Thermo Mechanical Treatment or TMT bar is one of the most popular reinforcement bar used for construction projects. There are a number of TMT bars available in the market; however, out of all, TMT bars are manufactured using a special Tempcore technology which gives the TMT bar extra strength. Let’s take a look at the specifications of TMT bar manufactured by our cliente:
TMT bars are available in a number of grades and sizes and it conforms to IS: 1786:208 BIS standard. This standard is equivalent to a number of International Standards such as BST 500 of DIN 488 (Germany), ASTM A615 Grade 60 ( the USA), BS 444 Grade 460 (Britain).
Features of TMT Bars:
Better ductility and malleability
High yield strength and toughness
More bonding strength
Earthquake resistance
Corrosion resistance
High thermal resistance
Economical and safe in use
No loss in strength at welded joints
Ordinary electrodes used for welding the joints
