During the galvanization process, steel sheets or zinc steel coils undergo a treatment that applies a protective zinc coating to the surface, resulting in galvanized steel strips. This process creates a barrier between the steel and the surrounding environment, preventing corrosive substances from reaching the underlying steel. The zinc coating forms a sacrificial layer, shielding the steel from corrosion and extending its lifespan significantly.
Surface Difference of Zero Spangle & Regular Spangle
There are many factors affecting the size of zinc spangles. When the zinc liquid composition has the conditions for the formation of zinc spangles, the following factors will affect the size of zinc spangles:
1) Raw material: the smaller surface roughness, the thicker raw material steel plate, the bigger zinc spangle.
2) Cooling rate: the faster cooling rate, the shorter crystal growth time, the smaller zinc spangle.
3) Number of crystal nuclei: The size of zinc spangle is closely related to the number of crystal nuclei of zinc spangle. When the surface of steel base is rough or the surface cleanliness is poor, the zinc spangle is relatively small. Zinc grains are formed on steel base, and the more nuclei there is, the smaller zinc spangle will be. This principle is used in the production process of zero zinc spangles.
4) Other factors, for example, production environment, factory machines and etc..
