Thermo mechanically treated (TMT) steel, can be described as new-generation-high-strength steel having superior properties such as weldability, strength, ductility, and tensility, which meet the highest international quality standards. One of the most common types of TMT construction is used for home and building construction. We are manufacturers of TMT bars / TOR bars in Bangalore. The production of quality TMT bar depends on three major factors – quality raw materials, a properly designed and automated mill, and a well-designed quenching and tempering technology. All bars must be purchased based on the properties of yield strength, tensile strength, and elongation values.
