Tips when Using Galvalume Steel Coil
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.
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.
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.
