PRECISELY THE BEST

voestalpine setzt einen neuen Maßstab bei Dickentoleranzen für warmgewalztes Stahlband

Count on thickness precision within the narrowest tolerances in hot-rolled strip

Guaranteed narrowest thickness tolerances down to one sixth of the standard!

At voestalpine, we are setting a new standard in the thickness tolerance of hot-rolled steel strip. State-of-the-art manufacturing lines and innovative measuring and control equipment achieve hot-rolled strip of the highest quality and within the narrowest thickness tolerances, guaranteed.

Count on precise advantages

  • Guaranteed values across the entire width and length of the strip
  • Stable processes and efficiency during production
  • Reproducible components with economical production

High-class steel strength

Our standard, the BASIC class, guarantees 50% of the thickness tolerances listed in DIN EN 10051:2010 for steel grades of classes A through D. 

The ADVANCED class guarantees up to one fourth of the defined EN tolerances, depending on the nominal sheet thickness. The ULTIMATE class even guarantees up to one sixth. 

ULTIMATE class 

  • up to 1/6 of the standard tolerance
  • for nominal strip thickness ranging between 2.5 and 6.0 mm

ADVANCED class

  • up to 1/4 of the standard tolerance
  • for nominal strip thickness ranging between 2.0 and 20.0 mm

BASIC class

  • 50 % of the standard tolerance set forth in EN 10051 
  • for nominal strip thickness ranging between 2.0 and 20.0 mm

Hot-rolled strip thickness tolerances

voestalpine ultralights Thickness Toleranzes

The tolerance values indicated in thickness tolerance classes apply to all voestalpine hot-rolled steels, regardless of the strip width and steel strength class (mild steels are rated separately). The reference values for all voestalpine tolerances are those specified in DIN EN 10051:2010.
