Steel Angle vs Aluminum Angle

Steel Angle vs Aluminum Angle: What’s the Difference?

Before we get into the meat and potatoes of what differences there are between steel angle and aluminum angle, here’s a primer on the material.

Angle is a popular structural material that comes in an L-shape, created to offer better support in situations where two materials meet at a right angle. Due to its right angle, the angle is capable of bearing weight from the top or side regardless of the force that is applied. This makes for one of the most useful, yet versatile materials in not only steel but construction.

Now, as far as the differences between steel and aluminum angles, it comes down to how they are utilized as each has its pros and cons in certain situations. That said, here are some of the differences between steel and aluminum angles.

The Differences Between Steel Angle and Aluminum Angle

Rust

When it comes to rust, aluminum is superior to steel. Aluminum is far more rust-resistant than steel. This is due to steel’s carbon steel makeup as it is more prone to corrosion That said, while steel is more prone to corrosion, it is seen to have more weight-bearing strength.

Cold

Metals are known for becoming brittle when meeting extremely cold weather. Steel falls into this category. However, aluminum does not. Aluminum alloys are shown to maintain their ductility in frigid temperatures, which in turn combats any brittleness that may occur.

Everyday Life Uses

This is where we begin to see steel angle and aluminum angle on the same playing ground. This is mostly due to the ability for both to be used around the home for various projects. Some of these projects include bed frames, chairs, benches, support frames for air conditioning, and shelving, Both aluminum and steel angles can be utilized throughout these projects, but it ultimately comes down to weight, aesthetic, and whether it’s going to be indoor/outdoor. Whether you’re a professional handyman or just enjoy doing work around your home, these materials are a dream.

Weldability

If you need to weld angles together, steel is going to be your go-to. To preface this, aluminum is weldable, but you must be precise with how you do so. This is because aluminum angles provide much more room for error as it’s easier to cut/burn through. However, steel is more forgiving of a material. Its malleability makes welding steel angles, especially in construction projects, a no-brainer.

Decorative

Steel angles are seldom if ever, used in a decorative fashion. They are in most cases too thick to be displayed for anesthetic. Therefore, an aluminum angle will be utilized in this situation. Whether it’s for door frames or window frames, aluminum’s lightweight along with its ability to be easily cleaned make steel angle obsolete in this use. Also, while aluminum isn’t as thick, it still provides plenty of protection.

Fabrication

While angles are used primarily in support, they can also be used on their own. One of the most popular examples of this is creating grind bars for skating. While sparks are cool in photography and video, they do not offer the safest environment for anyone coming in contact with it. That is why grinding bars are primarily created out of aluminum angle rather than steel angle as aluminum does not spark.

Now that you’re more familiar with the difference in uses and properties between steel angle and aluminum angle, you can attack your next job or project with confidence.
