Standard to Mirror Finish

Brighton Tru-Edge manufacturers the highest quality polished heads in the industry. We can achieve a near mirror finish or produce a standard uniform finish, depending on our customers’ specifications. Our experienced team utilizes best-in-class equipment to spin polish heads as large as 252″ in diameter. A tracking mechanism follows the contour of the head for a smooth transition from the dish radius into the knuckle portion of the head.


Our proven track record of delivering superior polished finishes includes heads across a variety of industries, including:

  • Food & Beverage
  • Chemical Processing
  • Pharmaceutical
  • Architectural
  • Bioprocessing

Miller Mechanical 280297 007Surface Finish Ratings

Historically, surface finishes were described using polish numbers, such as a #4 or #7. In some cases a grit finish was used, which is not a measurable standard. At Brighton Tru-Edge, we utilize the Roughness Average (RA) to deliver precise and consistent results. The RA is expressed in microinches and our quality assurance team measures it using a profilometer.

RA Equivalents

  • #4 polish = 25 RA maximum
  • #7 polish = 10 RA maximum
