Most are fabricated from high-strength steel or aluminium. Advanced composite materials may be used for lightweight applications in aerospace.
A 'beam' often implies a larger, more engineered structural component, while 'bar' might refer to a simpler, often solid piece. However, in rigging terminology, they are frequently synonymous.
