Technical Library – American Galvanizers Association
Galvan Industries is a member of the American Galvanizers Association. As the non-profit trade association for the batch hot-dip galvanizing industry, the AGA produces and maintains a wide variety of detailed technical publications about hot-dip galvanizing. The association has over 40 publications available to download free of charge on its web site, www.galvanizeit.org. All the publications are regularly reviewed and updated to keep the information fresh and at the forefront of galvanizing technology. A single copy of a publication is available at no charge, unless otherwise indicated.
Hot-Dip Galvanizing Costs Less, Lasts Longer
When selecting a corrosion protection system for a given project, it is paramount to consider more than just the initial cost. Taking into account the life-cycle cost of maintaining a corrosion protection system provides a more accurate prediction of the project’s impact on future generations.

FREQUENTLY ASKED QUESTIONS
Metals in contact with HDG
The hot-dip galvanized coating is primarily comprised of zinc and zinc alloys and is sometimes placed in contact with different metals. This creates the possibility for galvanic corrosion that depends on the position of the other metal relative to zinc in the galvanic series, and to a lesser degree on the relative size of the surface area of the two metals in contact.
Can you paint over HDG?
Though many specifiers are familiar with specifying one type of corrosion protection or another, few realize the intrinsic value of utilizing two corrosion protection systems together, known as a duplex system. A duplex system is formed by painting or powder coating over hot- dip galvanized steel.
Our in-person Galvanize It! seminar is the best way to earn free CEU’s and learn about hot-dip galvanizing because you can meet with a galvanizing representative face-to-face who will address any questions or concerns immediately. Sign up for a seminar to be presented at your office and lunch is on us!
The AGA’s Galvanize It! seminar series is also offered as a webinar presented by an AGA staff member. Webinar attendees will learn about the various aspects of hot-dip galvanizing followed by live Q&A to answer specific questions. All webinar versions are approved for 1.0 LUs (HSW) / PDH through AIA and RCEP.
The AGA has created an online, on-demand inspection course that will train individuals on the proper inspection techniques and requirements for hot-dip galvanized steel products. Anyone who completes the course, and passes the test (80% or better) will receive a printable Certificate of Completion and will be listed on the AGA website.
Hot-Dip Galvanized Steel vs. Paint
This handout is a detailed cost comparison of hot-dip galvanizing and paint. The handout features a side-by-side comparison of weather dependency, bond strength, service life, and much more. It also compares the initial cost and maintenance cost of hot-dip galvanizing with 4 paint systems.
Hot-Dip Galvanized Steel vs. Weathering Steel
This one-page handout provides a side-by-side comparison of hot-dip galvanized steel and weathering steel. The analysis includes fatigue life, inspection, appearance, corrosion rate, and much more. In addition, the handout explains the performance of both steels in five different environmental conditions.
