What is the Difference Between Galvanization and Zinc Plating?

Both galvanization and zinc plating are popular in the metal finishing industry. Although galvanization is an application of zinc plating, it has a much more different finishing process with different thicknesses compared to zinc plating. Knowing which type of plating to choose can significantly benefit your business and make your parts last longer. This will also guarantee that your customers will keep coming back to you. In this article, we will specify the differences between galvanization and zinc plating.


  • Needs to be submerged in molten liquid zinc 

  • Produces a dull finish and is 50 microns thick

  • Temperature tolerance of 392 ℉

  • Prevents corrosion and rusting

  • Long life expectancy

  • Superior resistance to mechanical damage

  • Less maintenance

  • Used for large structural shapes, especially in the construction industry

Zinc Plating 

  • Involves electroplating: needs to be immersed in a zinc salt solution before an electric current is applied to it

  • Produces a shiny finish and is 3 microns thick

  • Temperature tolerance of 120 ℉

  • Corrosion-resistant

  • Low cost

  • Indoor usage preferences

  • Used for small parts, such as nuts, bolts, automotive and fabricated parts to use in industrial applications
