Nowadays, with the advancement of rolling technology and high automation in terms of temperature control and cooling speed and the existence of the Thermax system, it is possible to lower tread bars 520 and above with weldability and optimum mechanical properties with It produced good ductility.
Fortunately, the National Standards Organization of Iran, along with the internationally accredited standards in the new revision, adopted and implemented the ribbed bars 500 and 520. In this regard, Desert Steel Complex, which has been active in the production of high strength brick bars since its inception, has adopted the new standard for mass production of Tread 520 rebar.
