TMT Bars

Thermo Mechanically Treated (TMT) rebar is one of the most iconic products in Shyam Metalics product portfolio. Our Thermex TMT Bars is one of the most preferred brands among the structural engineers and architects and is widely used to augment strength of cemented structures.

Although for ages people have believed that cement alone is elemental for the strength of the structure but the twisted length of the TMT bars that juts out from the buildings under construction are most instrumental in providing the real inner strength of the super structures that fascinates us and brings our eyes to an awe. If cement depicts the muscle of an architectural glory TMT bars are its spine and bones. Shyam completely understands the sensitivity of the segment where people invest their live’s savings and nations rely for their development and growth and therefore are obsessively attentive to surpass the value of their aspirations.

Keeping in mind the challenges that varies with geographies our TMT bars are designed and manufactured conforming to the highest standards for better performance along with a competitive economic advantage. The combined chemistry of steel and proper quenching system prevents TMT bars from rust and corrosion to even withstand the brackish ground water of the coastal regions and in areas where toxic gas emissions seriously impact the environment. They are also capable of resisting fire from 600° C - 650°C. The fine combination of Carbon and manganese exhibit a good cabon equivalent (CE) that may not be greater than 0.42%, that makes the TMT bars capable of more elongation and provides better bendability to offer more earth quake resistance. The FE 500D grade steel that is used affirms the presence of minimum sulphur and phosphorus ensures fewer harmful impurities one on hand and at the same time saves the usage of steel by 17% resulting a significant savings in the cost. The Shyam TMT Bars comes with a hollow lower and uniform sectional weight that ensures more resistant to seismic forces while contributing to another 3-4% savings in cost. Shyam TMT harmonizes strength and savings into a perfect equilibrium.

Shyam TMT Bars has thus been omnipresent in the new age airport, metro and railway stations, IT and industrial hubs, solar supports, conveyor galleries, sky scrapers and in almost every kind of structural excellence, working tirelessly to reciprocate the trust and respect it has earned from the people.
