Sheet Bar
Sheet Bar
a flat steel billet 4–22 mm thick and approximately 150–730 mm wide, produced by section and billet mills and in tended for hot-rolling into sheets 0.18–3.0 mm thick. It is used in the production of steel plate, dynamo and transformer steel, roofing iron, and steel sheet, as well as skelp for welded pipe. Sheet bar is hot-rolled on two-high mills (sometimes by pack rolling) or on sheet-bar billet mills. The length of a sheet bar depends on the desired width of the finished steel sheet or the length of the longest billet that can be heated in a continuous (holding) furnace before rolling on a skelp mill.
