The galvanized coating is created by dipping the steel into molten zinc, which forms a protective layer on the steel surface. Zinc is an extremely sacrificial material, meaning it will corrode before the steel does. This means that even if the zinc layer is damaged, the steel underneath will still be protected. Galvanized coatings are affordable and easy to apply, making them a popular choice for a variety of applications.
Advantages of galvanized steel
The zinc layer acts as a sacrificial layer, protecting the steel underneath from corrosion.
It can be cut, bent, and formed into a variety of shapes without affecting its strength.
No painting or coating is required, which reduces overall maintenance costs.
Disadvantages of galvanized steel
The zinc layer will wear out over time, especially in harsh environments.
Galvanized coatings do not offer the same degree of corrosion resistance as galvanized coatings.
