Rare metal surface

Stainless steel oxidation coloring (Rare metal color)

By controlling oxidation film thickness of stainless steel, colored surface caused by light interference is now newly introduced.

Stainless Steel grating used to involve the image of clean, high grade, and the design impression. On the other hand, it looks same and bored.

Rare metal, oxidation film treated, can cover the image of warm and soft without loosing the existing strength and contribute for the environment.

Oxidation film treatment is effective for the corrosion resistance.

Color Variation (Printed colors are slightly different from original colors)

※Only black is available in case of welding type.

Main feature of Rare Metal

  1. Gloss and coloring can be maintained for a long time, since this coloring is not coated, no color fading occurs on the surface.
  2. This product is sustainable even outside. This sustainability keeps the metal surface glossy, together with the capability of corrosion and weathering resistance, if properly maintained condition.
  3. Different from coatings or pigment over the steel, oxidation film treating is feasible to recycle with other materials. This treating can contribute for our better environment.
Diagram of light interference through material film layer

Reflecting light is caused by the two layers. On the top of stainless layer, oxidation film layer causes light interference and looks like colored. (Please see reference diagram in the left.)

Since the thickness of oxidation film is very thin, stainless material quality can be maintained without loosing the peculiar coloring of this product.
