EC Williams brings you an efficient, precise and cost effective zinc electroplating service.

The majority of our zinc plating at EC Williams is for the automotive industry. We work to OEM and international specifications for our zinc plating process. Additionally, we pride ourselves on our range of post-plating treatments. These include: chromate passivate in trivalent clear and black, as well as yellow.

Ever since yellow passivate has been banned by environmental legislation, because it contains hexavalent chromium, many manufacturers have missed the well-known colour passivate.

It clearly showed that the parts had been passivated and offered a colour differentiator, where components were difficult to visually distinguish.

We are now pleased to be able to offer a trivalent yellow passivate which meets the environmental legislation, and is a good yellow colour.

Offering up to 120 hours to white corrosion resistance it is an important addition to our range of passivates. They now include the aforementioned colours, in addition to olive drab green, and blue dye.

We are exacting in our controlled deposit thickness and have the capabilities to zinc plate onto most substrates. Including; copper, phosphor bronze, brass, steel and zinc die-casts.
