What is Thermo Mechanical Treatment?
Thermo-Mechanical Treatment (TMT), is a metallurgical process that integrates work hardening and heat-treatment into a single process.
What is the need for TMT bars in construction?
Since TMT bars undergo thermo-mechanical treatment, they are extremely ductile and have high tensile strength. This makes it usable for every shape. It also provides great resistance to fire, earthquake, and corrosion. It is also easy to transport because of its lightweight build.
What are the various grades of TMT bars?
TMT bars are divided into various grades – Fe415, Fe500, Fe500D, Fe550 and Fe600. The number denotes the yield strength of the TMT bars and the letter ‘D’ denotes the ductility. Each grade has different properties and applications and therefore it is important to choose the right grade by knowing its application and usage.
Why should the TMT bars contain the least amount of Sulphur and Phosphorus?
TMT bar which contains a higher amount of Sulphur makes it prone to fire and a high amount of phosphorus causes fatigue to the bars.
What is the misconception about the reddish colour of TMT Rebar?
Often due to the interaction of the rebar with moisture and air, the surface of the rebar develops a reddish colour which is being misunderstood as corrosion. Reddish rebar can be used for construction without any hesitation as long as they are in proper physical shape, weight and strength.
