Galvanized Steel Sheet has two kinds of zinc stripes, one is normal stripe and the other is zinc-free stripe. In the previous galvanized sheet, because the lead in the zinc solution cannot be extracted purely, there will always be some spangles on the surface, so the well-known galvanized steel sheet is generally considered to have spangles.
With more and more applications of galvanized steel sheet in the automobile industry, when spraying automobiles, it is harmful to spray galvanized steel sheet with spangle, so people start to widely manufacture galvanized steel sheet without spangle.
Spangle-free galvanized steel sheet According to the production process, the lead in it is manipulated to a certain level in the zinc pot, or after the hot-rolled steel sheet leaves the zinc pot, it is uniquely resolved, such as a small spangle treatment process or spraying zinc powder, Enables the spangle to be manipulated below a certain level to obtain a spangle-free commodity.
The key to galvanized steel sheet is to further process the pure zinc product with zinc non-ferrous metal solution after leaving the zinc pot to obtain galvanized steel sheet without spangle, dark gray and matt.
