Polishing
An abrasive finishing process that uses progressively finer abrasive compounds or buffing wheels to reduce surface roughness and increase surface reflectivity. Polishing grades range from satin (400 to 800 grit) to mirror finishes (2000 grit and above).
Polishing is the premium finishing technique for achieving mirror-bright or satin finishes on decorative stainless steel, aluminum, and brass components where visual appeal is paramount. The process uses progressively finer abrasive compounds and buffing wheels, typically starting at 120 to 220 grit for initial smoothing, progressing through 400 to 800 grit for satin finishes, and reaching 1500+ grit for mirror-polished results that rival jewelry.
Each abrasive stage removes the scratches from the previous, coarser stage, so skipping intermediate grits wastes labor and material. High-quality buffing compounds tailored to your specific metal type are essential, using the wrong compound may smear instead of remove surface material, creating a hazy appearance rather than clarity.
For architectural and decorative fabrications, polishing combined with passivation (for stainless) creates finishes so elegant they often require no further coating, eliminating the need for powder coating or paint.
