The trough type cold galvanized cable tray is a fully enclosed cable tray that has undergone cold galvanizing processing. Trough type cable tray is one of the best cable trays for cable protection, as it is fully enclosed and can effectively reduce cable shielding interference and corrosion. However, this also requires the cable tray to have good corrosion resistance. Cold galvanizing treatment for the tray is to improve its corrosion resistance.

Place the cable tray in a solution containing zinc salts, and use electrolysis equipment to allow zinc to precipitate on the tray, forming a layer of zinc to protect the metal inside.

The cold galvanizing process is more environmentally friendly than traditional galvanizing because it does not contain heavy metals such as * * * and toxic organic solvents such as toluene. In addition, the zinc film thickness of cold galvanizing is much thicker than traditional galvanizing, which also saves costs. Therefore, cold galvanizing is an energy-saving and environmentally friendly galvanizing process.
