Carbon Steel Bar
Carbon steel bars are available in round, square, flat, and hexagon bars in the hot rolled or cold drawn condition. While hot rolled and cold drawn bars have the same general shape, they are very different in their dimensional characteristics.
Hot Roll Bars – Produced on rolling mills that leave surface imperfections that include scale, seams, flat spots, ridges, etc.
Cold Drawn Bars – Hot rolled bars that have had secondary processes applied to improve the surface finish and to size the bar more precisely.
