As you now know, galvanized and galvalume roofing materials have distinguishing characteristics and are not
interchangeable. So what are the main things to note about galvalume vs galvanized steel? Here are some key points.
Galvanized steel is made completely of zinc, while galvalume includes aluminum, zinc, and a small amount of silicon.
This provides superior durability and resistance to corrosion in comparison to galvanized coating.
Galvalume and galvanized steel are both made through a hot-dipping technique and have a similar thickness,
which is usually around 1 millimeter. This thickness may vary slightly from one material to the next, but if the
galvalume and galvanized steel coating are of the same thickness, the galvalume coating will usually last longer
than the galvanized coating.
As we’ve mentioned already, galvalume tends to last almost twice as long as galvanized steel before it shows any signs
of wear. This is mainly due to the aluminum that is added to the coating to prevent oxidation.
Thanks to its corrosion-resistant properties, galvalume is ideal for humid and hot environments, commercial buildings, residential homes, storage units, and more. Galvanized metal roofing is better suited for dry climates free of major
air pollution or pooling water.
Most steel roofing materials end up having some “edge creep” near the edges where the panel was cut. Fortunately,
galvalume is “self-healing,” meaning it eventually stops creeping and won’t spread rust all over the panel.
But galvanized steel is not self-healingthe edge creep rusting will only worsen over time.
Most galvalume roofing materials are included in a warranty, because they’re known for being durable and long-lasting. However, many galvanized materials do not have a warranty, since they can be unpredictable and unreliable,especially once they begin to rust.
Because galvanized and galvalume steel are made in a similar fashion, they’re sold at a similar price. All steel roofing is more expensive than asphalt shingles, but the long-lasting nature of the product means it is usually more cost-effective overall.
Galvalume is generally considered to be more favorable in appearance when compared to galvanized steel. The two coatings’ differences are subtle, but galvalume offers a smoother, matte appearance, while galvanized coating is more rough and shiny.
