy loads. This makes it easier to handle and install compared to steel cable trays, especially in large - scale projects. It also reduces the load on the supporting structures. due to a thin, continuous natural oxide film (alumina) that protects ies aluminum alloys (Aluminum Association designation) to manufacture cable tray.
