AZ50 galvalume steel is produced using a hot-dip coating process to coat steel with a 55% aluminum-zinc alloy. It offers excellent corrosion resistance, heat resistance, strength, and formability. It is widely used in roofing, wall cladding, home appliances, and industrial buildings. Wanzhi Group supplies AZ50 galvalume steel coils, sheets, strips, and roofing products with customized grades, thicknesses, widths, and sizes.
- Thickness: 0.12-3.0mm
- Width: 600mm-1,250 mm
- Standard: ASTM, EN, JIS, GB
What Does AZ50 Galvalume Steel Mean?
AZ50 Galvalume Steel refers to steel with an aluminum-zinc alloy coating. AZ50 indicates a total coating weight of 0.50 oz/ft², equivalent to approximately 150 g/m² on both sides of the sheet. The coating typically contains about 55% aluminum, 43.5% zinc, and 1.5% silicon. A higher AZ designation generally indicates a higher coating weight, while the Al-Zn coating provides excellent corrosion and heat resistance. Wanzhi Group supplies galvalume steel with AZ30–AZ150 g/m² coating weights for different applications.

AZ50 vs AZ55 Galvalume Steel
AZ50 and AZ55 galvalume steel both use a 55% aluminum-zinc coating. The main difference is the total coating weight, with AZ55 having a slightly higher coating mass, which may provide additional coating protection where a higher coating mass is specified.
| Item | AZ50 Galvalume Steel | AZ55 Galvalume Steel |
| Coating Designation | AZ50 | AZ55 |
| Total Coating Weight | 0.50 oz/ft² | 0.55 oz/ft² |
| Approx. Metric Coating Mass | 150 g/m² | 165 g/m² |
| Al-Zn Coating | 55% Al-Zn | 55% Al-Zn |
| Corrosion Protection | Good | Slightly higher |
