Q:How does the size of the zinc spangles on the surface of galvanized steel affect its performance?

The size of the zinc spangles on galvanized steel strip primarily affects its appearance and some performance.
In terms of surface properties, the size of the zinc spangles directly determines the material's appearance and suitability for subsequent processing. Galvanized steel strip with large zinc spangles has noticeable zinc spangles and a rougher appearance, creating a unique decorative effect. However, due to its slightly less flat surface, applications requiring spraying or lamination require additional polishing, which can affect coating adhesion.

Galvanized steel strip with small or no zinc spangles has a smoother surface and relatively better corrosion resistance. This is because there are fewer gaps between the zinc spangles, reducing the chance of corrosive media intrusion.
