Cold rolled coil refers to the steel coil obtained after rolling by cold rolling machine, or called cold hard coil. In practice, we usually after cold rolling and the next process of the steel coil is called cold rolling.
Galvanized coil is cold rolled after the cold hard coil as raw material, after alkali washing, annealing, galvanized, leveling steel coil. Usually also called cold rolled galvanized coil.

What Is Hot Dipped Galvanized Steel
Hot Dipped Galvanized Steel Sheet in Coil is cold rolled steel coil coated with zinc on two sides by a continuous hot-dip process. This method tightly adheres the coating to the steel with an iron-zinc alloy bonding layer formed by a diffusion process while the heated steel strip is in contact with the molten zinc. One of the drawbacks of Galvanized is that if the Zinc coating is scratched off the steel, the Steel is left unprotected, and is subject to failure.

Galvanized Steel Coil Could Be Oiled?

Yes, it could be oiled. 8-20g per square meters. Oiling can prevent the oxidation of galvanized sheets in a short time.
