More accurately termed a refractory zinc pot, its core consists of a pot body constructed from special refractory materials such as silicon carbide. They boast exceptionally long lifespans exceeding 10 years, minimal zinc consumption and slag production, and high safety reliability. However, they entail high initial investment, slow heating rates, and challenging maintenance.

The structural design of galvanising pots is rational. For instance, the heaters in internally heated ceramic zinc pots are vertically and uniformly installed on the pot's inner wall, facilitating operation and maintenance. The pot body's steel plate frame is welded from high-quality steel, ensuring overall strength and operational safety and reliability.
