What Is the Difference Between Galvanized and Galvalume?

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.

Chemical Makeup

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.

Thickness

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.

Longevity

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.

Uses

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.

Warranty

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.

Pricing

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.

Appearance

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.

Some regular usages: 

The product can be utilized in construction industry such as roof garage,and pipes, household electricity appliances

industry such as refrigerator's back plate, air conditioner; and microwaves, and automobile industry's gas vent, fuel tank etc.
