Material surface finishing problem
++++
I am from the metal industry and i am facing problems with the
Material surface finishing problems listed below: - Galvanize Iron
1) Black patches with looks like oil stain which is unremovable
from the material surface.
2) material discoloration near both edges of the coil
- sometimes the edge surface is brighter than the center portion of
the material surface.
- sometimes the edges are darker or black.
3) Intermittent black lines running along the coil surface.
