Home / Mill Surface Defects / Flow Lines (Galvanize Defect)
What is it?
Similar to flow line on galvannealed materials, this defect gives the coil a sagging appearance across the full width of the coil. It is caused due to differences between the strip temperature and the zinc bath, which result from delayed solidification of the zinc on the surface of the steel.
