Aluminum sections can be thinner since they do not lose strength due to corrosion.

27

Is very lightweight material, hence aluminum girders and columns show increased efficiency with large bay spacing. However, because the modulus of elasticity of aluminum alloys is lower than steel, its means that buckling is a possibility and should always be checked.
