Surface Treatment of hot dip galvanized steel coil

There are many surface treatment processes for galvanized steel coil, and the surface treatment requirements are different according to different uses. The following are common surface treatments,

Hot-dip coated flat products receive one of the following surface treatments at the producer’s plant :
chemical passivation: C
oiling: O
chemical passivation and oiling CO

The period of protection afforded is limited and depends on the atmospheric and storage conditions.
Hot-dip coated flat products are only supplied without surface treatment (untreated (U)) if expressively desired bythe purchaser on his own responsibility. in this case, there is increased risk of formation of corrosion products onthe surface during storage and transportation.

Chemical passivation, Oiling treatment, Skin-pass, Chromate, Unoiled, Dry etc.
