Difference between Steel and Aluminum Beams

Difference in material properties

Steel beams are made of steel materials with good mechanical properties such as high strength, rigidity and toughness, which can meet the structural needs of large buildings.

Aluminum beams, on the other hand, are made of aluminum alloy, which is relatively low in strength but has good corrosion resistance and electrical conductivity, and is suitable for use in high humidity or acidic and alkaline environments.

Difference in weight

The density of aluminum beam is about 1/3 of that of steel beams, which means that aluminum beam are much lighter in weight, so they are used in some occasions with high weight requirements.
For example, if the overall weight of the building is required or if there is a need to increase the load on the original building structure, aluminum beams are a more suitable choice.

Difference in corrosion resistance

Aluminum beams are chemically stable in harsh environments and are therefore suitable for interior and exterior building decorations and finishes. They are also used in the production of marine shipping equipment, such as shipbuilding, garbage trucks, and offshore surveying equipment.
Steel beams, on the other hand, require anti-corrosion treatment on the surface to avoid corrosion and rust during their use.

Difference in construction cost

Aluminum beams are a bit more expensive than steel beams, but because of their light weight, they require relatively less labor and lifting equipment, which makes them less costly.
Steel beams, on the other hand, require relatively large labor and lifting costs due to their large weight, making them relatively costly.

In summary

Steel and aluminum beams differ in material properties, weight, corrosion resistance and construction costs. The choice of crossbeam material needs to be considered according to the specific needs and occasions, so as to achieve the best structural stability and cost-effectiveness.
