Black oxide coating

Black oxide coating of steel produces a very thin, durable and impressive finish. The technical coating is black in colour.

Thanks to the chemical treatment, black oxide coating penetrates evenly into the surface of the piece. Black oxide coating improves the visual appearance, properties and corrosion protection of the surface-treated part. The pieces are oiled at the end of the treatment. This oiling increases the corrosion resistance of the blackening. The treatment is done by rack or barrel coating methods in automated lines.

Maximum size of the piece to be coated

  • maximum length 800 mm
  • maximum width 250 mm
  • maximum height 500 mm
  • maximum weight 25 kg
