LONG TERM DURABILITY 

Galvalume® superior performance has been proven in the field. Over three decades of testing (one test ran for 20=years) has shown Galvalume® delivers superior corrosion resistance compared to Galvanized panels.In fact, Galvalume® performance in the construction industry has been so superior that steel mill warranty it against rupture, perforation or failure due to corrosion. Similar warranties do not exist for Galvanized.

LONG TERM TESTING 

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.

THE BENEFITS OF ALUMINUM AND ZINC  

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.
