Galvalume roll jacketing outlasts regular galvanized steel in marine salt spray and industrial atmospheres for a longer lasting installation. Since it can be used at temperatures up to 600°F (315°C)withoutdiscoloration, and up to 1250°F (677°C) without heavy oxidation or scaling, it provides superior fire resistance and protection compared to aluminum.The special alloy coating of aluminum and zinc combines the best properties of both metals; it has the corrosion resistance, high temperature oxidation resistance, and heat reflectivity of aluminum with the formability and galvanic protection of cut edges characteristic of zinc.
