Electro Galvanizing (EG)
Electro galvanizing otherwise known as electro-plating, is a process that uses DC current to deposit a zinc coating on steel parts. A zinc Anode (+) is placed in a solution that is referred to as an electrolyte, typically Zinc sulfate or Zinc Chloride. The steel part receiving the zinc acts as a Cathode (-). When the steel part acting as the cathode is immersed in the electrolyte the zinc anode oxidizes and the electrolyte carrying the DC current between the Anode and cathode carries the zinc from thee anode to cathode (steel part, nail or wire). The amount of zinc deposit on the cathode (nail), is controlled by the time the part is in the electrolyte along with amount of current that is applied.
Hot Dipped Galvanized (HDG)
Hot-dip galvanizing, as referenced, is the process of dipping steel (Nails) into a kettle or vat of molten zinc. While the steel is in the kettle, the iron metallurgically reacts with the molten zinc to form a tightly-bonded coating of zinc.
Mechanical Galvanizing (MG)
Mechanical, also known as peen plating, , is a plating process that imparts the coating by cold welding fine metal particles to a work piece (Nail). The process involves tumbling the work pieces with a mixture of water, metal powder, media, and additives.
