ArcelorMittal's hot dip galvanised steels consist of a steel substrate with a metallic zinccoating applied by means of a continuous hot dip galvanising process. Metallic zinc coatings are available in steel grades ranging from steel for bending and deep drawing applications, to structural steels and high yield strength steels.
A glossy surface finish obtained under specific skin-pass conditions (either non-skin-passed or skin-passed with smooth cylinders to obtain low roughness) can be provided if required at time of enquiry.
Advantages
Hot dip galvanised products offer excellent corrosion resistance combined with very good forming properties. The coating process can apply very thick zinc layers, up to 725 g/m² (total of both sides).
Applications
ArcelorMittal's hot dip galvanised steels can be used in a very wide range of applications for industrial markets, both indoors and outdoors. Some of the most common applications are:
Building: wide sections for roofing and cladding, doors, door frames, metallic ceilings, partitions, structural members etc
Domestic appliances: all appliances for this sector (both white and brown goods) are manufactured with hot dip galvanised steels
Miscellaneous: electrical cabinets, aeraulic components, air conditioners, road signs etc
Zinc hot dip galvanised steel is suitable for contact with foodstuffs under certain conditions, as specified in the Regulation (EC) No. 1935/2004 and French standard NF A 36-712-1. Please contact us for further information on this subject.
Recommendations for use
Storage
Galvanised strips are usually supplied passivated 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 protection can be achieved by the application of an Easyfilm® thin organic coating (please see data sheet E80 for the specific properties of Easyfilm®).
Forming and joining
The forming and joining techniques currently used for uncoated steel are also suitable for galvanised steel. It is essential to select a coating thickness that is compatible with the forming and joining processes envisaged, without compromising the desired degree of corrosion protection.
Painting
Hot dip galvanised steels can be painted after degreasing and surface treatment when supplied oiled. If an Easyfilm® thin organic coating has been applied, they 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.
