THE NEW GENERATION
OF GALVANISED STEEL

5% Al-Zn ALLOY COATED STEEL

Zinc based coatings are widely used for corrosion protection of flat steel products. However, there are some significant problems on regular Zinc coating such as microcracking issue after severe forming, red rust at cut edge and less durable against acid and alkaline environments.

Galmaxx Alpha provides an excellent performance under those conditions and can be used in most applications where the other Zinc coating types cannot be used as the durability against corrosion resistance and formability is excellent.

What is Galmaxx Alpha?

Galmaxx Alpha is a new generation of hot dip galvanized steel coil that contains 95% Zinc, 5% Aluminum and trace amount of Magnesium. Galmaxx Alpha forms a eutectic microstructure in which both the high Zinc phase and high Aluminum phase freeze at the same temperature. This unique combination (Zinc and Aluminum) offers better sacrificial protection than alloys with lower zinc composition and better passive barrier protection than regular galvanized steel. The intermetallic alloy layer that forms between the Galmaxx Alpha's coating and the steel substrate is very thin, thinner than a similar layer that forms on regular galvanized steel, and is the reason for the extremely good formability of Galmaxx Alpha.
