1. What is TMT bar

Ans: TMT stands for Thermo Mechanically Treated. The TMT bars have a hard outer surface and a softer core. Their manufacturing process includes hot rolled steel wires passed through water. ... These bars have more yield strength than Mild Steel. Unlike TMT bars, HYSD bars are both hot or cold worked

  1. How are TMT bars superior to traditional steel bars?

Unlike traditional steel bars, TMT bars have several enhanced properties that make them better in every way. Some of the profound properties of TMT bars include better bending strength, better ductility, better malleability, better thermal resistance and better corrosion resistance

  1. What is the advantage of using Corrosion Resistance TMT bar.
  • Longer life
  • High yeld strength coupled with good ductility & bendability
  • No maintenance during fabrication
  • No extra precaution during welding
  1. What is the misconception about the raddish colour of TMT

Often due to interaction of rebar with moisture & air, the surface of the rebar develop raddish colour which being misunderstood with corrosion. In fact raddish rebar can be used

for construction without any hasitation so long they are in proper physical shape, weaight and strength.

  1. How to choose the right TMT bar as per Quality and Price?

There are countless TMT bar manufacturers in India and choosing the right one can get really confusing. In order to go for the right TMT Bars choose reputed brands such as MSP that have ISO certification and manufacture TMT bars under strict quality check.

Also, you need to be aware of the different grades that are available for TMT bars. These grades include Fe-450, 500, 500D and 550, 600 the higher the grades, the stronger the TMT bars. It is even important to self-check the bars before buying; check out for ISI and TMT™ identification marks on the TMT bars. Trusted companies such as MSP imprint these identification marks on every TMT bar.

  1. Are TMT bars earthquake proof?

Ductility is the most important feature of TMT bars when it comes to seismic resistance. Due to its unique manufacturing process, TMT bars are able to bring a higher level of flexibility to the structure. This ensures that when buildings are shaken up during an earthquake, it can retain its structure

  1. Why 500D is better than Fe 500 & Fe 415

Fe500D offers higher strength(measured as Yield Strength) & higher ductility(measured as %elongation)compared to Fe415 & Fe500 , due to lower impurities like sulphur & phosphorus, which allows you to use less reinforcement in a structure, saving cost.

Also, ductility is an important aspect of structure especially during extreme loading conditions like earthquake. Please refer to the above question for values on parameters.
