Hot dip galvanizing

In order to ensure a comprehensive, efficient, durable and economical corrosion protection for your steel components, we approach the hot-dip galvanizing systematically - from bath to bath and always with the utmost precision. First, the metal parts are wet-chemically pretreated in different baths. They pass through a degreasing bath that removes the grease residues from the surface. In the following water-rinse the residues of the degreasing agent are rinsed. Next, the parts are treated in the pickling bath. Inherent residues like rust and scale are removed with diluted hydrochloric acid. In the flux bath – in a similar way as when soldering - substances are added. These perform a final "fine cleaning" of the steel surface when dipped into the molten zinc. This process ensures additionally that the entire surface is uniformly wetted while galvanizing. Prior to that, the aqueous flux film on the steel part is dried in a drying oven. Now the actual galvanizing of the steel part in the zinc pot follows. The melting point of zinc is 419 °C, whereas the liquid zinc is run up to an average of 450 °C in the boiler. Hot-dip galvanizing in one of the most modern plants in Europe!
