Large-scale / Tubes-line Galvanising

Large-scale galvanising is performed manually at the tubes line with a maximum daily capacity of 1,500 kg of electroplated components.

  • mildly acid galvanising bath
  • standard thickness of zinc coating 5-8 microns (or as requested by customer)
  • maximum weight of galvanised component: 200 kg
  • blue, hexavalent-chromium-free passivation – ‘blue zinc’
  • yellow chromate containing hexavalent chromium – ‘yellow zinc’
  • thick-film hexavalent-chromium-free passivation (used as a substitute for yellow chromate)
  • anticorrosion resistance of all of the above surface finishing methods may be increased by combining them with a final application of transparent sealing coating
  • prices for large-scale galvanising quoted in CZK per kg
