HDG Datasheet 3: Hot Dip Galvanizing of Small Components

Small articles may be galvanized by a variation on the standard hot dip galvanizing process and is known as ‘Spin Galvanizing’ or Centrifuge Galvanizing.

In centrifuge galvanizing (or spin galvanizing) the work follows the same process route as for larger articles except the items are loaded into a basket which is spun at high speed immediately after removal from the molten zinc.

This removes surplus zinc and improves the uniform distribution of the zinc coating, while preventing pieces from sticking together. Work is normally quenched immediately after centrifuging.
