When compared to alternative coatings, hot dip galvanizing is extremely cost competitive. It’s particularly cost-effective for jobs with medium to high corrosion protection needs.
|Coating System||Initial Cost of Application of
Hot Dip Galvanizing Other
Coating vs Hot Dip Galvanizing
|HERA rating||Time to First
|Total DFT μm|
|Hot Dip Galvanized||0.98 to 1.31||25||85|
|Inorganic Zinc Silicate||Comparative Initial Cost||1.00||25+||125|
|Acrylic Two Coat||Similar Initial Cost||1.10||10||125|
|Epoxy High Build One Coat||1.23||15||275|
|Acrylic Three Coat||Higher Initial Cost||1.30||15||250|
|Polyurethane Three Coat||1.40||15||250|
|Thermal Zinc Spray Sealed||1.47||25+||100|
|Epoxy High Build One Coat||1.77||15||400|
|Epoxy Mastic Two Coat||1.93||10||400|
The cost of hot dip galvanizing is extremely competitive particularly for small to medium sized structural members.
When you consider life of asset value, hot dip galvanizing is in a class of its own, delivering accumulated maintenance cost savings that is unmatched.
|Coating System||Life Cycle Cost Application of Hot Dip Galvanizing vs Other Coating|
|Over 25 years||Over 50 years|
|Inorganic Zinc Silicate||Similar Cost||Lower Cost|
|Acrylic Two Coat||Lower Cost||Significantly Lower Cost|
|Epoxy High Build One Coat|
|Acrylic Three Coat|
|Polyurethane Three Coat|
|Thermal Zinc Spray Sealed|
|Epoxy High Build One Coat||Significantly Lower Cost|
|Epoxy Mastic Two Coat|
Hot dip galvanizing significantly reduces the cost of maintenance over the life of the asset, when compared to other coating systems.
