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, paint ability, and work  ability 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, paint ability, and process ability 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:13 years in heavy industrial areas,50 years in the ocean,104 years in the suburbs and 30 years in cities.

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.

Product Introduction

Hot-dip galvanizing is the reaction of molten metal with an iron substrate to produce an alloy layer, thereby combining the substrate and the plating layer. Hot-dip galvanizing is to pickle iron and steel parts first. In order to remove iron oxide on the surface of iron and steel parts, after pickling, it is cleaned in an ammonium chloride or zinc chloride aqueous solution or a mixed solution of ammonium chloride and zinc chloride.And then sent to the hot-dip plating bath. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion and long service life.
