Difference between Aluminum and Galvanized Steel

It’s important to understand the difference between aluminum and galvanized steel when you are choosing materials for your project. Both of these materials have their own unique benefits and drawbacks, so it’s important to choose the right one for your needs. In this blog post, we will take a closer look at both aluminum and galvanized steel, and we will help you decide which one is best for your project. Stay tuned!

What is Aluminum?

  • Aluminum is an abundant metallic chemical element with the symbol Al and atomic number 13. Aluminum is silvery-white, soft, nonmagnetic, and ductile metal in the boron group. By mass, aluminum makes up about 8% of Earth’s crust; it is the third most abundant element after oxygen and silicon. Aluminum metal is so chemically reactive that native specimens are rare and limited to extremely reduced or isolated compounds. Instead, it is found combined in over 270 different minerals.
  • The chief ore of aluminum is bauxite. Aluminum was synthesized by Hans Christian Orsted in 1825 in an impure form but it wasn’t until 1886 that commercial production began. Today, aluminum’s uses have expanded far beyond its roles as a structural material. It is now employed in packaging, transportation, building and construction, electronics, aerospace, and other industries.
  • Aluminum’s properties of being lightweight yet strong makes it ideal for many applications. It can be drawn into wire and made into a foil for wrapping food because it reflects heat and light very well. Aluminum foil can also be used as an electrical conductor when electrodes are placed on either side of the foil for electrolytic processes such as plating metals onto foil.

What is Galvanized Steel?

Galvanized steel is a type of steel that has been coated with a thin layer of zinc. This protects the steel from corrosion and gives it a more durable surface. Galvanized steel is often used in construction, especially for roofing and framing. It is also a common material for pipes and other types of tubing. Galvanized steel is an affordable option for many projects, and it can be found at most hardware stores.

Difference between Aluminum and Galvanized Steel

Aluminum and galvanized steel are both popular materials for a variety of applications, but there are some key differences between them. Aluminum is a lightweight metal that is highly resistant to corrosion. Galvanized steel is made by coating a layer of zinc on top of steel, which helps to protect the underlying metal from rust and corrosion. Both aluminum and galvanized steel are durable and long-lasting, but galvanized steel may be more suitable for certain applications due to its corrosion-resistant properties.


Although aluminum and galvanized steel are both great materials for roofing, they each have their own unique benefits. Aluminum is a lightweight material that can be easily installed, and it doesn’t corrode or rust. Galvanized steel is stronger and more durable than aluminum, making it a good option for areas that experience high winds or extreme weather conditions.
