The corrosive resistance of stainless steel comes from the transparent film of chromium oxide naturally present on the surface. The INCO colouring process involves submerging the stainless steel sheets in a chemical solution to thicken the chromium oxide layer and therefore create a colour effect via light reflection.
Although this layer is transparent, the colour effect is obtained when light is reflected off two different surfaces: the chromium oxide layer and the metal itself. This is similar to the effect of a rainbow and comparable to the colours of a film of petrol on water. The colour is determined by the thickness of this layer.
Advantages of this process:
We highly recommend that when installing any coloured sheets, you follow the direction of the arrows on the PVC protection to minimise differences in tonality. For exterior panels especially used for architecture and cladding, we can also discuss and determine specific colour parameters to suit your specific requirements.
