Galvalume® offers proven long-term performance in the field. With over 30 years of testing, Galvalume® has demonstrated outstanding corrosion resistance compared to galvanized steel. Its performance has been so reliable that many steel mills provide warranties against rupture, perforation, or corrosion-related failure — warranties that are not typically offered for galvanized products.
In an extended test, unpainted Galvalume® and galvanized panels were placed in four outdoor environments, including marine and rural locations. The results showed that the more aggressive the environment, the better Galvalume® performed. After 23 years of side-by-side exposure, Galvalume® was shown to be two to four times more durable than galvanized steel.

Galvalume® is made from a patented alloy of corrosion-resistant aluminum and zinc, giving it unmatched durability. Most Galvalume® substrates consist of 55% aluminum, 43.5% zinc, and 1.5% silicon, a composition proven to outperform traditional galvanized coatings in corrosion resistance.
This advanced coating allows Galvalume® steel roofs to last longer, require less maintenance, and provide superior value over time. These properties make Galvalume® an excellent alternative to traditional roofing materials. Today, Galvalume® is used in more than 40 billion square feet of roofing worldwide, protecting buildings of nearly every type.
