Specifying Hot Dip Galvanizing

Designers wishing to specify hot dip galvanizing (HDG) need only use two Standards:

  • Design and durability of HDG steel AS/NZS 2312.2:2014
  • Manufacturing process and tolerances AS/NZS 4680:2006.

Hot dip galvanizing has proven to be more serviceable and predictable than all other steel protective coatings in the New Zealand atmosphere. Its excellent performance is due to its inherent corrosion resistance, high tolerance to mechanical damage and inertness to the high UV levels prevailing over all of New Zealand.
