Steel Pipe vs Galvanized Pipe – What’s the Difference

Steel Pipe vs Galvanized Pipe

If you’re looking for a reliable pipe for your next project, chances are you’ll come across two popular options—steel pipe or galvanized pipe. While both can be effective for specific uses, it’s important to understand their differences before making a final decision. Let’s look at steel pipe vs galvanized so that you can make an informed choice.

Steel Pipe

Steel piping is made from raw steel formed into a circular shape and then welded together to create a seamless pipe. It is incredibly strong and durable, but it also has the potential to rust when exposed to moisture over time. For this reason, steel piping should only be used outdoors where its exposure to the elements is limited. In addition, steel pipes must be treated with a protective coating to prevent corrosion and rusting.

Galvanized Pipe

Galvanized pipes are made from steel that has been coated with zinc. This coating helps protect the steel from corrosion and rusting—even if it’s exposed to moisture over time—which makes it ideal for outdoor projects such as plumbing systems or irrigation systems. The zinc coating also provides additional strength and durability compared to standard steel pipes, which means they can withstand higher pressure levels and more extreme temperatures.

Difference Between Steel Pipe and Galvanized Pipe

  • Steel pipe is made from iron ore that is melted in a blast furnace and then formed into a pipe.
  • Galvanized steel pipe is coated with zinc to help protect it from corrosion.
  • Steel pipe is available in a variety of different sizes and thicknesses.
  • Galvanized steel pipe is typically used for water supply lines, sprinkler systems, and natural gas lines.
  • Steel pipe is more susceptible to corrosion than galvanized steel pipe.
  • Galvanized steel pipe is more expensive than steel pipe.


When deciding between steel pipe and galvanized, consider where you will be using the piping and what conditions it will need to withstand over time. If you plan on using the piping outdoors or in any area prone to moisture, then galvanized pipe is probably your best bet due to its superior protection against corrosion and rusting. However, standard steel piping may suffice if your project isn’t exposed to moisture or extreme temperatures. No matter what your needs are, understanding the differences between these two types of piping will help you make an informed decision about which one is right for you!
