Looks and Quality that Make The Difference

Depending on your specifications, we can finish your products with low grit sanding to remove imperfections up to high grit to produce a near-polished finish.

Common Materials We Finish with Straightlining

  • Aluminum
  • Stainless steel
  • Bronze or brass alloys
  • Sheets and plates
  • 3-dimensional products

The metal finishing process is sometimes referred to as straight-line, stroke sanded, brushed, grained, or #4 finish.
