Galvanizing is a Metallurgical Bond

Unlike paint coatings Hot Dip Galvanizing fuses zinc with the iron in the steel to form permanent layers. This microscopic view displays the typical transition layers.

One Advantage of Galvanizing is Sacrificial Corrosion Protection or Self Healing Small area end cutting or local damage to a hot dip galvanized item is usually protected due to the surrounding zinc becoming an anode for the exposed steel.

Top Tips prior to Galvanizing

8 Tips for Architects

  1. Understand the corrosivity of the region AND the local area
  2. Hot dip galvanizing (HDG) slows steel corrosion rate by 10 – 40 times
  3. HDG steel needs far less maintenance than other coatings
  4. Steel thickness and chemistry can further increase durability of HDG
  5. The appearance of HDG steel will change over time from silver to a uniform matte grey
  6. Communicate! Talk to the fabricator and galvanizer in the design phase for complex designs
  7. Seek assistance if the need to specify ('hot dip galvanized to AS/NZS 4680')
  8. Hot dip galvanizing costs less, lasts longer and is faster to erect in most situations

8 Tips for Engineers & Designers

  1. Understand the corrosivity of the region AND the local area
  2. Hot dip galvanizing (HDG) slows steel corrosion rate by 10 – 40 times
  3. Communicate! Talk to the fabricator and galvanizer at the design phase for complex designs and appropriate steel selection
  4. Steel thickness and chemistry can further increase durability of HDG
    • Good quality welded or bolted connection prior to galvanizing
    • Avoid air and moisture traps
    • Include large drainage holes and gussets are cropped
  5. HDG is the most cost effective protection for modular designs
  6. HDG steel needs less maintenance than other coatings
  7. Seek assistance if the need to specify ('hot dip galvanized to AS/NZS 4680')
  8. Hot dip galvanizing costs less, lasts longer and is faster to erect in most situations

10 Tips for Fabricators

  1. Consult with your galvanizer on transport, product dimensions prior to fabrication to ensure your article fits
  2. Select the steel composition required up front for consistent galvanizing appearance (call for assistance)
  3. Weld prior to galvanizing to eliminate repairs afterwards
  4. If possible, use bolted connections for ease of assembly
  5. Grind back thermally cut sharp edges after processing
  6. Avoid air and moisture traps to improve quality
  7. Good welding will eliminate pinholes & galvanizing misses
  8. Large drainage holes & crops improve the finished quality
  9. Suitable hanging holes & points help with quality
  10. Use water-based markers
