What Are TMT Bars and What Are the Different Types?
TMT bars, also known as Thermo-Mechanically Treated bars, are widely used in the construction industry for their superior strength and durability. These bars are manufactured using a special process that involves a combination of heat treatment and mechanical deformation. TMT bars have become the preferred choice for reinforcement in concrete structures due to their ability to withstand high temperatures, seismic forces, and corrosion. The process of manufacturing TMT bars begins with the selection of high-quality steel billets. These billets are then heated at a specific temperature and rapidly cooled using water jets. This rapid cooling process, known as quenching, forms a hardened outer layer on the bars, while the inner core remains relatively soft and ductile. This unique combination of strength and flexibility makes TMT bars ideal for withstanding bending, twisting, and other forms of stress during construction. There are different types of TMT bars available in the market, each ...
