Galvanized vs Galvalume
Side-by-side view of Galvanized (GP/GI) and Galvalume (GL/AZ) for roofing and cladding decisions.
| Aspect | Galvanized (GP/GI) | Galvalume (GL / AZ) |
|---|---|---|
| Coating type | Primarily zinc hot-dip coating | Aluminum-zinc alloy coating |
| Corrosion performance | Strong general corrosion protection in many applications | Often better long-term atmospheric corrosion performance in many roofing environments |
| Heat reflectivity | Standard roof thermal behavior | Typically better reflectivity due to aluminum-rich coating characteristics |
| Typical use | General fabrication, roofing, and utility sections | Roofing, cladding, and building envelopes where longer-life coated performance is targeted |
| Best when you need | Traditional GP route and mainstream project procurement | GL/AZ route for long-life roofing and cladding requirements |
Frequently Asked Questions
Key Galvalume questions from roofing buyers and project teams.
What is Galvalume?
Galvalume is steel coated with an aluminum-zinc alloy (commonly called GL/AZ). It combines aluminum’s barrier behavior with zinc’s sacrificial protection, making it a common choice for roofing and cladding.
What is Galvalume made of?
Galvalume is a steel base with an aluminum-zinc alloy coating. Commercial supply is booked by coating class (for example AZ25 to AZ150) and thickness according to project requirements.
What is Galvalume roofing (or Galvalume roof)?
Galvalume roofing is roofing sheet/profile made from GL/AZ coated steel. It is widely used for industrial sheds, warehouses, and commercial roofs due to durability and practical lifecycle value.
How long does Galvalume last?
Service life depends on environment, coating class, profile design, and maintenance. In many projects, Galvalume provides long-term performance, but exact life should be judged by site conditions and specification.
How to clean a Galvalume metal roof?
Use low-pressure water and mild non-abrasive detergent, then rinse thoroughly. Avoid harsh chemicals and abrasive tools; always follow installer/manufacturer maintenance guidance for your specific roof system.
How much is Galvalume per foot?
There is no single fixed per-foot price. Cost depends on thickness, coating class (AZ), profile, quantity, and origin. Share your exact specification and we can quote current market rates.
