Which term refers to a hot-rolled steel member used as a primary support in bridges?

Explanation:
A rolled beam refers to a hot-rolled steel member used as the primary load-carrying element in bridges. These beams, typically in I-beam or wide-flange shapes, are formed by hot-rolling steel to produce efficient cross-sections with high moment of inertia, which helps them resist bending from deck loads and transfer forces to supports. In bridge construction, rolled beams act as girders or main supports spanning between piers and abutments, carrying the vertical loads safely. Rivet is a fastener used to join members; Screed is a tool for leveling concrete; Scuppers are openings to drain water. These serve different roles and are not the primary load-bearing members in a bridge.
