| Hot Rolling Blooms, billets, or slabs are heated above the critical range and rolled into a variety of shapes of uniform cross section. The more common of these rolled shapes are sheet bars, channels, angles, and I-beams. Sheet bar and rods rolled from steel are used extensively in aircraft work. Hot-rolled material is frequently finished by cold rolling or drawing to obtain accurate finish dimensions and a bright, smooth surface.
