American Galvanizers Association

The American Galvanizers Association (AGA) is a non-profit trade association dedicated to serving the needs of after-fabrication galvanizers, fabricators, specifiers, architects, engineers, and contractors. The AGA provides technical support on today's innovative applications and state-of-the-art technological developments in hot-dip galvanizing for corrosion control. The AGA also provides a number of services to galvanizers and zinc producers in the industry. The AGA celebrates 85 years of preserving the past, enhancing the present, and protecting the future.

Preparing HDG Surfaces for Paint or Powder Coatings

The ASTM specifications D6386 and D7803 which cover preparing the hot-dip galvanized surface for paint and powder coating, respectively,also reference SSPC surface preparation standards. Here is a list and brief summary of the surface preparation standards used in the hot-dip galvanizing industry.

Dissimilar Metals in Contact

When two different metals are in contact in a corrosive environment, one of the metals experiences accelerated galvanic corrosion while the other metal remains galvanically protected. Metals near each other in the galvanic series have little effect on each other. Generally, as the separation between metals in the series increases, the corroding effect on the metal higher in the series increases as well.

How Long Does HDG Last?

Hot-dip galvanizing (HDG) is often used to protect steel from corrosion in some of the harshest environments imaginable, yet it provides maintenance-free longevity for decades. Find out how long galvanized steel will last in your application.
