Hot-dipped Galvanized Steel Coils：
GI Steel Coils Introduction:
Hot-dip galvanized coil has the following characteristics:
First of all, the galvanized layer of hot-dip galvanized coil is uniform and strong, which can effectively protect the surface of the steel plate from corrosion.
Secondly, hot-dip galvanized coils are simple to manufacture, have high production efficiency and relatively low cost.
In addition, hot-dip galvanized coils are recyclable and environmentally friendly.
Galvanized sheets are actually cold-rolled sheets that are coated with a layer of zinc. In addition to cold-rolling lines, GNEE also has galvanizing lines, as well as pickling and baking.
The specific process flow is: hot-rolled plate-(after pickling) pickling plate-(passing rolling mill) cold-rolled plate-(passing hot-dip galvanizing) galvanized plate-(passing paint) color-coated plate.

Hdg coil classification, product range and properties:
Standards applied in different countries to set the requirements for hot dipped galvanized steel coils specify steel grade and size ranges for these products. Hot dipped galvanised coils are classified based on the following features:
● Application of coated steel (profiling, cold forming, manufacture of steel structures)
● Chemical composition of coating material (pure zinc, zinc-iron/zinc-aluminium/aluminium-zinc/zinc-magnesium alloys, etc)
● Thickness/weight of protective coating
●HDG coils according to European standards
