Extra High Strength Hot Rolled Thermo Mechanically 12 Mm Treated Bars

Product Description

These TMT Bars (Thermo-Mechanically Treated Bars) are Extra High Strength Reinforcing Bars that replace any form of cold twisting, a technology that was used in the past. After passing through the final Rolling Mill Stand, the steel TMT bars are given a quick, intense cooling as they pass through the specifically designed Tempcore Water Cooling System. The steel bar's surface layer is toughened as a result of the quick quenching. The temperature between the core (which is still hot) and the cooled surface layer is equalized, and the surface layer is tempered by the heat from the core, after this phase of intensive cooling by the Tempcore System is followed by further cooling in the atmosphere. The outcome is a tempered martensite zone on the periphery and a tempered martensite zone in the center.
