Our product portfolio also includes electrolytically galvanized steel. The soft grades DC01 to DC07 and the micro-alloyed grades HC180Y to HC420LA are incorporated under this designation. Electrolytic galvanized steel is a high quality steel with a coating that is applied by an electrolytic process and firmly adheres to the base material. The electrolytic coating not only provides excellent protection against corrosion, it is also a primer for subsequent coatings.

The type of surface treatment is named with the following code letters.
