Is Galvalume Steel really that much better than galvanized sheet metal?
ABSOLUTELY! It really is. The Galvalume Steel that we buy is from Bethlehem Steel right here in the United States (Bethlehem, PA). It’s first quality American Steel (not imported lower grade quality). The Galvalume has an aluminum-silicon-zinc alloy that is applied to the steel with a continuous hot dip process. This gives the steel a light dove gray sheen that carries a steel-mill backed guarantee for 25 years against rust and corrosion.
