SPCC Cold Rolled Galvanized Steel In Coil Oiled and Unoiled
Treatment Surface
1. Introduction
Hot-dipped galvanized steel coil is produced through a
preocess of metal coating which involves passing cold rolled coils
through a kettle containing molten zinc. This process ensures
adhesion of zinc to the surface of the steel sheet. The zinc layer
provides excellent corrosion resistance and prolong service life.
Galvanized products are widely used in household appliances,
transport, container manufacturing, roofing, base material for
pre-painting, ducting and other construction related applications.
