Plate Polishing

When it comes to polishing stainless steel, we do it best.

Whether it’s your material, or material we source for you, we provide any and all finishes on stainless steel and stainless steel duplex alloys, stainless steel clad, Inconel and Hasteloy, to name just a few.
Whatever your finish needs, trust us to exceed your expectations.
We can provide all required finishes up to and including a 5 Ra maximum #7 PLUS “dull mirror” or “pre-buff”.

Plate Polishing Capabilities

  • Thickness‘ from .179″ up to 10″
  • Up to 14 feet wide and up to 46 feet maximum length
  • One or both sides polishing

Standard Finishes:

We can provide ANY specific Ra or grit finish – as fine as a 5 Ra dull mirror
We GUARANTEE not to exceed the maximum Ra required in any spot.

  • #3 60 Ra Max., Course satin appearance with parcel grain. “50 to 80 Grit”
  • #4 Architectural; 45 Ra Max., Refined and uniform satin appearance suitable for Ornamental Applications
  • #4 Process Surface; 30 Ra Max., Further refined “tighter-grain” appearance universally acceptable for process equipment systems and tanking wet surfaces. Meets most “dairy” and “Sanitary” application requirements. (See above Pit-free notation)
  • #6 Simulated-2B; 20 Ra Max., Fine grain satin appearance. Grain similar in surface roughness to 2B sheet. Chosen for minimized surface friction in powder and silo applications among others
  • #7 & #7 Plus; 9 or 5 Ra Max., Ultra fine highly reflective fine grain satin. Often used where mirror finishes are called for in non-ornamental applications as more cost effective.

All polished finishes include 100% of the HRAP surface “scale” removed to clean “parent” metal but not 100% Pit-free unless specifically requested. All finishes quoted as Maximum Ra taken in any spot. Never averaged.
