Application |
| Regular Spangle |
Spangles condensated on zinc coating under normal conditions after galvanizing. |
Commercial purposes. |
| Mini Spangle |
Surface in spangles smaller than regular ones and due to controlled condensation of zinc coating. |
Applications where regular spangles cannot meet the surface appearance requirement. |
| Skin Passed Spangle |
Surface structure after special skin pass treatment. |
Applications of high surface quality requirements, such as color coating base plates. |
| Skin Passed and mini Spangle |
| Zero Spangle |
No visible spangles on coating surface as a result of a special production process. |
- |
| Zn-Fe Alloy |
No spangle, gray, normally matte. |
Applicable to further painting. |
