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 manufacture
  • Reduced maintenance cost 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,

** C5: the most severe environment
