Magnelis® is a flat carbon steel product coated on both sides with a zinc-aluminium-magnesium alloy. This alloy, composed of 93.5% zinc, 3.5% aluminium and 3% magnesium, is applied by means of a continuous hot dip galvanising process. This optimum chemical composition has been selected to provide the best results in terms of corrosion resistance.

Magnelis® 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.

Thanks to its 3% magnesium content, Magnelis® offers self-healing on cut edges and superior corrosion resistance in chloride and ammonia atmospheres. This high corrosion resistance means that less metallic coating is required (weight reduction), which facilitates processing steps such as welding.

The zinc-rich metallic coating composition permits all the conventional processing operations possible with standard hot dip galvanised steel: bending, drawing, clinching, profiling, stamping, welding etc. The friction coefficient of Magnelis® coated steel is lower than that of standard hot dip galvanised steel, leading to reduced powdering during forming operations.

Technological properties

Application areas

Magnelis® can be used in numerous industrial applications, such as:

  • Solar energy generation: structures for photovoltaic and thermal solar plants
  • Construction: structural or non-structural profiles, roofing & cladding, decking, cable trays, expanded metal, gratings, composite flooring, concrete moulds
  • Road and railway infrastructure: safety barriers, protection equipment, sound insulation wall panels, walls providing protection against hail
  • Agriculture and farming: barns, greenhouse structures, agricultural equipment
  • Tubular applications: structural tubes for scaffolding, road signals, poles

  • Certifications

    Magnelis® is approved for use in Civil Construction by different national bodies:

  • Germany: DIBt Z-30.11-51 for Magnelis®
  • France: ETPM for Magnelis® by CSTB
  • Sweden: Technical Approval no. SC0559-13 for Magnelis®

  • Coating

    * The coating weights in this table have been calculated with the density of Magnelis®.

    The density of the Magnelis® coating is 6.2 g/cm3, due to its chemical composition.



    Magnelis® 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.

    Processing methods

    The forming techniques currently used for galvanised steel are also suitable for Magnelis®. Magnelis® behaves very well during profiling operations. The coating thickness must be compatible with both the desired degree of corrosion protection and the requirements of the forming processes envisaged. A minimum bending radius of 2x sheet thickness is recommended.


    In resistance spot 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. The coating thickness must be compatible with both the desired degree of corrosion protection and the requirements of the welding processes envisaged. Magnelis® can be arc welded, laser welded, brazed or high frequency induction welded, taking the same precautions as with galvanised steel. For use in outdoor applications a reprotection of the weld seams from arc welding and high frequency induction welding is recommended.
