TMT vs TMX: An Edge Over The Other
Steel is the most commonly used material in commercial and industrial building construction. The construction industry uses the maximum quantity of steel. It accounts for more than 50% of the world’s steel usage. However, two kinds of steel bars are mostly used for construction purposes: TMT steel bars and TMX steel bars. Whether it’s a TMT bar manufacturer in Kolkata or a TMX brand from any part of the world, their goal remains the same: to offer top value to their customers. Now, how do these two products differ from each other?
TMT or Thermo Mechanically Treated Bar also called Reinforcing Bar or Rebar in civil engineering, is a high-strength reinforcement bar. It has a rigid outer core and a soft inner core. These bars are also used in concrete reinforcement structures such as bridges, flyovers, dams, thermal and hydel power plants, industrial structures, high-rise buildings, underground platforms in metro railways, and rapid transport systems.
Thermex-powered steel or TMX is an advanced superior quality TMT steel bar. It has numerous properties, i.e., strength, weldability, flexibility, and not to forget its high tensile factor. TMT bars are usually used for civil construction purposes, whereas TMX bars are used for building commercial and high-raised structures.
The builders have always preferred TMT bars over TMX bars. So let us look at some of theri differences:
TMX and TMT bar price in Kolkata
Compared to TMX, TMT is cheaper in Kolkata. It’s also cost-effective.
A comparative study of the TMT and TMX bar features
The enhanced elongation of TMX bars transforms into greater flexibility, giving the resultant structure improved resistance during earthquakes and other natural calamities, making them the best resistance to seismic loads.
TMT bars have a ferrite-pearlite core and a rigid outer core. With the softcore, there is a minor sitting during a quake. But the robust exterior might return the building to its original position.
Thermex Technology vs Thermomechanical technology
The Thermex technology uses the predetermined quantity of high water pressure, which converts the bar surface to the hardened structure. On further cooling of the bar, a thermal exchange occurs between the inner and cooled outside martensite. The resultant bar structure on the surface is distinct tempered martensite at the periphery and a fine-grained ferrite-pearlite structure in the central zone.
On the other hand, Thermo Mechanical process involves heating and cooling. This process helps develop better properties in steel by refining its microstructure. It’s known as hot rolling, a process applied to handle vast quantities of steel.
Compared to Cold Twisted Deformed Bars (CTD), TMX bars are more corrosion resistant. The cold working in the former produces surface stresses resulting in higher corrosion rates. Also, during the cold twisting, the protective layer of CTD bars fall off. The Thermex processes work differently: there’s no cold working involved; the protective layer stays together.
To sum up, TMX steel is a high-quality TMT steel bar. It has many advantages over a TMT steel Bar. The former’s high strength, ductility, weldability and tensile factor make it unique and preferable. However, both of them are used in different places. Therefore, contact the best TMT bar manufacturers in Kolkata and buy TMT and TMX bars at a suitable price.
