S450GD-HyPer® + Magnelis® structural steel grades

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.

S450GD-HyPer® + Magnelis® structural steel grades are mainly used in:

  • Construction: structural or non-structural profiles, roofing profiles
  • Solar energy generation: structures for photovoltaic plants

Technical information

These grades have additional technical guarantees compared with the EN 10346:2015 standard and fulfil the ductility requirements of Eurocode 3, Part 1.1:

  • A minimum proportional elongation of 15% (corresponding to 13% A80 for thickness below 3 mm)
  • Ultimate strain higher than 15x yield strain
  • Ratio of min. tensile strength to min. yield strength is more than 1.1
Magnelis® - Steels with zinc-aluminium-magnesium coating

Technical information

Magnelis® is a flat carbon steel coated on both sides with a zinc-aluminium-magnesium alloy*

  • Excellent corrosion resistance - at least 3 times better than galvanised steel in external applications
  • Complete edge protection thanks to the self-healing properties of Magnelis® on cut edges
  • Outstanding resistance in harsh environments (maritime, chloride, and ammonia atmospheres)
  • More cost-effective than batch galvanised steels due to simple manufacturing
  • Reduced maintenance costs compared to post painting

The excellent corrosion resistance properties of Magnelis® have been accredited with a Preliminary Technical Evaluation of Material (ETPM) by CSTB (Centre Scientifique et Technique du Bâtiment) and certified by a number of other external bodies, among them SP (Science Partner) and DIBT (Deutsches Institut für Bautechnik).

* This alloy is composed of 93.5% zinc, 3.5% aluminium, and 3% magnesium.
