Electro Galvanized Steel

Electro galvanized steel, also known as electroplated steel, is produced through an electrochemical process that deposits a thin layer of zinc onto the surface of a steel substrate. This zinc coating provides corrosion resistance to the underlying steel and enhances its aesthetic appearance. The electroplating process involves immersing the steel substrate in an electrolyte solution containing zinc ions and passing an electric current through it to deposit the zinc onto the surface.

The difference between EG and HDG

  • For hot dip galvanization, a very rigid cleaning process is followed, which is generally known as the 7 bath process. Cleaning is done in alkaline solution, pickling, water rinsing, fluxing. In case, of EG, there is not followed stringent cleaning method.
  • Steel is said to be dipped in molten zinc bath @ 460 degree Celsius to achieve the coat for hot dip galvanization. But in the latter, steel is prepared in cathode in electrolytic cell, thus forming coating using electroplating process.
  • Hot dip galvanization produces on steel surface Fe-Zn alloy layer, leaving behind pure zinc coating on outer surface. This alloy is quite hard. Damage is not caused to the coating by the usual abrasion, even though some damage may take place to the pure soft zinc present at the top. Electro galvanization produces Zn layer on surface that is termed to be not continuous with that of steel metallurgically.
  • EGhas very low life, ranging from several months to some years only. But, hot dip galvanization is known to have very high life averaging between 20 to 50 years.
  • EGcomes with excellent finish. However, hot dip galvanization has dull, unpleasant finish.
  • The coating thickness of hot dip galvanization generally is about 80-100 µm. The coating thickness entirely depends upon the dipping duration. Also, it is affected by the steel’s roughness and composition. For EG, coating thickness generally is about 10 to 12 µm. here, the coating thickness is determined upon the electrolyte temperature and current density.
  • Hot dip galvanization is said to have normal coat thickness of about 40% much more expensive when compared to EG. The latter has normal coat thickness that is much affordable. But, the cost is said to increase proportionately with higher coating thickness. Hence, it becomes expensive.
  • Hot dip galvanization is provided with non-uniform coating, while the other one with uniform coating.
  • Hot dip galvanization is suitable for all sizes, while EGis suitable exclusively for smaller components.

Features:

Key features of electro galvanized steel include:

  • Corrosion Resistance: Provides effective protection against corrosion in indoor and mildly corrosive environments.
  • Aesthetic Appeal: Offers a shiny and visually appealing surface finish, suitable for applications requiring a decorative appearance.
  • Economical: Generally more cost-effective than other corrosion-resistant coatings such as hot-dip galvanizing or stainless steel.
  • Formability: Retains the formability of the base steel, allowing for a wide range of fabrication processes.
  • Environmentally Friendly: Electroplating process produces minimal waste and emissions compared to other coating methods.
  • Versatility: Suitable for a wide range of applications across various industries due to its corrosion resistance, aesthetic appeal, and formability.
  • Ease of Welding: Can be welded using standard welding techniques without significant issues.
