(1) A semi finished section hot rolled from a metal ingot, with a rectangular cross section usually ranging from 16 to 36 in., the width being less than twice the thickness. Where the cross section exceeds 36 in., the term ?bloom? is properly but not universally used. Sizes smaller than 16 in. are usually termed ?bars?; a solid semi finished round or square product which has been hot worked by forging, rolling, or extrusion. (2) A semi finished, cogged, hot rolled or continuous cast metal product of uniform section, usually rectangular with radiused corners. Billets are relatively larger than bars.
