Hot rolled coils cleaned with acid are coated with zinc directly (GHR) or after cold rolling
(GCR) by continuous hot dip method in galvanizing line. Galvanized coating process is
applied to both surfaces; the upper and lower surfaces.
Galvanized materials produced with this coating process, which is realized to prevent
corrosion and increase the life of the material in areas exposed to the atmosphere, constitute the most important input of the automotive industry and the sectors that perform exterior
coating. Galvanized/galvanealed steels are passivated by chromating and / or oiling to
protect the zinc coating formed on the surface.
