Steel grades

S390GD + Magnelis® structural steel grades

S390GD + Magnelis® structural steel grades are part of the Magnelis® product range.

Metallic coated structural steels are mainly used in:

  • construction: structural or non-structural profiles, composite flooring, roofing, and cladding
  • road and railway infrastructure: safety barriers, protection, and sound insulation wall panels
  • agriculture and farming: greenhouse structures
  • solar energy generation: structures for photovoltaic plants
  • tubular applications: structural tubes for scaffolding, road signs, and poles

Technical information

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.
