Mechanical Galvanizing vs. Hot Dip Galvanizing Process

Hot dip galvanizing is the process of coating parts with molten zinc by immersing them in a bath of molten zinc at a temperature around 840°F (449°C). This results in a zinc coating of 0.002” or greater which prevents corrosion.

Advantages of Mechanical Plating over Hot-Dip 

  • Better sacrificial protection, no hydrogen embrittlement
  • ASTM B695 has salt spray requirement, hot dip galvanizing does not
  • Room temperature process, no detempering
  • Parts will not get stuck together, no reworking of threads
  • Lead-free, Prime Western Zinc used in hot dip contains lead and is not RoHS compliant.
