The name explains the look of the finish: these are well defined continuous uni-directional lines manufactured using abrasives that cut through the surface in microns. These differ from the #4 or Brush finish in surface roughness, grain structure and production methods.
The Hairline finish is a smoother, reflective finish and is used primarily as a decorative product visually when adjacent to polished stainless steel.
The texture of the surface varies with bead materials.
