Galvanized steel Coil/Sheet (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.

Hot-dip galvanizing is the process of applying a protective zinc coating to steel or iron, to prevent rusting.

  • Excellent anti-corrosion, paintability, and processability due to the self-sacrificing characterisiticof zinc.
  • Available to select and produce the desired amount of zinc gilded and in particula enables thick zinc layers(maximum 600g/m2).
  • Classified as either zero spangle or extra smooth depending on wheteher the sheet undergoes skin pass treatment.

Packing Detail

Packaging Details:

  1. Each bare coil to be securely tied with two bands through the eye of coil (or not) and one circumferential.
  2. the contact points of these bands on the coil edge to be protect with edge protectors.
  3. Coil then to be properly wrapped with water proof /resistant paper, it then to be properly and completely metal wrapped.
  4. Wooden and iron pallet can be used or as your requirements.
  5. And each packed coil to be properly wrapped with band, three-six such band through the eye of coil at about equal distance.

Galvanized FAQ

What is Galvanized Steel

Galvanized Sheet 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.

Galvanized Steel Coils Prices

The prices of 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.
