TMT Bars
SML produces a TMT bar under the name SML TITAN at the Loidapada Plant using an in-house hot Billet process. The low sulphur and phosphorus content of TMT bars meet the BIS-standard (TMT – FE 500D) which improves ductility and ability to withstand tremendous shock loads. Our product is used in a wide range of applications from Highways to High-rise buildings in urban and rural settings across India.
