When the hot dip galvanized sheets is pulled from the zinc pot, it will form the crystal appearance with the cooling of the zinc layers.
The principle is very clear. People try to decline the galvanize zinc’s temperature and prolong the spangles crystal’s producing time. The shorter the time is, the smaller the spangles is. The size, brightness and surface appearance are decided from a series of factors. But it main connects the zinc layers ingredient and cool method.
During the forming process of spangles, the technicist of CAMELSTEEL noticed that the main character of big spangles is that its thick middle part and thin edge. Even it is finishing, it is hard to make its surface smooth. Meanwhile, if the number is too much during the finishing, the forming property will decline. And it is hard to accept in the industries which has a high request of paintings’ quality and forming property.
With the development of the construction, industry and automobile field, no matter big spangle,small spangle or zero spangle, they all prompt the demand of galvanized steel coil rely on their unique appearance and excellent performance.
