Zincatura Botter offers electrogalvanisation of metals, a surface treatment consisting of the application of a zinc coating on a steel product in order to protect it from galvanic corrosion.
Cold electrogalvanisation is used to treat metal pieces of different sizes intended for application in a wide range of different fields, from the automotive sector to the mechanical industry and lead steel fittings. The pieces are immersed in a chemical solution which favours respect of the product’s project dimensions, including all types of threading. On the metal surface zinc ions are deposited in a very homogenous layer due to direct current (DC) passing from the positive to the negative pole. Differing from hot galvanisation, electrogalvanisation allows 8, 10 and 12 micron tolerance of threads.
