In bright bar we can offer a variety of products from Round Bright Bars, Square Bright Bars, Flat Bright Bars, and Hexagonal Bright Bars. Bright Bars are steel or metal bars that are produced by one or more cold finishing processes. The processes outlined below are known as Cold Finish processes or the end products are known as cold finished because there is no or very little heat applied in the entire operation of converting them from hot rolled bars (also known as black bars) to Cold Finished Bars or Bright Steel Bars.
