The procedure
Electrochemical process: a computer-controlled electrochemical process; no color or pigments \u2013 coat of lacquer or any other coating as well – are applied, the transparent chromium oxide layer is built up.<\/p>\n\n\n\n

Interference effect: The interference effect is used; depending on the thickness of the applied chromium oxide layer, the composition of the light spectrum and the angle of view, different colour effects develop.<\/p>\n\n\n\n

Stainless steel character: Due to the small thickness of the chromium oxide layer, the structure of the colored surfaces has an undiminished effect; retained are not only the functional material properties, but also the optical quality inherent in the stainless steel.<\/p>\n\n\n\n

Resistance of colored stainless steel surfaces<\/p>\n\n\n\n

Corrosion resistance: The corrosion resistance<\/strong> of the basic material used is decisive. Although the chromium oxide layer built up during the colouring process is an improvement from corrosion-technical view, in principle a material quality<\/strong> is to be chosen according to the expectable strain.<\/p>\n\n\n\n

Resistance to light, weathering and aging: Coloured stainless steel surfaces<\/strong>, do not age, they do not get chapped, do not bleach and do not peel off.<\/p>\n\n\n\n

Temperature resistance<\/strong>: The coloured surface<\/strong> is resistant to temperatures up to 200 \u00b0 Celsius<\/strong>. Short-term exceeding of temperature of about 100\u00b0 Celsius can generally be endured, but persistent discolourations occur during continuous exceedances.<\/p>\n\n\n\n

Mechanical resistance<\/strong>: The chromium oxide layer built during coloring<\/strong> is organically bonded with the base material and is elastic. Deformations (bending, edging, pressure forming and deep drawing)<\/strong>, which do not affect the basic material itself, do not damage the surface. The resistance<\/strong> to abrasive stress is limited due to the low layer thickness<\/strong> of the interference film<\/strong>.<\/p>\n\n\n\n
