What is Hot Dip Galvanizing


Hot dip galvanizing, according to the American Galvanizers Association, is defined as the process of dipping fabricated steel into a kettle or vat containing molten zinc.

This process helps protect metal from corrosion. This is one of the most effective ways to protect steel and metal from rust. The molten zinc provides a barrier that doesn’t allow any moisture to touch the metal, thus ensuring no rust can form.

Hot Dip Galvanizing Process

The first step in the steel protection process is to completely clean the surface of any item to be hot dipped galvanized. This is important as the molten zinc coating will not form a complete metallurgical bond with the item if it is dirty. The steel will move through a series of cleaning steps including degreasing, pickling, and fluxing. The degreasing step helps remove dirt, oil, and other residues while the pickling step helps remove mill scale and iron oxide. Fluxing helps remove any remaining oxides left on the surface after the first two steps are completed. The steel is coated with a protective layer to prevent further oxide formation before it is galvanized.

Once the steel is prepped, it is dipped into a molten bath of at least 98% zinc at an angle to prevent air pockets. The iron in the steel metallurgically reacts with the zinc to create a zinc coating. After, the piece is inspected to ensure it was properly coated.

Hot Dip Galvanizing Benefits

Hot dip galvanizing provides a variety of benefits including:

  • Creates a barrier between the steel and the environment
  • Makes the surface abrasion-resistant
  • Provides complete coverage of the steel
  • Offers a long, maintenance-free life span
