Cable tray dip coating process
Steel trays get dipped in very hot molten zinc (around 450°C). The zinc bonds tightly to the steel, creating a thick, tough layer. Process: Degreasing → Pickling → Rinsing → Fluxing → Drying → Hot-dip galvanizing → Cooling → Passivation (optional) → Inspection. Hot-dip galvanizing is a process that enhances the durability of cable trays by creating a protective zinc coating, safeguarding them from corrosion. It is cost-effective, protects against a wide variety of environmental chemicals, and is self-healing if an area becomes unprotected through cuts or scratches. Steel is coated with zinc through electrolysis by dipping steel into a bath of. Legrand's offer of global solutions for wiremesh cable trays (and accessories) is one of the most complete on the market. It offers true freedom by allowing multiple configurations in a wide choice of finishes for optimal integration into any environment.
