Gold Passivate commonly referred to as yellow or zinc plated.

A yellow plated zinc finish that provides a protective layer, providing a good level of corrosion prevention, as well as further protection due to the passivate addition which provides a yellow or gold finish.

Yellow Zinc (Gold Passivate) is the most common type of zinc plating used in automotive parts finishing. Gold is its colour only - it does not contain actual gold. Of all the zinc types it retains good average level of corrosion resistance

Blue or Clear Zinc (Silver Passivate) has no colour.

It is often referred to as blue as it can result in a blue-ish hue. The passivation of silver is a technical application for freshly silver plated surfaces. It is often achieved by tri-valent based processes which are more environmentally friendly than the hex-valent versions but offers lower corrosion resistant properties.

Black Zinc Plating

Black zinc plating is a popular choice for metal finishing due to its corrosion resistance and aesthetic appeal. This process involves coating the metal with a layer of zinc, which not only provides protection against rust and other forms of corrosion, but also gives the metal a sleek black finish. Whether you're looking to enhance the durability your metal parts or simply want to give them a stylish look, black zinc plating is definitely worth considering.

Zinc phosphate are mainly used for rust proofing on ferrous metals and is a chemical treatment applied to steel parts creating a thin adhering layer of iron.

Olive drab plating protects parts from corrosion. It involves applying zinc plating and a chromate coating for a durable, uniform finish that resists corrosion.

The Glass Shield process involves applying a clear liquid glass sealant over zinc plated parts to prolong their resistance to salt spray and overall lifespan. However, this finish is not appropriate for parts that require painting post plating, as the paint will not adhere to the liquid glass. Typically, this process is reserved for products exposed to outdoor elements.

Barrel plating is a form of electroplating used for plating a high volume of smaller metal objects. It consists of a non-conductive barrel-shaped cage in which the items are placed before being subjected to the chemical bath in which they become plated. Items include small components such as screws, nuts, bolts and washers. The barrel rotates slowly in the plating solution and offers a cost effective means of plating high volume parts.

Rack plating is a method used to electroplate large and complex parts that are difficult to plate using other processes. The parts are mounted to a fixture or jig known as a "rack" then immersed in a plating solution bath. This method is better for contours and intricate shapes and delicate parts that might not be able to withstand the tumbling action produced by barrel plating. The cost for this process is higher due to the increased labour requirements.
