Galvanized vs. Galvannealed Steel: How Do They Stack Up?


If you’re familiar with steel or have worked with sheet metal in any capacity, you’ve probably heard the terms “galvanized” and “galvannealed” in reference to steel.

They might sound like different places in the Star Wars universe but galvanized steel, and galvannealed steel are just two classes of a greater group of metals. The difference between them lies in their manufacturing process.

We’re going to take a look at the differences and how you could benefit from each, so keep reading!

What Is Galvanized Steel?

The galvanization process involves plating a steel product with a fine layer of zinc. This protects the base material from corrosion and also gives it a more attractive finish.

Zinc is a non-corrosive metal, so it can protect the steel from rusting. It can be applied to steel by dipping it in molten zinc, or by electroplating it.

What Is Galvannealed Steel?

Galvannealed steel is a type of galvanized steel that has been further coated with a layer of zinc-iron alloy.

The process of galvanizing steel involves passing it through a molten bath of zinc; this causes an electrochemical reaction and bonds the metal to the surface of the material.

Galvanneal steel differs from traditional galvanized steel in that instead of just having its surface covered with zinc, it is given an additional layer that contains iron as well. This can protect against rusting better than traditional galvanized steels because this extra layer helps prevent water from reaching deep into the material and causing corrosion underneath.

Is Galvannealed Better Than Galvanized Metal?

It’s interesting to note that galvannealed has a lower melting point than galvanized steel, so it can be heated and shaped easily.

It also has a harder surface than galvanized, which means that it will retain its appearance for longer. In addition to its superior durability and appearance, the increased strength of galvannealed also makes it more expensive than galvanized steel.

So should you use galvenealed over galvanized?

That depends on your needs. If you need something strong yet inexpensive for outdoor projects like fencing or decks, then the extra cost of using galvenealed is probably not worth it in terms of value.

However, if you want something more aesthetically pleasing indoors—like kitchenware or furniture—then I would recommend using galvenealed over galvanealed every time!

What Are the Drawbacks?

Galvannealed steel is more expensive than galvanized steel. However, its cost can be justified by its superior performance in terms of durability, strength, and appearance.

Galvannealed steel is not as strong or as durable as stainless steel, especially when used in large or heavy products.

For the coating to maintain its color over time, it must be painted soon after it is produced. Otherwise, the coating will develop a white discoloration that will not protect the underlying metal from rusting.

Use Galvannealed Steel For Extra Protection

If you’re looking for the most durable steel available, galvannealed steel is the solution you need. It’s a great option for outdoor applications like storage sheds and patios because it can withstand moisture better than other types of metal.
