The galvanising pot is the core equipment in the hot-dip galvanising process, serving as the vessel for holding molten zinc. It enables metal workpieces to acquire a zinc coating by immersion in the molten zinc bath.

Zinc pot dimensions must be determined based on workpiece size and production process. The effective length requires a safety margin of 0.5 to 1.5 metres beyond the maximum workpiece length; The effective width must incorporate a safety margin of 0.3 to 0.8 metres beyond the maximum workpiece width or lifting equipment width. Effective depth must account for the maximum workpiece height, zinc immersion depth, dross zone height, and safety margin for liquid level fluctuations.

The pot body of internally heated ceramic zinc pots comprises three layers of insulation material—a casting layer, thermal insulation layer, and heat retention layer—supported by a steel structural frame. This design ensures high thermal stability and a long service life exceeding 10 years.
