  Electrogalvanised steels   Last update: 2011-2-23

The surface quality of electrogalvanised steels makes them ideal for the manufacture of visible components. Typical applications include indoor building, electrical and electronic appliances, metal furniture etc.

 

Properties
   

ArcelorMittal’s electrogalvanised steel is a flat carbon steel product, coated by electrodeposition on one or both sides with a pure zinc layer.
This coating is characterised by its uniform and regular thickness.

 

Advantages
   

ArcelorMittal’s electrogalvanised steel offers good resistance to corrosion for indoor applications.
It has also excellent weldability, due to the uniformity and regularity of the zinc coating.


Electrogalvanised products are an excellent substrate for painting, both in terms of adhesion and appearance. This advantage is further enhanced by the use of post-coating surface treatments: phosphating and/or passivation, Easyfilm® thin organic coating (please see data sheet E80 for the specific properties of Easyfilm®).

 

Applications
   

Electrogalvanised products are particularly suitable for industrial and domestic appliances. Some of the most common applications include:

  • Domestic appliances: washing machines, dryers, dish washers, cookers, microwave ovens, refrigerators etc
  • Teletronics: computers, laptop and hi-fi casings, casings for TVs, video and CD players, decoders etc
  • Furniture: cupboards, desks, shelves, electrical cabinets etc
  • Miscellaneous: air conditioners, road signs, electric motors, toys, construction items etc 

 

Recommendations for use
   

Storage

ArcelorMittal’s electrogalvanised steel is supplied passivated and/or phosphated and/or oiled to temporarily limit the risk of white rust formation. During transport and storage, all necessary precautions must be taken to keep the material dry and to prevent the formation of condensation. Rust prevention can be further improved by the application of an Easyfilm® thin organic coating. 

 

Forming and joining

The forming and joining techniques mainly used for uncoated steel sheets are also suitable for steel sheet with electrogalvanised coatings, even in the case of extreme forming operations.
Forming performance is improved if electrogalvanised steel is coated with an Easyfilm® thin organic coating.  

 

Painting

Electrogalvanised steel can be painted after degreasing and surface treatment when supplied oiled.
When phosphated or coated with an Easyfilm® thin organic coating, electrogalvanised steel can be painted directly, without any prior surface treatment. However, the paint must be compatible with the Easyfilm® resin.

 

Weldability
   

In electrical resistance welding, the welding current must be suitably regulated and regularly adjusted. Electrode life can be extended by regularly stepping up the welding current and periodically dressing (machining) the electrodes.
