The process of bathing a metal surface in hot zinc heated to 860 degrees fahrenheit is called galvanized plating. Galvanized plating, often referred to as hot-dip galvanizing, has been used for decades in rust resistance since zinc can halt many forms of corrosion and is insoluble in water. Automotive manufacturers often use the galvanizing process on exterior body panels, but the galvanizing process is also used as a protective layer on wrought-iron fences, hand rails and other metal objects that are regularly exposed to the elements.

To make the right choice when it comes to finding the right protective coating for your products, consider the following:

1. Online directories for finding different processes and profiles

2. Professional galvanizing services

3. Alternatives to professional, hot-dip galvanizers

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

Consult online directories to find a galvanizing service near you

You can find a galvanizing service through online industrial service directories. Whether you only need galvanizing or extras like rust removal, welding or inspection, service directories can get you company portfolios and contact information as well as the ability to find a service in your area.

I recommend: Peruse more than 170 galvanizing services through ThomasNet. Register with GlobalSpec to find more than 1,300 coating service companies.

Contact high-capacity galvanizing companies for a professional job

Reliable galvanizing companies will offer a multitude of coatings as well as computer-aided equipment for the most professional spray techniques. You should also look for a galvanizing company that uses reduced-friction and non-stick coatings.

I recommend: Metal Coatings Corp. can handle jobs up to 40,000 pounds and offers next-day emergency services. Aztec Galvanizing Services also offers professional hot-dip services and has plants in 20 different locations across the U.S..

Find cold galvanizing products for an alternative to hot-dip galvanizing

If you have access to a galvanizing plant and are looking to buy a solid galvanizing coat for either hot dip galvanizing or cold galvanizing -- the process of painting with zinc-rich paint -- you can find the widest variety of products online. You can also find products for galvanizing touch ups if you want to stretch the life of what you've already galvanized. Look for sites that have built-in website tools or customer service contacts to make sure you get the right cold coating for your application.

I recommend: ZRC Worldwide offers products made specifically for cold galvanizing. Tessco also offers products for cold galvanizing, as well as products for touching up hot-dip galvanized surfaces.

Tips & Tactics

Helpful advice for making the most of this Guide

• •  Ask any professional galvanizing company about their drying process. A white 'rust' can form on newly galvanized products that are bundled too tightly. The rust prevents a film from forming on the zinc surface. The rust doesn't necessarily compromise the coating's stability but will prevent a shiny, metallic appearance.
