Hot-dip galvanized steel strip

An excellent all-rounder

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 (ahss 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.

Materials for cold forming

  • Mild steels
  • Structural steels
  • Micro-alloyed steels
  • Bake-hardening steels
  • High-strength IF steels
  • Carbon-manganese steels
  • Dual-phase steels
  • Dual-phase high-ductility steels
  • Complex-phase steels
  • Complex-phase high-ductility steels

Some steel grades are available as galvanized hot-rolled strip:

  • Hot-rolled low-alloyed or microalloyed steels
  • Hot-rolled ferritic-bainitic steels
  • Hot-rolled complex-phase steels

Materials 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.

  • phs-ultraform®
  • phs-directform®
  • phs-rollform®
  • phs-multiform

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)

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).

"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®.

Surface quality

  • As-coated surface (A)
  • Improved surface (unexposed and B)
  • Best surface (exposed or C) for special requirements such as exposed panels (IF steels) in the automotive industry for additional benefits:
  • Minimum waviness
  • High contour sharpness in reflections
  • Also for ZM corrender coatings)
  • Optimum forming properties
  • Efficient painting

Numerous additional treatments

Subsequent surface treatment additionally improves the existing product properties in comparison to the high-quality base material and provides solutions to special applications:

  • Chemical passivation and/or corrosion protection oils protect against white rust formation and are free of chromium. (clearcover®)
  • Forming aids such as a phosphating or passivation layer (dryform)
  • Direct coating capacity for enameling steels (direct-e®)
  • Anti-fingerprint (multiface®) for the household appliance and construction industries

Further processing

Hot-dip galvanized steel strips available in a wide range of widths and lengths:

  • Wide strip
  • Slit strip (slit)
  • Cut-to-length sheets
  • Blanks

Supply pursuant to EN 10346 and VDA 239100 Deviations upon agreement.

A wooden fire door?

Yes! Available in a very large number of different colors, colofer® is available in many different designs that appear deceptively genuine, including stainless steel, wood or carbon. A special 3D feel makes our wood surfaces hard to differentiate from authentic wood surfaces. A broad portfolio of additional steel products and efficiency-enhancing treatments is also available.

The use of colofer® instead of powder-coated components saves costs!

colofer® is the brand name for pre-coated steel strip made by voestalpine. You can significantly reduce your costs and increase efficiency by switching from powder-coated components to colofer® CASING. colofer® CASING is characterized by particularly high scratch resistance and can be processed as a precoated product without the use of any protective film. With the help of the colofer® color service, the desired color shade can be easily reproduced and, thanks to the Steel Service Center, the product can be supplied in coils, cut sheets or slit strip.

Precoated steel strip for lighting

colofer®, the precoated steel strip made by voestalpine, can be formed easily and, depending on customer requirements, can be coated on one side (top side only) or on both sides (top and bottom side) with a coating specially developed for the lighting industry. Up to 95 gloss units and an epsilon value of ≥ 85 can be achieved. With the help of the colofer® color service, the desired color shade can be easily reproduced and, thanks to the Steel Service Center, the product can be supplied in coils, cut sheets or slit strip.

Almost invisible and yet so effective

multiface® is a multifunctional, nearly invisible protective coating with excellent anti-fingerprint properties. The coating provides excellent corrosion protection during transport and storage and very good forming properties without having to employ any additional lubricants. Components coated with multiface® can be painted or adhesive-bonded without any additional conditioning and can be processed immediately. The surface features very good adhesive properties.

Are you familiar with corrender as a powerful alternative?

By adding magnesium (~1.5% by weight) and aluminum (~2.5% by weight) to the zinc strip, a high-performance protective layer is created which, with the same layer of the metallic protective layer, provides outstanding corrosion protection and excellent workability as compared to conventionally galvanized steel strip.

Heating Ventilating & Air Conditioning

The outstanding product properties of colofer®, corrender, direct-e® and multiface® offer the best possible conditions for efficient solutions in ventilation and air conditioning units. High resistance to weathering and corrosion, uncomplicated formability, simplified further processing and the choice of different colors and surface designs with nature-friendly manufacturing processes and proven voestalpine service offer ideal conditions for new impetus in the industry.
