Steel is often considered to be one of the best materials, but is there a way that something can be better than it? Well, the answer is “yes”. There is a superior form of steel, which is galvanized steel. What makes galvanized steel superior? The coating. This type of steel is coated with zinc oxide, which prevents the material from rusting. Thanks to zinc oxide, it takes galvanized steel longer to start corroding than steel. But that’s only the peak of the iceberg of the benefits of galvanized steel.
The Benefits of Galvanized Steel
Well, one can say that zinc oxide changes the way the steel looks. It provides it with a rugged appearance that some people prefer. Also, the risk of corrosion is less, so that’s the end of the story. But it’s clearly not. Galvanized steel wouldn’t have become such a popular material just for its looks. Being more resistant to the corrosion also doesn’t sound like the ultimate way for the popularity of the material. So, what are the main benefits of galvanized steel?
Steel is mainly the alloy of iron and carbon. Unfortunately, iron is extremely inclined to rust. Especially when exposed to moisture or oxygen. Galvanized steel is incredibly resistant to rusting thank to zinc oxide. Turns out this inorganic compound works as a perfect buffer between steel and its rusting triggers.
Zinc oxide is the coating of the still, it never lets the steel to corrode. When the galvanized steel gets damaged, it gives you enough time to figure out what to do delaying the effect. As it is always zinc oxide that gets damaged first. While the coating may start experiencing corrosion, the steel remains safe.
While you need to make a few tests to realize that the steel is damaged, as you may notice the damage only when it is too late, things are absolutely different from its galvanized counterpart. As it was mentioned above, the zinc oxide coating is the first thing to get damaged. Thus, while there is a simple test to check how thick zinc is, you can tell whether the galvanized steel is okay or not by simply looking at the coating.
One of the main advantages of galvanized steel is its longevity. The galvanized steel is generally expected to last over fifty years. Moreover, it can last up to thirty years after severe water exposure without requiring any sufficient maintenance.
The Process of Galvanization
So, how does galvanized steel work? The process of galvanization is fairly simple. The vast majority of manufacturers simply dip the steel into molten zinc. Zinc oxide simply bonds to the steel, which makes it more than just coating, as it becomes a part of chemical composition of the steel. Thus, galvanized steel is not simply a steel interior with a protective coating made of zinc, but a combination of both metals. But you can achieve that only by dipping the steel into the zinc. If you want to apply zinc oxide simply as the coating, you can simply spray it on the steel, but it won’t have the same lasting effect as dipping.
