1. Longest life durability
In dry area and rural environments, for example, products with the 610g/m2 average adhesion coating can be stored for more than 60 years without repair. Whereas in poorer conditions, such as urban or coastal areas, products can be maintained for 20 to 25 years and do not need any repair.
2. Lowest maintenance costs
Owing to the excellent weather-resistance hot-dip galvanized products can be utilized for very long period and do not have to spend any repair costs. Compared to the regular maintenance of paint coating, it saves a lot of money and social costs.
3. Excellent solid effect
Galvanized coating with alloy structure has excellent hardness and mechanical properties.
4. Superior protective effect
Due to zinc has higher chemical activity than iron, the exposed steel surface even with minute defects can be protected which is the protection features of sacrificial anode.
5. Protection of no dead space
According to the operating characteristics, the hot-dip galvanized workpiece must be immersed in the zinc bath completely. So each corner of the workpiece can be contacted absolutely, especially the sharp tips and concave areas can get thicker coating layer of zinc. This is also the superiority over the spray coating.
6. Without impacts on the original design
Hot-dip galvanizing maintains the mechanical properties of the general structures without any impacts.
7. With rapid and time-saving operations
Hot-dip galvanizing operations can be accomplished in the factory despite the weather and the manufacture duration can be controlled assuredly.
8. Reliable and trustworthy properties
Superior physical and chemical stabilities of the galvanized coating are definitely worth of your trust, unless the surrounding environments are deliberately changed.
9. Fit for long-term utilization
Galvanizing costs more at present, but it lasts long. Although spray coating is cheaper, it needs regular maintenance. As long as the spray coating is repaired the first time, the overall cost would be more than the cost of hot-dip galvanizing.
10. Lowest cost
Because of the extreme long durability, the apportioned cost of galvanizing assessed by initial investment becomes negligible.
11. Minimal changes of costs
The changes in labor costs of hot-dip galvanizing arise stably, whereas those of spray costing are hardly predicted.
12. Easy inspection of the appearance
Any defects in galvanizing quality will be identified easily with naked eyes without sophisticated instruments.
13. High renewability
As long as he workpiece is not damaged though galvanized coating expired, it can be dismantled and re-galvanized and then return to brand-new conditions again.
