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.
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.
