Zinc plating involves placing a coat (or plate) consisting of a thin layer of material—in this case zinc—over an object. In general, plating is used for protection against corrosion and, ultimately, making an object last longer. The benefits of zinc plating include superior adhesion and ductility, rust resistance and anti-corrosion properties in most atmospheres. Zinc plating is widely used on structural steelwork for bridges and buildings, in addition to items like nuts, bolts and screws.

As you seek information about zinc electroplating, consider whether your business can handle the job itself or whether your require the services of a company that specializes in zinc coating. If you require only occasional, small applications for zinc coatings, it may be cost effective to do the work yourself. But if you have larger-run needs, it's almost certainly most efficient to hire an expert. When thinking about zinc plating, consider the following:

1. Do you need mechanical zinc plating machines?

2. Do you require zinc plating kits and other supplies?

3. Do your needs suit the use of a company specialising in plating for zinc?

Action Steps
The best contacts and resources to help you get it done

Purchase a zinc plating process machine

Commercial zinc plating machines are available for your business, as are nearly-complete setups that are better suited to small- to medium-runs. Look for warranties on both new and used plating equipment, as well as distributors willing to help you with the setup process.

I recommend: Star Plater sells industrial plating systems. Walgren Company also offers commercial plating machines suitable for zinc plating.

Buy a zinc plating kit or other supplies

Once you have your machine, you must buy quality supplies to go with it. You may purchase kits that contain most of the supplies you'll need to create a zinc finish for small projects, or you can buy individual supplies in larger quantities.

I recommend: Eastwood Company sells zinc plating supplies, including kits, anodes and tints. Caswell offers zinc kits suitable for single items and very small runs. Electrochemical Products provides commercial zinc plating chemicals.

Seek out zinc plating specialists

For larger jobs, or when you simply don't want to expose your employees to hazardous materials, hire a company that knows all about zinc plating. Some will only take on large jobs, while others are better suited to small ones.

I recommend: Burbank Plating Service, in business since 1965, offers commercial zinc plating. Georgia Plating offers black zinc plating, as well as clear, olive and yellow electroplating. Monroe Plating does zinc plating of all sorts.

• •  Some items that are sold as 'galvanized' actually have zinc coatings. In most cases, zinc plating is used only on small items like bolts because such items need a finer finish than galvanizing can provide.
