Aluzinc Steel Coil Strip AZ150 Aluzinc Coated Steel Coils Gl Galvalume Steel Coil

Aluzinc steel refers to 55% Al-Zn coated steel products, which is also called galvalume steel.

Aluzinc steel is well suited for roofing and siding applications, as well as automotive, home

appliances, furniture, etc. Due to its versatility, durability, beautiful appearance, aluzinc steel

is favored broadly.

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

GL 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 ga

-lvanized 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, GL 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.

Ability to Self-Heal

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.

Appearance

GL 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.
