Corrugated Steel Sheets/Galvalume Coated Roofing Sheet/Galvalume Steel Corrugated Roofing Sheet

27 Mar.,2025

Galvalume combines three of the most high-performing and important metals used in roofing today — steel, aluminum, and zinc. Manufacturers begin with a cold-rolled carbon steel base sheet that is continuously hot-dipped with aluminum and zinc alloys (AZ) until it reaches a coating of 55% aluminum, 43.4% zinc, and 1.6% silicone.

Galvalume combines three of the most high-performing and important metals used in roofing today — steel, aluminum, and zinc. Manufacturers begin with a cold-rolled carbon steel base sheet that is continuously hot-dipped with aluminum and zinc alloys (AZ) until it reaches a coating of 55% aluminum, 43.4% zinc, and 1.6% silicone. 

 

Galvalume is suitable as a roof, wall, trim, accent, and more in most building applications in some of the most extreme environments, including non-coastal hurricane zones, locations with high rain or snowfall, high-temperature regions, and more.

 

Uses for galvalume corrugated roofing sheets:

 

Commercial building:Hospitals,schools,stores,government buildings,and others

 

Residential projects:Single-family, muliti-family,condominiums, and others

 

Architectural structures:Commercial, governmental, residential, and others

 

Structural or industrial applications:Warehouses, factories, and others

 

Agricultural:Non-animal confinement spaces, barns, storage, and others

 

Advantages & benefits of galvalume corrugated roofing sheets:

 

Crrosion resistance and self-healing properties

 

Galvalume’s chemical formula was specifically designed to combine the toughness, strength, and self-healing properties of zinc with the rust resisting properties of aluminum. That’s why galvalume’s corrosion resistance is about two to four times better than galvanized steel.

 

Galvalume’s self-healing characteristics help control the red rusting at any cut/exposed edges. Nearly all steel-based products will experience some level of normal edge creep from the exposed steel when the coil is cut, but it is minimal and will eventually stop with galvalume.

 

Easy to handle and install

 

Another benefit of galvalume is that it’s not as temperamental as other metals used in the roofing industry, like copper and zinc installers don’t have to worry as much about leaving fingerprints, deep scratches, etc., on panels because galvalume is tougher and a little more tolerable. It also doesn’t have many strict ventilation or air gap requirements like some other metals.

 

Longevity

 

Research indicated that galvalume roofing could last as long as 50+ years in the right environment without any extreme corrosion. This makes galvalume an excellent choice.
