DRAWING STEELS
           

 

 

Applications

Hot dip galvanized sheets made of drawing grades are suitable for cold forming and deep-drawing. The sheets are used for the production of automobile parts appliences, in building industry and for production of profiles, corrugated sheets, roof coverings and engineering.

U. S. Steel Košice has implemented and maintains a quality control
system in accordance with the standard EN ISO 9001 and IATF 16949 for automotive industry, issued by TÜV SÜD.

 

Grades

Galvanized products are classified into quality grades according to their chemical composition and mechanical properties.
