clearcover® - the sustainable and environmentally friendly passivation coating for galvanized steel strip

clearcover® an environmentally friendly passivation system without chromium III or chromium VI and it is free from heavy metals such as molybdenum, manganese or cobalt. The additional innovative treatment is applied to hot-dip galvanized or electrogalvanized steel strip and can be supplied in combination with oil or phosphating.

clearcover® is an environmentally friendly passivation for galvanized steel strip and offers very good corrosion protection.

The use of clearcover® on passivated galvanized steel provides excellent properties such as reliable corrosion protection during storage and transport, direct coatability and more.

Multiple certifications

Extensive material certification is naturally a minimum requirement at voestalpine in our effort to provide high-performance additional treatments. Actual properties often go far beyond the standard minimum requirements.

voestalpine relies on internationally renowned certifications.

Steel strips

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.

Hot-dip galvanized steel strip

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
Hot-dip galvanized steel strip impresses with robust coatings and versatile applications. 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 housings 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.

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.

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 the standard surface (A) to the improved surface (B) to the highest-quality exposed component surface (C) for demanding applications. The exposed component surface features minimal waviness, high contour sharpness and is ideal for exposed panels in the automotive industry.

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.
