HOT-DIP GALVANIZED STEEL SHEET (GI)
Hot-dip galvanized steel sheets (GI) are 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. GI has a thicker galvanized layer which has excellent anti-corrosion qualities, and is the type of steel sheet most commonly used.
GI has excellent anti-corrosion, paintability, and processability due to the self-sacrificing characteristic of zinc.
It is available to select and produce the desired amount of zinc gilded, and in particular enables thick zinc layers.
It is classified as either zero spangle or extra smooth depending on whether the sheet undergoes skin pass treatment.
