Spangle is a surface morphology of hot-dip pure zinc coil. When the steel strip passes through the zinc pot, the surface is coated with liquid zinc, and then during the natural solidification of the zinc layer, the nucleation of zinc grains grows.
Aluminium has a density lower than those of other common metals, at approximately one third that of steel. It is one of the most common materials used in aerospace, medical, automotive and other industries because of its excellent strength-to-weight ratio
I like this natural color very much. Do you like it? After a busy work, it's really nice to go home and take a bath. It can temporarily forget all the trouble in the work and become refreshed.It's worth to try.
