Zinc plating

 

As an additional option for all sheet metal, tube or profile parts on offer, they can be protected against corrosion through hot-dip galvanisation. In order to meet the expectations of our customers, we have established cooperation with a galvanising plant where, at the customer's request, we order galvanising of the semi-finished products sold by us. The proposed hot dip galvanising effectively protects steel components against corrosion. The first stage is degreasing, the purpose of which is to remove any greasy impurities, followed by etching, i.e. the removal of rust and scale. The next stage is the so-called fluxing, i.e. immersion in flux, which ensures the proper course of the reaction during subsequent immersion of the component in molten zinc. Before the workpiece is dipped into the zinc bath, it must undergo a drying process to allow the liquids from the previous stages to evaporate. The final stage is the immersion of the steel component in the bath (bath dimensions 7000x1400x3000 mm) filled with liquid zinc, which has a temperature of 445-455 ºC, and as a result of the reaction of the iron in the steel with the zinc, an iron-zinc alloy is formed, which produces a protective coating on the component both on the outside and the inside of the immersed workpiece.
