Panels and other components for iron and steel buildings often have a zinc coating to protect them from oxidation that leads to corrosion. However, there is an alternative coating material that plays a vital role in preserving the aesthetics and structural integrity of such materials. In this blog, we discuss everything you need to know about Galvalume®.
What Is Galvalume®?
Galvalume is a thin, corrosion-resistant coating applied to raw steel materials and components through a continuous hot-dip process similar to galvanization. Once the base material is coated with this material, expect it to be impervious to the ill-effects of water and other substances that promote oxidation that leads to corrosion.
What Makes Galvalume Stand Out From Competitors?
Both coatings sacrifice themselves to protect the base material they cover. The way they do this, however, affects their lifespan and structural integrity. Galvanized steel features 100% zinc while Galvalume consists of 50% zinc, 50% aluminum and trace amounts of silicon. Coated steel components may still corrode, but Galvalume does a better job at slowing down the spread of corrosion throughout the material. Once galvanized steel oxidizes and corrodes, the coating can’t keep it from spreading, causing it to lose its structural integrity.
Which Metal Types Can Be Applied With Galvalume?
Many metal materials can benefit from a Galvalume coating, especially those that can be galvanized. Examples include carbon steel, cast iron and low alloy steels. Outdoor metal panels and metal roofs are among the most popular applications of Galvalume coatings because of their superior resistance to corrosion in outdoor environments. These materials and components are capable of withstanding corrosion when exposed to rain, ice and snow.
