What is Zinc Yellow Chromate Plated Steel?

Zinc yellow chromate plated steel, often referred to as ‘yellow zinc plating’ or ‘chromate conversion coating’ on zinc, is a steel substrate that has undergone an electroplating process with a layer of zinc, followed by a chromate conversion coating. The zinc layer provides sacrificial cathodic protection; meaning, if the coating is scratched and the steel is exposed, the zinc will corrode preferentially to the steel, preventing rust formation. The subsequent yellow chromate layer significantly enhances this corrosion resistance and provides a distinctive bright yellow or iridescent finish. This dual protection makes it a popular choice for components exposed to moderate environmental conditions. The steel itself can range from carbon steel to alloy steel, depending on the intended application and required mechanical properties. For Rotterdam’s maritime and industrial sectors, this level of protection is invaluable, mitigating the effects of salt spray and atmospheric corrosion common in coastal regions of the Netherlands.

The electroplating process involves immersing the steel parts in an electrolytic bath containing zinc ions. An electric current is passed through the bath, causing the zinc to deposit evenly onto the steel surface. Following the zinc plating, the parts are dipped into a chromate solution. This chemical reaction forms a thin, passive chromate film on the surface of the zinc. The ‘yellow’ color comes from the specific types of chromates used, which often contain trivalent or hexavalent chromium compounds, resulting in the characteristic golden-yellow hue. While hexavalent chromium offers superior corrosion resistance, environmental regulations in the Netherlands and across the EU are increasingly favoring trivalent chromium alternatives due to health and safety concerns. Therefore, understanding the specific type of chromate used is important for compliance and performance.
