  • Most galvanizing operations are privately held
  • Sales range from $10 million to $50 million
  • Most galvanizing operations do not take title to the steel they galvanize.
  • These operations are called "job" or "custom" galvanizers and they provide a service.


Other coatings (paint, powder coating), weathering steel, stainless steel, wood, aluminum, concrete and composites

Galvanizing Process

  • Cleaning the steel in a degreasing solution.
  • Pickling in dilute hot sulfuric acid or ambient temperature hydrochloric solution.
  • Fluxing in an aqueous solution of zinc-ammonium chloride.
  • Immersing in a bath (kettle) of molten zinc.
  • Inspection of material for consistent and thorough coating.

AGA members represent approximately 95% of the industry capacity. Non-members are primarily smaller galvanizers, pipe, wire and fence companies, but consolidation has changed the face of the industry in the last 10 years. There are now several multi-plant public and private operators.
