Zinc, a bluish-white, lustrous metal, is one of the most often used metals in the electroplating industry.
Three J’s Industries uses an alkaline zinc plating bath. The resulting finish gives the steel part a corrosion protection coating as well as a nice bright appearance.
The alkaline zinc plating bath used by Three J’s Industries is exceptional because it is very ductile and has superior resistance to hydrogen embrittlement. Other types of zinc plating, like acid zinc, are not ductile and are very susceptible to hydrogen embrittlement. Alkaline zinc is the process most often used in the automotive industry, especially on safety parts.
Three J’s Industries electroplates parts with zinc in conformance with the most current specifications for a number of industry and OEM requirements.

Sophisticated and Flexible Production Lines
The modern processes and equipment at Three J's Industries are designed for the following reasons:
To consistently achieve the requirements of demanding specifications.
To provide flexibility in the production schedule in order to meet delivery commitments.
To maintain a clean operation necessary to minimize wastes and emissions.
Any size job from the smallest fastener to the largest stamping can be accommodated. The company has backup items on all equipment to ensure no downtime. A complete machine shop is located on site where equipment can be precisely fabricated and maintained for production.
Modern and Comprehensive Laboratory
With the instrumentation in its modern laboratory, Three J’s Industries has the capability of testing:
The plating thickness of parts by using a magna gauge, eddy current or x-ray machine.
Both plating baths for its proper chemical make-up by doing titrations daily.
The quality of its water with an atomic absorption spectroscopy machine.
In-house salt spray testing is available to ASTM B117
In addition to this laboratory equipment, Three J’s Industries has a Rockwell Hardness Tester and Comparator on site as reference tools for our customers.
Chemical Safety and Environmental Compliance
The processes and equipment at Three J’s Industries, Inc. are designed to ensure compliance with all applicable environmental regulations and permits. Our facility’s waste treatment was designed with piping overhead, rather than underground, so there is no danger of soil and groundwater contamination. Clean process operation minimizes wastes and emissions that could otherwise contaminate the environment.
