TMT bars are the cornerstone of any civil construction. They carry the load of the house, slabs, beams, columns, and, of course, the live load of people and their belongings. TMT bars must be able to withstand loads such as windstorms and earthquakes. Poor-quality materials, such as low-cost steel bars, are considered to contain high levels of unknown elements that are hazardous to the building.
TMT steel bars are steel bars that have undergone a special metallurgical procedure called "Thermo Mechanical Treatment." The Bureau of Indian Standards has certified these TMT bars for use in building and construction projects. The TMT steel brands available are Kalliyathu and Vizag.
