Made from high carbon alloy steel. Has the following properties :

  • High tensile strength and tenacity ;
  • Heading process can be applied without losing its mechanical properties ;
  • Preliminary threading is not required in the threading process ;
  • If applied with strict control, spot welding with caging wire can be performed without losing mechanical properties ;
  • High bondability with concrete can be obtained because of its groveed surface ;
  • Re-straightening process is not required before cutting to lenght;
