corrender—zinc-magnesium-aluminum coatings by voestalpine

Hot-dip galvanized steel strip: A new perspective


corrender is manufactured in continuous hot-dip coating lines. The use of magnesium and aluminum alloys in the zinc bath (composition of 1.5 weight % Mg and 2.5 weight % Al, each with a deviation of +/– 0.25 weight %) produces a high-performance protective coating characterized by its high degree of corrosion resistance and excellent working properties.

Product properties

The corrosion protection of corrender is significantly higher than that of conventionally galvanized steel strip. Because of the substantially improved protective properties of corrender, the metallic coating layer (zinc) thickness can be significantly reduced while maintaining the same level of corrosion protection.

corrender opens new potential for higher efficiency and thus reduces production costs. The low level of zinc abrasion, excellent deep-drawing properties and very good formability results in special processing properties that lead to considerable increases in production and processing efficiency.


corrender is supplied in widths up to 1,600 mm and thicknesses ranging from 0.5 to 2 mm (depending on product specifications such as steel grade).
