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;
