Wall & roof panels offer the building user a choice of the best of exterior finishes: color coated panels or Galvalume, an aluminum/zinc alloy coated steel panel. Color finishes remain beautifully tough for years and years, and are available in a range of colors. These panels and color trim can be combined to provide a contrasting, or complementing, attractive appearance. Galvalume panels are formed of steel sheets that have a coating of about 65% aluminum and 35% zinc by volume. The result is a steel sheet that is highly corrosive resistant, offering the building owner the durability and long life of aluminum coatings and the galvanic protection of zinc coating.
