Surface finish guide for machined and sheet metal parts

Why finishing matters

Surface finishing can affect corrosion behavior, wear, friction, electrical contact, appearance and assembly performance.

Buyer checklist

  • Define whether the finish is cosmetic, protective or functional.
  • Mark masked surfaces, threads and electrical contact areas.
  • Confirm color, texture and inspection expectations where appearance matters.

Common routes

Common options include as-machined, bead blasting, anodizing, passivation, plating, powder coating and polishing. Final availability depends on material and geometry.
