If the operator is not familiar with the tendencies of aluminum, the material can crack or become deformed.
Many sports and entertainment arenas use curved aluminum for its lightweight and strength when making curved supports for overhead signage, display boards, and monitors.Ĭurving or rolling aluminum can be a little bit more difficult than curving or rolling normal carbon steel. Structural shapes can be rolled into rings for many uses, the corrosion resistance, as well as its strength-to-weight ratio, make aluminum rings very useful.
