Hot-dip galvanizing (HDG) offers many advantages relative to other corrosion protection systems. HDG offers both barrier protection of the substrate and cathodic protection. No paint system can do that. Unlike paint, HDG is actually THICKER at edges and corners, where paint systems are most susceptible to failure. And HDG can protect nooks and crannies that paint just can't get to. Additionally, HDG is UV-resistant and is extremely durable. When applied to steel, HDG is actually harder than the steel substrate that it protects. Oh yes, let's not forget that HDG provides immediate protection when it comes out the vat. There's no need for the extended "curing" period required by many coating systems before the coated component can be placed into service.
In this course, you'll learn the mechanisms of steel corrosion and how HDG protects steel by providing both barrier and cathodic protection. We'll discuss the steps involved in HDG and how to prepare your assembly for HDG application. The course also looks at other methods for applying zinc to metallic components and how these alternate methods compare to HDG in both application and performance. Finally, we'll examine the superior durability and protection afforded by a duplex system, which contains a HDG base combined with a topcoat paint system.
Learning Objectives
