Tips when Using Galvalume Steel Coil
1.Storage
Galvalume coil is supplied passivated or oiled to temporarily limit
any risk of black 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 protection can be
obtained by the application of an Easyfilm coating.
2.Forming and joining
The forming and joining techniques currently used for uncoated
steel sheets are also suitable for Aluzinc coil.
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 is
improved if Aluzinc is coated with an Easyfilm thin organic
coating.
3.Painting
Galvalume coil can be painted after degreasing and surface
treatment when delivered oiled. Aluzinc coated with an Easyfilm
thin organic coating can be painted directly, without any prior
surface treatment. However, the paint must be compatible with the
Easyfilm resin.
4.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 the electrodes.
