Patterns on Galvanized Steel: What are the Different Types?
The pattern we sometimes see on galvanized steel is called spangle. It used to be that nearly all hot-dipped galvanized steel was spangled. Spangling means that the steel had a pattern in the shape of snowflakes or six-sided stars that could be very clearly seen with the naked eye and viewed in detail under 10x … 展开
Spangling used to be so common that customers would assume that steel hadn’t really been galvanized if they couldn’t see the spangle. But, the … 展开
When spangling is aesthetically desirable, your galvanizer can get the same effect by adding environmentally-friendlier antimony to the molten zinc. Just 0.03 percent to 0.10 percent antimony in the molten zinc bath creates a coating that is smooth and shiny with barely … 展开
spangle “minimizing” device above the zinc bath. These devices directed steam or zinc dust at the surface to rapidly nucleate and freeze the zinc, essentially resulting in no spangle. The product …

What Is Spangle on Galvanized Steel? - wzppgi.com
Spangle is a unique and desirable feature that appears on galvanized steel during the hot-dipped galvanizing process. It occurs when liquid zinc cools and solidifies, resulting in crystal grains forming on the steel’s surface.
