Applied finish examples

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

Acid Dip

Uniform low sheen
finish
Pickled by complete immersion in Acid
Solution
Higher quantities,
uniform finish across
weld and surface

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
Scotch Brite

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
visible weld bead

Remove weld bead by grinding
and polishing to 0.8 Ra
