Hot-rolled steel strip

Hot-rolled steel strip

Tailored to the specific needs of the customer, the product portfolio ranges from mild steels to meet the highest forming requirements to ultra-high-strength steels for the most stringent applications.

Portfolio

To meet every customer requirement we supply hot-rolled steel strip in widths up to 1,750 mm and thicknesses up to 20 mm. Our products are available in both pickled and unpickled condition, as slit or wide strip in coils. Even slit steel strip or cut shapes are possible. Hot-rolled steels made by voestalpine are supplied in a wide range of grades and qualities. A variety of alloys and rolling programs provide our customers with just the right steel for their specific applications.

  • Mild steels
  • Structural steels
  • Micro-alloyed steels (alform® steels)
  • Case-hardening and heat-treatable steels
  • Multi-phase and martensitic steels
  • Pole and rim steels
  • Enameling steels
  • Steels for gas cylinders
  • Weather-resistant structural steels
  • Linepipe steels

Hot-rolled steel strip

Hot-dip galvanized steel strip

Hot-dip galvanized steel strip

Hot-dip galvanized steel strip is characterized by its high degree of corrosion resistance, excellent working properties and a wide spectrum of applications.

Portfolio

Tailored to your specific needs, our portfolio ranges from extremely mild to advanced high-strength steel (AHSS) grades and includes widths up to 1,730 mm and thicknesses ranging between 0.5 mm and 3.5 mm. All hot-dip galvanized products of voestalpine have one thing in common: The best processing characteristics and highest degree of corrosion protection. Special features include Galvannealed and ZincMagnesium hot-dip galvanized steel strip.

Steel grades

  • Mild steels for cold forming
  • Structural steels
  • Micro-alloyed steels
  • Bake-hardening steels
  • Higher-strength IF steels
  • Dual-phase steels
  • Complex-phase steels
  • TRIP steels
  • Press-hardening steels for hot forming (phs-ultraform)

Surfaces

  • Surface types ranging from standard A surface to high-end C surface properties
  • Adjustment of defined strip roughness possible
  • Post-treatment to protect against the formation of white rust: wide variety of oils, chromium-free passivation, anti-finger-print system or micro-phosphating

Different types of hot-dip galvanized steel strip 

  • Conventional hot-dip galvanized steel strip (Z) with zinc coating thicknesses ranging from Z70 to Z600 
  • Hot-dip galvanized steel strip galvannealed with zinc-iron coating (ZF) allows coating thicknesses ranging from ZF70 to ZF140. 
  • Hot-dip zinc-magnesium galvanized steel strip (ZM); ZM90–ZM200

Electrogalvanized steel strip

Electrogalvanized steel strip

Electrogalvanized steel strip for highest corrosion protection and best surface quality.

Portfolio

The electrogalvanized steel strip portfolio ranges from extremely mild to advanced highest-strength steel grades. All of these grades are characterized by high-quality appearance and excellent shell quality. The mechanical properties are equal to those of cold-rolled sheet. Electrogalvanized steel strip is available with a galvanized coating on one or both sides. The zinc coating layer thicknesses range between 2.5 and 7.5 µm.
