Hot Dipped Galvanized Steel Sheet in Coil (GI) is produced by passing the Full Hard sheet which has undergone the acid washing process and rolling process through the zinc pot, thereby applying zinc film to the surface. It has excellent corrosion resistance, paintability, and workability due to Zinc’s characteristic. Usually hot dipped galvanized steel sheet and galvanized steel coil process and specifications are basically the same.
Hot-dip galvanizing is the process of applying a protective zinc coating to steel sheet or iron sheet, to prevent rusting.

The manufacturing of galvanized steel coil&sheet with good weather resistance, primarily used in construction.
Galvanized steel coils production process:
Use bending machine, pencil hardness tester, gloss meter, meteorologic tools, row lattice unit, micrometer tools, thickness gauge to control the quality of galvanized steel coil.
Packaging Details:
Hot Dipped Galvanized Steel Sheet in Coil is carbon steel sheet 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.
The prices of hot dipped galvanized steel coils depend on zinc thickness, steel coil thickness, packing method. If you want to buy cheap galvanized steel coils, please choose 20 grams of zinc coating/㎡, steel coil of 0.8mm thickness and simple packaging. please visit Color Coated Steel Coil Price: Factors Affecting.
