CHARACTERISTICS
I. Cold rolled products made of low carbon non-alloyed structural steel are used for the production of flat or cold-formed structural elements. Their application is determined by the minimum value of the yield point, or by the tensile strength.
II. Cold rolled products made of fine-grained, atmospheric corrosion
resistant structural steel are mostly used in the building industry and for various constructions. Improved resistance is due to the surface layer of oxides of alloying elements.
Coils
wide strips with a rolled width of 600mm and more, supplied in coils
Strips
cut from wide strips, width less than 600mm, supplied in coils
Sheets
sheets cut from wide strips supplied in sheets
