Hot-dip galvanized Steel or GI is produced by coating iron and steel with zinc, which alloys with the surface of the base metal when immersing the metal in a bath of molten zinc at a temperature of around 449 °C (840 °F). When exposed to the atmosphere, the pure zinc (Zn) reacts with oxygen (O2) to form zinc oxide (ZnO), which further reacts with carbon dioxide (CO2) to form zinc carbonate (ZnCO3), a usually dull grey, fairly strong material that protects the steel underneath from further corrosion in many circumstances.

A spangle is the visible aesthetic feature of crystallites on the surface of a galvanized Steel Sheet. The spangle appears as either a snowflake or a six-pointed star pattern. This is produced on the steel sheet when certain alloying elements are either added to the liquid zinc or available as impurities.
The size and orientation of the zinc grain affects the corrosion and mechanical properties of the zinc alloy. This can be altered by alloying elements such as:
· Lead
· Aluminum
· Antimony
· Bismuth
· Tin
Spangles give the zinc coating a decorative appearance determined by orientations of the zinc crystals and the distribution of the alloying elements in the coating.
The Gi coil is devided into Big、medium、small and zero spangle. Nowadays, the Galvanized Steel Coil without Spangle with Zero Spangle is the most popular galvanized hot dipped steel.
