The Hot Dip Galvanizing Process



The Hot Dip Galvanizing Process
Fabricated steel products are carefully attached to a overhead lifting device in the hot dip galvanizing plant then dipped in a series of tanks filled with chemicals to remove surface contaminants such as dirt, paint, oil, grease and rust. The first chemical tank is a heated caustic solution followed by the hydrochloric acid pickling solution to remove mill scales and rust. The cleaned steel is then dipped into a heated Flux solution. Upon drying the article is then dipped into a pot of hot molten zinc. The final stage is to quench the hot dipped galvanized steel by dipping it into a final passivation solution.

  1. Individual metal articles, such as steel girders or wrought iron gates, can be hot-dip galvanized by a process called batch galvanizing. Other modern techniques have largely replaced hot-dip for these sorts of roles. This includes electrogalvanizing, which deposits the layer of zinc from an aqueous electrolyte by electroplating, forming a thinner and much stronger bond. Hot Dip Galvanizing Plant
