As an effective method of metal corrosion prevention, hot-dip galvanized cable trays and hot-dip zinc coated cable trays have been widely used on metal structural facilities across various industries, offering corrosion resistance for over 10 years.

The hot-dip galvanized cable tray employs a chemical process, which is an electrochemical reaction. This reaction fuses the molten metal with the iron substrate to form an alloy layer, thereby combining both the substrate and the coating. The hot-dip galvanizing process begins with cold-rolled steel sheets being shaped into trays and then pickled to remove the surface ferric oxide. After pickling, the trays are cleaned in a bath of ammonium chloride or zinc chloride aqueous solution, or a mixture of both. The treated trays are then immersed in the hot-dip galvanizing tank.

Hot-dip galvanized cable trays offer advantages such as even coating, strong adhesion, large-span cable trays, reliable coating that's not prone to peeling, thick zinc coating for excellent corrosion resistance, and a long service life. Of course, for high corrosion resistance, there are also stainless steel cable trays and aluminum alloy cable trays, among others, which can be selected based on engineering requirements.
