Electro Galvanized Steel (SECC)

Electro-galvanized steel refers to steel that has undergone the electroplating process to apply a thin layer of zinc onto its surface. This technique provides a protective coating that enhances the steel’s corrosion resistance and improves its overall durability. 

Advantages

Corrosion Protection

The zinc coating provides effective corrosion resistance, extending the lifespan of the steel.

Aesthetic Appeal

The smooth and shiny finish makes electro-galvanized steel appealing for applications where aesthetics matter.

Formability

The process does not significantly alter the dimensions of the steel, preserving its original form and shape.

Cost-Effectiveness

Electro-galvanized steel is often chosen for its cost-effective corrosion protection compared to other coating methods.

Application

Electro Galvanized Steel (SECC) is mainly used in construction, light industry, automobile, agriculture, animal husbandry, fishery and commercial industries.

  • The construction industry is mainly used to manufacture anti-corrosion industrial and civil building roof panels, roof grilles, etc.
  • The light industry uses it to make home appliance casings, civil chimneys, kitchen utensils, etc.
    The automotive industry is mainly used to manufacture corrosion-resistant parts for automobiles, etc.
  • Agriculture, animal husbandry and fishery are mainly used for grain storage and transportation, freezing and processing equipment for meat and aquatic products, etc.
  • Commercially, it is mainly used for material storage and transportation, packaging equipment, etc.

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.
