In one test, unpainted Galvalume® and Galvaized Panels were placed in four different types of outdoor environments, including normal marine and a rural setting. The harsher the surroundings, the better Galvalume® performed. After 23 years in side-by-side comparison in all areas, Galvalume® was two four times more durable than Galvanized.
Galvalume® 26 GA Grade 80 – Grade E Coil Side 43”
Galvalume® 26 GA Grade 50 – Grade D Coil Side 41.5”
Galvalume® 24 GA Grade 50 – Grade D Coil Side 42.75”
A patented alloy of barrier-resistant aluminum and corrosion fighting zinc gives Galvalume® it’s superior corrosion resistance. Most Galvalume® substrates feature an alloy that is 55% aluminum, 43.5% zinc and 1.5% silicon. Test have proven this alloy superior to the zinc-only coating used in regular galvanized sheeting. Time has proven that Galvalume® steel roofs last longer, require less maintenance, and offer exception-al value. It’s this combination that has made Galvalume® steel roofing the ideal alternative to traditional non-metallic roof systems. In fact, Galvalume® steel roofing now totals over 40 billion square feet worldwide, covering buildings of almost every type.
