Hot-dip galvanized steel made by voestalpine is characterized by high corrosion resistance, high-quality appearance, excellent working properties and a wide spectrum of applications. The portfolio of steel grades ranges from super deep-drawing grades to grades with highest strengths (advanced high-strength steels). Depending on customer requirements, voestalpine supplies a comprehensive range of available widths and thicknesses with tailor-made metallic coatings. A variety of surface finishing treatments also make it possible to extend the range of applications. voestalpine supplies high-strength steels with unique exposed-panel quality and offers a ZF coating for this purpose. The world's only hot-dip galvanized press-hardening steels made by voestalpine round off the extensive portfolio.
Some steel grades are available as galvanized hot-rolled strip:
Press-hardening steels for hot forming are available in various strengths and are coated with zinc or zinc-iron. Best crash behavior, high dimensional accuracy and very good joining properties are the hallmarks of components made of these materials.
Metallic coatings Z and ZM are available with normal (N) and small spangles (M). The surface of zinc-iron coating is spangle-free. Upon customer request, voestalpine supplies different zinc coatings per side (differential galvanizing).
This surface treatment provides excellent corrosion protection and processability, offering a high-performance alternative to conventional protective coatings for hot-dip galvanized steel strip. Corrender has been supplied in series since 2007, and voestalpine has established comprehensive product know-how and expertise in this area.

"At the Linz site, we manufacture a very extensive product mix in five different hot-dip galvanizing lines. We apply zinc coatings in various surface qualities on mild to high-strength steel grades. Our team of specialists meets the challenge with a high level of commitment and quality awareness every single day. We set the standards with additional chromium-free and environmentally friendly treatments such as clearcover® or multiface®.
