Mechanical and Chemical Surface Treatments
- Buffed & burnished to a mirror like finish
- Abrasive blasted to a rough texture appearance
- Caustic Etch - uses a caustic solution to give a silver-white appearance
- Floride Etch - uses a fluoride solution to give a matte appearance
Bright Dip - polished first then chemical treated to yield a bright mirror like finish usually anodize afterwards to add a protective layer and/or add color
