In general, Z stands for pure zinc coating and ZF refers to zinc-iron alloy coating. The number represents the thickness of the zinc layer. For example, Z120 or Z12 means the weight of zinc coating (double-sided) per square meter is 120 grams. While the zinc coating of the single side will be 60 g/㎡. Below is the recommended zinc layer thickness for different use environments.
| Z10 or Z12 (100 g/㎡or 120 g/㎡) | |
| Z20 and painted (200 g/㎡) | |
| Z27 (270 g/㎡) or G90 (American Standard) and painted | |
| Thicker than Z27 (270 g/㎡) or G90 (American Standard) and painted | |
| Thinner than Z27 (270 g/㎡) or G90 (American Standard) to avoid coating peeling off after stamping |
