Electrical galvanized steel is made by plating steel with zinc in an electrochemical manner. Plating uses pure zinc or zinc and nickel.

KS & JIS Specifications
Two types of zinc coating weights?the same weight on both sides and differentiated weights on each side?are applied to the steel sheets and steel coils. The standard and minimum Zn coating weights are marked with a code combining the coating weight of each side. The marking methods are as follows.
When attaching a label indicating an application of “differentiated coating weights” on two sides of the steel sheets or coils, a letter “D” is written after the minimum coating weight code on the surface with the label. (e.g., E8/E16D)
|Zn Coating Weight Code||Minimum Zn Coating Weight (One Side)||Standard Coating Weight||Corresponding Zinc Thickness (mm) / One Side|
|Both-Sided Coating||Differential Galvanizing|
|Category||Minimum Value (3) Points||Minimum Value (1) Points|
|Coating Weight (Both Sides)||Coating Weight (Both Sides)|
