Hot-dip galvanized steel strip

Hot-dip galvanized steel strip made by voestalpine is characterized by high corrosion resistance and offers solutions for hot and cold forming. The product portfolio is versatile and ranges from deep-drawing grades to grades with the highest strength that have properties tailored to each application, including best surface, optimum formability or low sensitivity to edge cracking. Hot-dip galvanized steel strip is available in all surface versions with various metallic coatings and a wide range of widths and thicknesses.

  • Reliable corrosion protection thanks to high-quality metallic coatings such as zinc, zinc-iron and zinc-magnesium that are ideal for durable components under demanding conditions.
  • A broad quality portfolio from soft deep-drawn grades to high-strength dual-phase, complex-phase and martensitic steels—all tailored to a wide range of applications.
  • Versatile for hot and cold forming from complex deep-drawn parts to press-hardened structural components.
  • corrender® - an efficient alternative: Significantly improved corrosion protection when compared to classic galvanized steel strip with a thinner layer. The coated surface impresses with excellent formability, low friction and high processing efficiency.

From lightweight design to corrosion protection solutions for the highest demands 
The numerous applications of hot-dip galvanized steel strip are highly convincing. Typical applications are found in the automotive industry, for example in crash-relevant structural parts, A and B pillars, seat structures, sills and exposed components. The material is also widely used in the construction and household appliance industry, for example in roof and facade elements, doors, ventilation ducts, household appliance and control cabinets. Other areas of application include the production of tubes, structural members and modular shelving systems in which high dimensional stability and long-term corrosion protection are required. Depending on the requirements, various coatings are available, including corrender® zinc-magnesium as well as a wide range of different strengths.

Steels for cold forming

Hot-dip galvanized cold-forming steels made by voestalpine are perfectly suited for modern production processes. Whether deep drawing, bending or roll forming, the excellent formability, stable edge performance and outstanding surface quality ensure maximum process reliability. Thanks to a variety of steel grades and coating options, they offer optimum solutions for demanding components. Hot-dip galvanized strip extends the available thickness spectrum upward.

Steels for hot forming

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

  • Zinc (Z) for applications subject to average corrosion (galvanized)
  • Zinc-iron (ZF) for corrosion protection with highest weldability requirements (galvannealed)
  • Zinc-magnesium (ZM) for best cathodic corrosion protection (corrender®)

corrender® is the high-performance zinc-magnesium-aluminum coating made by voestalpine.

The corrender® surface achieves a significantly higher corrosion resistance than conventional galvanized steel strip, despite its reduced layer thickness. The surface is characterized by excellent forming properties, minimized friction and efficient postprocessing.

Surface quality

Hot-dip galvanized steel strip is available in a variety of surface finishes from standard to improved surfaces. For example in the automotive industry, the best exposed components with minimum waviness and high contour sharpness provide an ideal solution for particularly demanding applications.

Functional surfaces

voestalpine offers more than high-quality steel strip. Functional surfaces provide additional protection, facilitate production processes and increase efficiency. They contribute to quality assurance, cost savings and conservation of resources. A wide range of solutions enables optimum adaptation to specific requirements.
