CMPI was born to offer plate and sheet polishing services to other manufacturers, serving both the numerous stainless steel fabricators in the local area and beyond. As CMPI has grown, the demand for our brand of plate polishing has increased dramatically. We attribute our success in the industry to our organization's rigorous quality standards. 

From 20 gauge to 3/4" thickness, one side or both, we are confident that our high grade polishing services will meet and exceed your expectations, because our standards are your exact specifications.

  • CMPI Standard Polish is with hold-downs, there is a 3/8" to 1/2" maximum on one end and 1 3/4" to 3" maximum on the other end left unpolished.
  • CMPI Tab Polish provides polishing to approximately 3/8" (+/- 1/4") on each end with some possible distortion from weld on tabs. Available in thicknesses 14 gauge and thicker.
  • CMPI Full Sheet/Plate Polish requires material at least 3" longer than actual required finished length. This is accomplished by polishing longer material and shearing off approximately 3" from the overall length (determined after polishing).
