How customers usually run this
Galvalume is ideal for atmospheric-corrosion-critical outdoor parts. Avoid contact with copper, treated lumber, and wet concrete (galvanic and alkaline attack). For long-life unpainted roofing, specify AZ55. For coastal applications, ask us about painted Galvalume instead.
