Rail


As a lifeline for mass transportation, railways have to continually innovate and steel play a pivotal role in providing choice for heavy haul applications by meeting the demanding conditions of the mass transit and freight networks in becoming faster and further. Head hardened rail offers greater efficiencies through its ability to handle higher axle loads with low deformation and wear. These rails are also used in tracks where higher acceleration and deceleration are inevitable. Here at STC we keep up with the pace of the world and deliver what’s best it has to offer
