Ctd bars
WebThe use of progressively higher strength reinforcement steel resulted in increased demand for smaller diameter steel bars, to replace higher diameter steel bars, due to economic reasons .Production of CTD bars or TMT bars was limited to 8mm dia. The solution was found by invention of a new type of reinforcement bar ,the high strength deformed bar. WebCTD bars have a yield stress that is 50% higher than conventional mild steel bars. These rebars come in diameters ranging from 4mm to 50mm. This type of rebar generates higher operating stresses while utilizing less steel. Due to cold twisting, there is surface stress and visible fissures, which results in decreased ductility, increased ...
