HOT-DIP GALVANIZED STEEL SHEET (GI)

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.

DETAILS

The Quality Characteristics

Type Surface Conditions Characteristics Applications
Regular Spangle - Characteristics of crystal structure and unique gloss of   zinc due to the unrestricted growth of zinc crystals at   ambient temperature during normal solidification. - Better corrosion-resistant characteristics compared to   minimized-spangle and galvannealed steel sheet   without   painting. - Structural Materials Car Inner
- Lining and Bodies Home appliances
Minimized Spangle - Characteristics of the crystal structure due to the   restricted growth of zinc crystals during normal solidification - Good appearance after painting due to uniformity of the surface, and better paintability compared to regular   spangle - Furniture and Office
- Equipments Home Appliances
- Bass Materials for Painted Steel   Sheets
Zero Spangle - Difficult to check the crystal grains with naked eyes due to complete suppression of the growth of zinc crystals during solidification of molten zinc - Excellent appearance after painting due to the uniformity   of the surface and outstanding appearance - Furniture and Office
- Equipments Home Appliances
- Bass Materials for Painted Steel   Sheets
Extra Spangle - Extra smooth surface by temper rolling after the   solidification. Good appearance after painting due to   surface smoothness - Furniture and Office
- Equipments Home Appliances
- Bass Materials for Painted Steel   Sheets
