Finish Type |
Appearance |
Procedure |
Application |
DA Orbital |
Uniform small circular swirls |
Orbital sanding with 150 Grit pad to achieve 0.8RA finish |
USDA style hygiene Pre polish for bead blast, paint, powder coat, anodising etc |
Bead Blast |
Satin matt finish | Uniform finish applied by blasting with glass beads (Bead size/Ra reading to be specified) |
External of process equipment, Architectural, Complex shapes |
Rumbling |
Uniform, dull, edges | Parts are tumbled with ceramic stones | Uniform surfaces, broken edges, small parts, deburring |
DA Scotchbrite |
Uniform, low gloss. The most similar applied finish to 2B |
Orbital sander with scotchbrite pad | Where 2B is requested, but polishing is required |
Brushed |
Similar appearance to a No. 4 mill sheet. Applied by hand, so less uniform |
Uses 240 Grit and fine abrasives to produce short, coarse parallel polishing lines. All welds are ground and polished with a uniform grain finish |
Cabinets, large range of general items. Retail, Architectural |
Bristle Mop |
Semi mirror polish, small level of swirling |
Oil and Bristle mop | Kitchen benches, Dairy Tankers. Typically Architectural |
Electro Polish |
Reflective, high gloss with “orange peel” roughness. Likely to have fluid staining. Adds roughness to a BA finish |
An electrochemical process where the part is immersed in an electrolyte bath. This removes iron from the surface and enhances the chromium/nickel content, providing the most superior form of passivation for Stainless Steel |
Corrosion resistance, marine, surgical, bioprocessing |
Mirror Polish |
Highly reflective mirror finish similar to a BA mill sheet |
Multiple stages of polishing. Surface roughness better than 0.4Ra |
Decorative, Architectural, Pharmaceutical |

LOCAL BLAST |
Bead Blasted Weld Area | Bead blast minimum possible area to remove weld burn |
Most cost effective alternative to acid passivation |
STRIP BLAST |
Bead Blasted weld area with masked edges |
Bead blast weld area, plus surrounding area, up to sharp masked defined edges |
More cost effective alternative to acid passivation. |
Acid Clean and
|
Non uniform brushed finish |
Pickle/Passivate welds by applying acid, leave to soak then rinse with water and polish by hand with scotch brite to blend acid stain. A strip buff without masked edges will be used for long runs. |
Traditional basic weld finish |
STRIP BUFF |
Brushed/Buffed appearance with visible protruding weld bead and masked edges |
Passivate with acid, then buff over weld with 180 grit buffing wheel. |
External welds on tanks. More cost effective than acid & scotch brite for long runs |
STRIP POLISH |
Brushed weld area with no |
Remove weld bead by grinding and polishing to 0.8 Ra |
