Galvalume Steel Panels

Galvalume Steel Panels

Galvalume steel panels were created back in the late 1960s to elevate the substrate formulation for metal roofing. Steel panels will rust quickly without a layer of protective coating. Before galvalume was invented, contractors commonly used galvanized steel panels for metal roofing. Galvanized metal panels are created by hot-dipping steel into zinc. Zinc serves as a protective layer to prevent rusting. Zinc does a great job of protecting the steel, but the formulation needed something to diminish premature corrosion. To extend the durability characteristic of metal roofing, galvalume was created!

What is galvalume?

Galvalume was created to take metal roofing to new heights. Both metal panels—galvanized and galvalume—are created with a hot-dipped coating process. Galvanized steel is hot dipped in 100% zinc. To further extend metal roofing’s protective properties a new formulation was created. This is called galvalume. Galvalume is dipped in a combination of the metal alloys—zinc and aluminum. The ratios of the coating are 55% aluminum to 45% zinc. The corrosive resistance rate of galvalume steel panels has proven to be twice as effective in performance as galvanized steel. Metal roofs are known to be one of the best roofing materials on the market. The creation of galvalume—by adding aluminum to the coating formulation—has substantially improved metal roofing longevity characteristics.

Unique characteristics of Galvalume

You may be wondering. How does adding one simple metal alloy to the coating transform the steel roofing panel? Adding aluminum to the coating tremendously impacts the oxidation process as a roof faces Mother Nature over its lifespan. The aluminum and zinc combination act as a self-healing mechanism for the roof. Zinc will help the panel self-heal from scratches, and aluminum puts a halt to the spread of corrosion and rust. Consider this analogy to understand how galvalume works. When you get a cut on your skin, a scab appears, and then your skin self-heals the wound. Studies have shown—for this reason alone—galvalume is the superior substrate for long-term protection compared to galvanized steel.

Ideal applications vs. impractical applications

Metal roofing has proven itself to be one of the most durable, long-lasting, sustainable roofing materials available on the market. Despite its tremendous properties, it’s not practical in all geographic locations. One setting you want to stray away from when using galvalume is animal confinement buildings. The manure will break down into ammonia gas. This does not react well with the galvalume coating formula. Galvalume steel panels are also impractical for coastal environments. Metal roofs of any substrate formulation do not perform well in this atmosphere. Sodium chloride does not react well with metal roofing panels, and they will deteriorate much more rapidly than their life expectancy should be. Other than animal confinement and coastal environments—Glvalume is a superb roofing option! Galvalume steel panels can be used for residential, commercial, and industrial applications. Would you choose Glvalume for your roof?
