Properties

Galfan is a flat carbon steel product coated on both sides with a zinc-aluminium alloy. The coating is composed of 95% zinc and 5% aluminium and is applied by means of a continuous hot dip galvanising process.
Galfan is available in a very wide range of steel grades: steels for cold forming and deep drawing applications, structural steels and High Strength Low Alloy steels.

Advantages

Because of the nature and the particular structure of its coating, galfan is characterised by very good ductility and excellent forming performance. It is therefore recommended for parts requiring severe deep drawing.

 

The presence of aluminium in the coating makes the corrosion resistance of galfan significantly higher than that of standard hot dip galvanised steel of equivalent thickness. Galfan offers excellent edge corrosion resistance.

Applications

Galfan is used in numerous industrial applications, such as:

Recommendations for use

Storage

Galfan is supplied passivated and/or oiled to temporarily limit any 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. Improved rust prevention can be obtained by the application of Easyfilm® (please see data sheet E80 for the specific properties of Easyfilm®).

 

Forming and joining

The forming and joining techniques currently used for uncoated steel sheets are also suitable for galvanised steel.
The coating thickness must therefore be compatible with both the desired degree of corrosion protection and the requirements of the forming and welding processes envisaged.
Forming performance will be improved if galfan is coated with an Easyfilm® thin organic coating.  

 

Painting

The organic paintability of galfan is very good both before forming (coil coating) and after forming (post-coating).
Degreasing and a suitable surface treatment are necessary before painting when the material is supplied oiled. Galfan supplied with an Easyfilm® thin organic coating can be painted directly without any surface treatment. However, the paint used 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.
