A bright bar is a stainless steel bar supplied with a relatively clean and smooth processed surface compared with a conventional hot-rolled black bar.
Bright describes a processed bar surface commonly produced by drawing, peeling or related finishing, while polishing is an additional surface-finishing operation used to improve smoothness and appearance.
Yes. Centerless grinding can be reviewed for applications requiring tighter diameter control and a consistent finished surface.
Yes. Diameter, tolerance, straightness, finished length and surface condition can be reviewed according to production route and machining requirements.
Yes. Third-party testing can be coordinated when required. The TÜV Rheinland report shown on this page is an actual tensile-test record for a tested 316 stainless steel bar sample.
