A one-time process, hot dip galvanizing ensures maintenance-free use of steel. The use of hot dip galvanizing for structural steel protection gives 10 important, measurable benefits:
1. Lowest first cost.
Compared to many other protective coatings for steel, hot dip galvanizing has the lowest first cost of protection.
2. Lowest long-term cost.
As hot dip galvanizing provides longer life protection and requires little maintenance for steel, it achieves the lowest long-term cost by eliminating the need for periodic plant shutdown and production disruption.
3. Super long life.
The life expectancy of hot dip galvanized coatings on typical structural members averages far in excess of 50 years in most rural environments and even in severe urban and coastal exposure.
4. Guaranteed reliability.
Hot dip galvanizing is carried out to strict international standards, where specific coating thickness is applied to achieve reliable coating life and performance.
5. Strongest coating.
The unique metallurgical structure of hot dip galvanized coating gives outstanding resistance to mechanical damage in transport, erection and service.
6. Automatic protection.
Hot dip galvanized coatings corrode preferentially to steel via its sacrificial protection to small areas of exposed steel.
7. Comprehensive protection.
Every part of a hot dip galvanized structure is protected, including recesses, sharp corners and inaccessible areas. No other coating can provide such comprehensive protection.
8. Ease of inspection.
It is very easy to inspect the state of hot dip galvanized coatings - simply via visual observation or non-destructive thickness testing methods.
9. Speedy construction.
Hot dip galvanized steel is ready for final installation upon delivery. There is no need for on-site surface preparation, painting and inspection. This saves substantial construction time and money.
10. Independent of weather.
A four-coat paint system requires a week to complete. The hot dip galvanizing process is not dependent on weather conditions and every hot dip galvanized structure is ready-for-use.
