Aluminum profiles have proven to be just some of the most useful materials in construction, industrial, and other residential applications. One of the main drivers behind this is that these profiles largely take advantage of the various properties of aluminum. This particular alloy is a versatile material that has a high resistance against corrosion, lightweight, low-density, machinable, smooth, and malleable. 

They are used for structural purposes in different construction, architectural and industrial settings.

In conclusion, while steel is generally stronger than iron, both metals have their own unique advantages and disadvantages. Steel is preferred for its superior strength, durability, and resistance to corrosion, making it a versatile and widely used material in various industries. On the other hand, iron still has its place in certain applications where its unique properties, such as ductility and wear resistance, are more desirable.
