The biggest advantage of this alloy coating type, which has higher corrosion resistance than zinc plating and works with iron ions, is that the chromate layer covers the material homogeneously. This type of coating, which does not contain harmful wastes and has a uniform metal distribution, provides corrosion resistance according to the 480 hours (ISO 9227) salt test with a minimum coating thickness of 10 microns.
