Bot: Steel is a materials widely used in a wide range of industries and is very durable. Its toughness and durability mean it will last. The issue with steel though, according to some manufacturers, is that steel has a tendency to get rusty after being subject to moisture or water for a prolonged period of time. There are two common ways to prevent rust from forming on steel, galvanization and coatings. These you methods put a protective coating over the steel to help keep it tough for longer. So what is the difference between both in terms of galvanized steel and coated steel and which is the better choice for different applications? Let's learn more about this topic.
The Advantages and Disadvantages of Galvanized and Coated Steel
First, let’s address galvanized steel. This kind of steel has a coating of zinc. Modern zinc is a metal that inhibits the formation of rust. Galvanization is done by dipping the steel into a molten bath of zinc, and it causes the steel to get completely covered in zinc. When the hot-dipped galvanizing process is completed, the resulting galvanized steel is extremely robust and ideal for outdoor applications that are exposed to rain, snow and the elements.
Now, let us turn to coated steel. There is a layer of paint or plastic that protects this kind of steel. This layer serves as a shield, blocking moisture and other damaging agents from penetrating the steel below. Coating is done in several forms which includes powder coating, liquid coating, and electroplating. Coated steel, just like Galvanized Steel Pipe, is strong and durable, but it has a different type of protection.
So conditioned steel is actually more prone to damage than galvanized steel, which is the one advantage of galvanized steel. This makes galvanized steel pipe much more resistant to scratches and bumps than coated steel. But there is a downside trade-off. Galvanized steel does not look as good as coated steel. Steel typically has a dull gray appearance, whereas coated steel could be several colors and finishes more visually appealing.
304 vs 316 Stainless Steel – Which is Better for Use?
Galvanized steel vs Coated steel: When comparing them there are many pros and cons associated with respective types. Galvanized steel wins when it comes to overall durability and longevity. Due to this fact, it is better against rust and corrosion than coated steel, therefore incredibly effective in difficult outdoor conditions. With its durability, 3 inch galvanized steel pipe is able to withstand exposure to moisture, salt water, and other corrosive materials without any large amounts of damage.
Coated steel, on the other hand, can offer some level of rust and corrosion resistance as well, but not quite as durable as galvanized steel. That layer of paint or plastic can chip, crack, or peel, especially if scratched, over time. If this occurs, water can penetrate to the steel beneath, which can cause rusting and other damage.
Differences Between Galvanized and Coated Steel
So now we explore how galvanized and coated steel stand up against each other point for point. That said, there are a few key things to know:
Galvanized Steel:
Generally, it has a greater stability and a greater lifespan than steel with a coating.
For outdoor use, it has a better resistance against rust and corrosion.
It is more resistant to scratching and stands up better to abrasions.
But it also looks less attractive with its dull gray color.
With prolonged exposure to moisture, galvanized steel can develop a condition called "white rust."
Coated Steel:
Coated steel typically looks better and is available in a wide range of colors and styles.
It offers some rust and corrosion protection, but it isn't nearly as strong as galvanized steel.
It is less resilient than galvanized steel, and can also chip, crack, or peel more easily.
It might need to be maintained more to keep it looking nice and to avoid damage.
Galvanized Steel Most common type Galvanized / Coated Steel
When talking about durability and how long the steel will last, galvanized steel is mostly the better solution. It provides enhanced protection from rust and other forms of corrosion, so is a good choice in exterior environments where it would be exposed to harsh weather conditions. But coated steel also has its unique advantages, particularly around aesthetics. Coated Steel: a great option if you want something that looks good and has some protection with it.
