Steel grades
S420GD-HyPer® + Magnelis® structural steel grades
S420GD-HyPer® + Magnelis® structural steel grades are part of the Magnelis® product range.
They are mainly used in:
- construction: structural or non-structural profiles, roofing profiles
- solar energy generation: structures for photovoltaic plants
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.
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
