Thermo Mechanically Treated (TMT) bars

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
