The hot dip galvanization is the process of coating iron or steel with a thin zinc layer, by passing the steel through a molten bath of zinc at a temperature of around 460 °C.
When exposed to the atmosphere, pure zinc reacts with oxygen to form zinc oxide, which further reacts with carbon dioxide to form zinc carbonate, a dull grey, fairly strong material that stops further corrosion in many circumstances.

The stove are covered by steel completely. The inner parts are installed with most advanced fire resistant materials. It is very safe. There is no chance for any lead leakage. There are one layer heat insulation material in the outside. It reduces heat loss.
It equipped with U type tower. Press roller adopts pure iron roller with auto left device.
The wire will be scrapped by medium when it leaves the galvanizing tank. It pass through wind blow and cooling by cold water
