Magnesium zinc is a cold rolled carbon steel that is continuously coated on both sides in a hot-dip procedure.
Adding aluminium and magnesium to the zinc bath produces a metal coating that greatly increases the cathodic protection of the zinc layer.
Main applications
Magnesium zinc is distinguished by very high resistance to corrosion and excellent processability.
Owing to a wide range of base steels, from forming and pressing to structural use, it can be used in all domestic and industrial applications.
Advantages
Reduction in thickness of zinc layer
Lower costs than with post-production galvanisation
Lower environmental impact
Excellent resistance to corrosion, up to 3 times greater than galvanized steel
Self-scarring ensures excellent protection on cut edges
Weight reduction
Special treatments
