The Challenge of Finding AZ150 Galvalume Steel Sheet
Many buyers ask: how do I source reliable AZ150 Galvalume Steel Sheet? Suppliers vary in quality, certification, and price. Without ASTM A792 certification, you risk inferior coating performance. Thus the problem: ensuring both material integrity and supplier credibility. In my early days in procurement, I once received sheets that corroded in weeks—costly lesson learned firsthand.
Solution Framework
We propose a three-pillar solution:
-
Verify ASTM A792 certification.
-
Evaluate coating weight and adhesion.
-
Partner with proven suppliers (e.g. Shanxi Luokaiwei Steel Company).
By following these steps, you ensure true AZ150 performance (150 g/m² coating) and long-term durability.

Understanding ASTM A792 & AZ150
ASTM A792 defines chemical and mechanical requirements for Galvalume steel. AZ150 indicates 150 g/m² minimum aluminum-zinc coating. This delivers up to 60% better corrosion resistance than standard galvanized sheet (AZ150 vs. Z275).
Comparative Analysis: AZ150 vs. Z275
| Feature | AZ150 Galvalume Sheet | Z275 Galvanized Sheet |
|---|---|---|
| Coating mass (g/m²) | ≥150 | ≈275 zinc only |
| Corrosion resistance | High (≤1 µm/year loss) | Medium (≤2.5 µm/year) |
| Lifespan (outdoor) | 25–30 years | 15–20 years |
| Price index (100=base) | 120 | 100 |
Step-by-Step Procurement Guide
-
Define specs: AZ150, sheet thickness, length.
-
Request ASTM A792 MTRs from suppliers.
-
Inspect sample coating weight in lab.
-
Verify adhesion via bend test.
-
Check delivery lead time and logistics.
-
Finalize contract with quality clauses.
⚠：Common Misconceptions
-
Believing any “galvanized” label equals AZ150.
-
Skipping MTR review—dangerous.
-
Ignoring supplier track record.
Case Study—Roofing Project in Guangzhou
Problem: Early roof panels rusted in 2 years.
Solution: Switched to AZ150 Galvalume from Shanxi Luokaiwei.
Result: Zero corrosion over 5 years, saved 18% maintenance cost.
