Hot Dip Galvanizing

Hot Dip Galvanizing is one of the oldest methods of zinc coating which involves immersion of a fastener in molten zinc to provide a corrosion protecting finish. This zinc coating provides sacrificial or cathodic protection to the steel. Because zinc is more reactive than iron, the zinc galvanized coating corrodes first, protecting the steel substrate. The appearance of the galvanized surface can vary from shiny silver to a dull matte gray finish depending upon variables such as the steel composition, rate of withdrawal from the molten zinc bath and cooling method. The dark gray matte finish will provide just as much corrosion protection as the shiny appearance. Our domestic sources are qualified and utilize in-process quality systems enabling us to maintain full traceability from raw material to each container of product we ship. Chemical and physical certifications are provided with every shipment.

Hot Dip Galvanizing Benefits.

  • Lower first cost. Hot dip galvanizing generally has the lowest first cost when compared to other commonly specified comparable protective coatings for steel. The application cost of labour intensive coatings such as painting has risen far more than the cost of factory applied hot dip galvanizing.
  • Lower maintenance / lower long term cost. Even in cases where the initial cost of hot dip galvanizing is higher than alternative coatings, galvanizing is invariably more cost effective, due to lower maintenance costs during a longer service life. Maintenance is even more costly when structures are located in remote areas. Maintenance programmes also invariably have a negative impact on productivity.
  • Long life. The life expectancy of hot dip galvanized coatings on structural members is in excess of 50 years in most rural environments, and between 10 to 30 years in most corrosive urban and coastal environments.
  • Surface preparation. Immersion in acid ensures uniform cleaning of the steel surfaces, in contrast organic coatings must be applied on abrasive blast cleaned surfaces (generally to ISO 8501 – 1 to SA 2) and verified by third party inspection. Additionally, the application of organic coatings is limited in terms of prevailing ambient temperature and relative humidity. This adds to the cost of applying a heavy duty paint system.
  • In hot dip galvanizing, all surfaces receive equally goad coatings.
  • Speed of coating application. A full protective coating can be applied in minutes, a comparable multicoat paint system, may require up to a week. The effective application of a hot dip galvanized coating is not influenced by weather conditions.
  • Reliability. Hot dip galvanizing is required to conform to the ISO 1461 specification. The coating thicknesses specified are related to steel thickness. Coating life is reliable and predictable.
  • Ease of Inspection. Hot dip galvanized coatings are readily assessed visually. Simple non-destructive testing methods are used to determine coating thickness. Inspection of organic coatings is necessary after surface preparation and each stage of coating application thereafter. The hot dip galvanizing process is such that if coatings appear sound and continuous, they are sound and continuous.


  • Hot dip galvanizing can only be done in a galvanizing plant. Site application is not possible.
  • The dimensions of the component or structure are limited by the size of the zinc bath. Refer to the current copy of Hot Dip Galvanizing Today (Association journal) for available bath sizes or contact the Association.
