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

An excellent all-rounder

Materials for cold forming

Mild steels
Structural steels
Micro-alloyed steels
Bake-hardening steels
High-strength IF steels
Carbon-manganese steels
Martensitic 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.

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).

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

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.

Coating	Thickness/mm	Width max./mm	Coating
Z and GI	0.45 – 4.00	1730	Z70 - Z600
ZF and GA	0.45 – 2.30	1730	ZF70 - ZF140
ZM (corrender)	0.45 – 2.30	1730	ZM90 - ZM200

"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

Design for Z and ZM	Mean roughness value Ra [µm]
Standard	0.6 – 1.9
Roughness: especially smooth	0.5 max.
Roughness: smooth	0.9 max.
Special option: half matt	0.7 – 1.3
Special option: matt	1.3 – 1.9

Numerous functional surfaces

Functional surfaces additionally improve the existing product properties in comparison to the high-quality base material and provides solutions to special applications:

Anti-fingerprint (multiface®) for the household appliance and construction industries
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
Optimized tribology and excellent oil distribution (prelube2)

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.

voestalpine supplies high-quality products that are specifically tailored to the requirements of modern HVAC systems—from corrosion protection, aesthetic surfaces, weight reduction, high strength and heat resistance. Our solutions improve the efficiency, lifespan and sustainability of your systems for comfortable surroundings.

Our steel products are used both indoor and outdoor HVAC equipment. The diverse applications of our steel grades is illustrated by the example of a heat pump.

multicover is a sustainable sealant for hot-dip galvanized steel strip (Z).

Almost invisible and yet so effective

multicover® 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 multicover® can be painted or adhesive-bonded without any additional conditioning and can be processed immediately. The surface features very good adhesive properties.
