SECC Electro Galvanized Steel Sheet Zinc Coated Galvanized Sheet

Electrogalvanized Steel Sheet Characteristics:

Electro galvanized sheet is the name given to the process of applying a thin layer of zinc to the surface of a steel sheet. This process is used to prevent the sheet from rusting, increase corrosion resistance, and achieve an aesthetic appearance. The electro-galvanization process is carried out using electric current and is usually done through a process called cold rolling.

The steel substrate of the electro galvanized sheet is usually composed of a low-carbon steel, while zinc is used as the top layer. The zinc protects the steel while the steel substrate provides strength and durability. Electro galvanized sheet is used in many industrial applications such as roofing, automobile parts, water pipes, white goods, and many more.

This process should not be confused with hot-dip galvanization. In hot-dip galvanizing, the steel part is immersed in molten zinc and coated with zinc, while in electro galvanizing the zinc layer is drawn to the surface of the steel by electric current.

Electro Galvanized Steel Sheet Properties:

The mechanical properties of electrogalvanized sheet are approximately the same as those for the equivalent grade (steel designation) of cold rolled sheet because the steel coils are pre-annealed prior to processing on the electroplating line. For example, DDS cold rolled sheet and DDS electrogalvanized sheet have similar mechanical properties. This does not mean that electrogalvanized product will behave similarly during stamping/drawing. The coating influences the behavior during forming; thus, special practices are required when stamping electrogalvanized products. With the correct type of die material, clearances, etc., the stamping performance of the two products are similar.
