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
characteristics. 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 a steel sheet or iron sheet,
to prevent rusting.
* Excellent anti-corrosion, paintability, and processability due to the self-sacrificing characteristic of zinc.
* Available to select and produce the desired amount of zinc gilded and in particular enables thick zinc
layers(maximum 120g/m2).
* Classified as either zero spangle or extra smooth depending on whether the sheet undergoes skin
pass treatment.

Product Advantages
01.Anticorrosive: 15 years in heavy industrial areas,
02.Cheap:The cost of hot-dip galvanizing is lower than that of other coatings.
03.Reliable:The zinc coating is metallurgically bonded to the steel and forms part of the steel surface,so the coating is more durable.
04.Strong toughness:The galvanized layer forms a special metallurgical structure that can withstand mechanical damage during transportation and use.
05.Comprehensive protection:Every part of the plated piece can be galvanized,and is fully protected even in depressions,sharp corners,and hidden places.
06.Save time and energy:Galvanizing process is faster than other coating methods.
