Bright steel bar is a carbon steel alloy which has had the surface condition improved by drawing, peeling or grinding over the hot rolled finish supplied by the steel mill. Advantages achieved include improved machining, less wastage at component production stage, enhancement of physical and mechanical properties and improved dimensional tolerances and straightness.

Hollow Bar or seamless mechanical tube as it is known, is a mechanical seamless hollow bar in heavy wall sections. The product has good machinability and weldability.
