Choosing the right finish
No.4 and Hairline are the workhorse decorative finishes for elevators, home appliances and architectural panels. Scotch-Brite gives a soft, uniform, non-directional surface. BA 4K/6K builds a mirror on bright-annealed base material, and 8K is the maximum-reflectivity mirror for high-end decoration.
