Aluminum has many advantages over steel for certain applications. This is particularly true when you consider safety, speed of installation and material fatigue. Aluminum doesn’t rust like steel does, which means it won’t corrode and weaken during use. It also weighs less than steel by about half, so it’s faster to install and requires less reinforcement in the structure as well. The fact that aluminum can be formed into practically any shape also makes it ideal for some applications where traditional materials like concrete or wood simply aren’t an option. 

It is lighter weight than steel, which makes it faster to install and reduces the need to raise specific weight tolerances 

Aluminum is lighter than steel, which means it takes less energy to transport and install. For example, if you change the weight of your car by just 50 lbs (23 kg), you can get a 3% increase in fuel efficiency. That’s because less mass requires less force to move through space, and thus requires less power from an engine. This principle also applies on a larger scale when considering the transportation of materials like aluminum beams or panels—the reduction in total weight allows for more efficient use of fuel resources. 

The reduced weight also makes it easier to handle these materials safely while they’re being installed into structures where they will be required to perform their function safely over time. The forces involved are significant: one hundred pounds (45 kg) exerts approximately 1 tonne per square foot (t/m2). The fact that these lightweight materials are easier to handle decreases risk of injury among workers handling them during installation or maintenance work over time 

Extrusions can be formed into practically any shapes. 

You can have your aluminum extrusion shaped into whatever you want. Not just rectangles and squares, but also complex shapes like circles, triangles and polygons. This is called the “extruder” part of extrusion manufacturing because it turns out to be possible for aluminum extrusions to exist in a variety of forms. 

In addition to making things easier on the people who make them and install them, this flexibility also makes it possible for these materials to be used as structural components in buildings and other structures that need loads bearing down upon them with weighty force (such as bridges). It’s not just that they’re strong enough; they’re also lighter than steel—and therefore easier on materials costs when used over large areas like rooftops or floors. In fact, some manufacturers claim that up to 80% less material is needed compared with similar-sized beams made from steel! 

Aluminum is leading the way as a structural material of choice. 

Aluminum is a great choice for structural applications because it’s lightweight, corrosion resistant and recyclable. It can be formed into shapes that make it easy to work with and structurally strong—making it a top-notch material when you’re building bridges or other structures that require extra strength. 

Aluminum has been used in structures for decades because of its ability to deliver superior performance at a lower weight than steel. This makes aluminum more environmentally friendly than steel, which requires more energy (and therefore emits more carbon dioxide) during production than does aluminum. Plus, aluminum can be recycled endlessly without losing any strength properties, making it an excellent choice for sustainable design projects like stadiums or houses that need to stand up through decades of use without becoming obsolete before their time! 

When you consider everything from corrosion resistance to weight, aluminum has many advantages over steel for certain applications. 

What do you think of when you hear the words “aluminum” and “steel”? Perhaps you picture a lightweight, malleable material that’s easy to bend into shapes. And you’d be right to do so—a good chunk of the world’s aluminum is used in construction applications like framing and cladding. But those are just some of its uses: Aluminum is also used in things like cars, planes and boats, as well as consumer products like soda cans (and even beer bottles). 

Aluminum’s strength versus weight ratio is another factor worth considering before committing to building with it: Aluminum is stronger than steel but weighs less per cubic foot! That means that you’ll need less material for an aluminum structure compared with a similar-strength steel structure; which could save both time and money during construction efforts! 

Corrosion resistant 

Aluminum is a naturally corrosion resistant material, which means it doesn’t corrode easily. This makes aluminum a good choice for many structural applications, as it can withstand high levels of moisture and other corrosive elements. 

When aluminium becomes exposed to air, however, it will develop an oxide layer on its surface that protects the metal from further oxidation. If this oxide layer is damaged or removed in any way—for example by mechanical abrasion or through exposure to certain chemicals—the metal will begin to oxidize at an accelerated rate. To combat this problem and make it even more corrosion-resistant than usual, aluminium can be coated with anodizing solutions or polymer coatings (such as polytetrafluoroethylene) that form a continuous barrier around the metal surface. 

Aluminium does not rust like steel does; instead it forms a protective coating known as mill scale when exposed to damp environments over time. 


Aluminium is lighter than steel, by a lot. This is a major advantage in applications where weight is an issue. The industry refers to this property as “strength-to-weight ratio.” For example, if you had two pieces of metal and one of them weighed half as much as the other, you could use it in a situation where your design called for twice as much strength—and have less material to work with. 

One good example where lightweighting can be beneficial is aerospace construction. The space industry has strict FAA requirements around how much each component needs to weigh; they’re limited by how much fuel they can carry into orbit and back down again (or not). Using high-strength aluminium alloys like AA7075 or even 2024 T3 allows designers to build stronger structures that weigh less and meet their structural requirements at the same time—which translates into lower shipping costs since there’s less mass being lifted by rockets (and therefore more cargo room). 

Long life cycle 

Aluminum is a very durable material. It has a long life cycle, and it’s resistant to corrosion. That means it can last for many years without losing its original strength or shape. 

It’s also recyclable, so when aluminum does eventually need replacing, you won’t have to worry about waste disposal—you can simply melt down the old item and remake something else from it! 

Preassembly capabilities 

Preassembly is a booming business in the aluminum industry. With preassembled parts, you can ship aluminum frames and connectors that are ready to be bolted together once they reach their final destination. This saves time and money, as well as reducing the need for skilled labour. 

You may be wondering why this is such a big deal. Well, steel isn’t so easy to work with when it comes to preassembly: at least two workers need to be involved in order for any assembly of structural steel components (beams, columns) occur—one worker will hold up one component while another worker secures it into place with bolts or welds; this process repeats itself until everything has been assembled correctly. The key difference here is that there needs to be an extra person holding each component up prior to assembly; otherwise things could fall apart during installation (which would cause serious injury). 

The problem with this method is that adding an extra person increases costs considerably; workers also require training before they begin working on sites where these parts are being used because safety precautions must always be taken into consideration first when dealing with heavy machinery like cranes or forklifts! 

It’s made in Canada – with hydroelectrically powered plants 

If you check the back of your aluminum cans, you’ll find the country of origin listed as Canada. This is no accident: Canada’s aluminium production is the best environmental choice, thanks to its hydroelectrically powered plants. In fact, Canada has the largest aluminium industry in the world and produces around 20% of global output. 

The electricity generated at hydroelectric plants comes from water flowing through dams on rivers—in other words, it’s a clean, renewable source of power that doesn’t pollute our air or harm wildlife. 


So, if you’re considering a steel structure, think again. Aluminum is the way to go!
