Developed with and administered by the Australasian Corrosion Association, the objective of this two-day course is to train individuals to correctly assess the suitability of fabricated steel articles for the hot dip galvanizing process and to correctly inspect hot dip galvanized steel articles to ensure compliance to Australian, New Zealand and international Standards. After successful completion of the course the participants become a Certified ACA Hot Dip Galvanizing Inspector.

The course content includes:

  • An introduction to corrosion and its prevention
  • Local & international hot dip galvanizing Standards
  • Design considerations for inspection before galvanizing
  • The hot dip galvanizing process
  • Metallurgy of the hot dip galvanized coating including the effect of steel chemistry and surface conditions
  • Typical surface conditions – description and extensive visual examples
  • Repair of damaged and uncoated areas of galvanized steel
  • Inspection of jobs before, during and after galvanizing
  • Development of inspection and test plans, including simulated project inspection and test plans
  • Statistical sampling for Test Reports
  • Practical testing of real project items


The course is open to people with either an ACA, NACE or equivalent current coating inspection certificate or those with at least 12 months experience in a galvanizing plant. Courses are held 2-3 times per year in a galvanizing plant to provide real-world experience with inspection.

A list of current accredited inspectors is available here. Please contact the GAA or the ACA if you wish to enroll in a course and contact the GAA to obtain further details of independent inspectors.
