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.
