Competitively priced
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 Maintenance |
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 |
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.
