|Epoxy High Build One Coat||1.77||15||400|
|Epoxy Mastic Two Coat||1.93||10||400|
Based on HERA Report R4-133:2011
The cost of hot dip galvanizing is extremely competitive particularly for small to medium sized structural members.
Unbeatable value over life-of-asset
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|
Based on GAA Life Cycle Cost Calculator
Hot dip galvanizing significantly reduces the cost of maintenance over the life of the asset, when compared to other coating systems.
