Products Description
Spangle usually refers to the flash effect or silver light on the surface of galvanized steel plate in the metal material industry. It refers to the shiny pattern or texture formed on the surface of galvanized steel plate due to a specific galvanizing process. Spangle mainly appears on hot-dip galvanized steel plates.
The formation of Spangle is due to the cooling and solidification of molten zinc during galvanizing. Specifically, when the steel plate is immersed in molten zinc for hot dip galvanizing, zinc reacts with the surface of the steel plate to form an alloy layer of steel and zinc. During the solidification of the alloy layer, zinc crystals will form crystals with different sizes and shapes on the surface of the steel plate. These crystals are Spangle, and they reflect light, resulting in a shiny silvery white or gold effect on the surface of the steel plate.
The size and shape of Spangle will be influenced by many factors, including zinc plating process, composition of zinc liquid and surface state of steel plate. Common Spangle shapes include Regular Spangle, Irregular Spangle, Minimized Spangle and Normal Spangle. The existence of Spangle makes galvanized steel sheet have unique appearance characteristics, and also adds certain decorative effect to the product.
It should be noted that the formation of Spangle will not affect the corrosion resistance of galvanized steel sheet. However, in some applications, such as automobile outer panels or some precision equipment, it may be required that the surface of steel plate has a non-Spangle appearance, so we can choose products without Spangle or remove Spangle in subsequent processing.
