Why Zinc electroplating / galvanizing?
Zinc electroplating or electrogalvanizing dates back to the early 19th century when it was first discovered.
The electroplating of zinc gained popularity in the mid-1800s with the development of more efficient electroplating techniques and equipment.
Zinc electroplating was primarily used for decorative purposes, providing a shiny finish to metal objects.
However, as the understanding of its corrosion-resistant properties grew, zinc electroplating found widespread use in pretty much all industries. Protecting metal surfaces from rust and corrosion.
Over time, advancements in technology and environmental regulations have led to improvements in zinc electroplating processes, making them more efficient, environmentally friendly, and capable of meeting the evolving needs of various industries.
Zinc electroplating remains a vital surface finishing technique, offering both aesthetic appeal and robust protection for metal components in diverse applications.
Benefits of Zinc electroplating…
Zinc electroplating or galvanizing provides cost-effective and durable corrosion protection to your metal surfaces, enhancing their longevity and improving their aesthetic appeal.
Zinc electroplating offers…
- Cost effective
- Effective Corrosion Protection
- Enhanced Aesthetics
- Versatility in applications
- Affordable Surface Treatment with many different colours
Despite its protective qualities, zinc electroplating can introduce hydrogen into substrate metals, particularly in high tensile treated fasteners (8.8, 10.9 & 12.9) causing hydrogen embrittlement and compromising the mechanical strength.
Luckily, Team Plating Works have perfected a process in which hydrogen embrittlement does NOT occur.
This process is called Mechanical Plating and is offered here.

Blue Passivation
BLUE PASSIVATE brightens, passivates and protects the zinc from discolouration, and finger staining, and imparts added, corrosion protection. Zinc plated parts giving a minimum of 0.003″ of zinc will withstand 24 to 48 hours of salt spray after a treatment in BLUE PASSIVATE before the appearance of white corrosion products. Zinc plated parts with a minimum thickness of zinc of 10 microns should withstand salt spray testing ranging from 100 hours to 200 hours before the appearance of red rust.
Yellow Passivation
YELLOW PASSIVATE will produce a yellow colored, iridescent chromate conversion coating on zinc or cadmium. The film formed has excellent corrosion resistance and will meet all specifications calling for a yellow chromate which will withstand 140 hours salt spray. Zinc plated parts with a minimum thickness of zinc of 10 microns should withstand salt spray testing ranging from 250 hours to 500 hours before the appearance of red rust.
YELLOW PASSIVATE films also make an excellent base for the bonding of organic finishes.
Olive-Drab(Green)Passivation
Olive-Drab(Green)PASSIVATE produces a heavy olive drab chromate coating on zinc or cadmium plated surfaces.
Olive-Drab(Green)PASSIVATE provides the maximum salt spray and abrasion resistance of any type of chromate dip and is a satisfactory product for meeting Government specifications for this type of finish.
Olive-Drab(Green)PASSIVATE produces an excellent base for subsequent painting and can replace organic type primers for this purpose. The smooth glossy olive drab color produced by Olive Drab(Green)PASSIVATE is an outstanding final finish for many types of applications.
Olive-Drab(Green)PASSIVATE will withstand salt spray testing of 150 -225 hours before the appearance of white rust and 400 – 750 hours before the appearance of redrust.
Black Passivation
BLACK PASSIVATE produces a glossy or matte, black chromate conversion coating on zinc plate, zinc die casting or galvanized parts.
BLACK PASSIVATE provides an excellent base for subsequent paint, lacquer, or enamel finishes. Not recommended for outdoor purposes.
A bit of history on Black Japan
Japan black is a lacquer or varnish suitable for many substrates but known especially for its use on iron and steel. It is so named due to the history of black lacquer being associated in the West with products from Japan.
Its high bitumen content provides a protective finish that is durable and dries quickly. This allowed Japan Black to be used extensively in the production of automobiles in the early 20th century in the United States. It can also be called Japan Lacquer and Brunswick black. Used as a verb, Japan means “to finish in Japan Black.” Thus Japanning and Japanned are terms describing the process and its products.
Japan Black’s popularity was due in part to its durability as an automotive finish. However, it was the ability of Japan Black to dry quickly that made it a favorite of early mass-produced automobiles such as Henry Ford’s Model T. The Ford company’s reliance on Japan Black led Henry Ford to quip “Any customer can have a car painted any colour that he wants so long as it is black”.
The development of quick-drying nitrocellulose lacquers (pyroxylins) which could be colored to suit the needs of the buying public in the 1920s led to the disuse of Black Japan by the end of the 1920s. Today the name is still know and used but as an alternative Black Passivated Zinc is used by us to produce the black finish required.
