Is Galvalume Steel really much better than galvanized sheet metal?
DEFINITELY. The Galvalume Steel that the buildings are made from is from Bethlehem Steel in the United States (Bethlehem, PA). It’s first quality American Steel. 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 20 years against rust and corrosion.
