What is the difference between a steel and aluminum tube?


Tubes made of steel are stronger and stiffer. For this reason, steel tubes are often used for structures that are exposed to heavy loads and characterized by larger spans. Due to their industrial nature and resistance to scratches, steel tubes are also often used in the manufacture of furniture. Their disadvantage as compared to aluminum tubes is that steel is much heavier. Aluminium tubes are often used for advertising structures. This is to avoid adding up unnecessary load.
