STRUCTURAL STEELS
           

 

 

Applications

Structural grade sheets are used wherever strength parameters are prescribed, for supporting parts of building elements, bend profiles, etc.
U. S. Steel Košice has implemented and maintains a quality control system in accordance with the standard EN ISO 9001 and ISO/TS 16949 for the automotive industry, issued by TÜV SÜD.

 

Grades

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