What are TMT bars?

TMT or Thermo-Mechanically Treated bars that have a tough outer core and a soft inner core. TMT bars are known for their high yield strengths and are widely used in reinforcement concrete structures.

What are the available grades of A-One Gold TMT Bars?

A-One Gold TMT Bars are available in two different grades: Fe-500 and Fe-500 D.

What do the numbers in the different TMT Bar grades imply?

The numbers in the different grades of TMT Bars (Fe-415, Fe-500, etc.) imply the amount of stress that the bars can withstand before they start to deform. For instance, TMT Bar Fe-500 would deform at a pressure of 550 Newton/mm2.

How are A-One Gold TMT Bars manufactured?

A-One Gold TMT Bars are manufactured at A-One Steel Group’s state-of-the-art steel plant using thermo-mechanical treatment process. It involves hot rolling of MS Billets followed by instantaneous quenching and cooling. This immediate temperature switchover hardens the outer surface while keeping the core hot and soft. The rods are then subjected to atmospheric cooling, which renders the surface strong while making the inner core ductile. Thus, TMT bars manage to strike a balance between strength and ductility making them highly useful in all sorts of construction projects.

Are A-One Gold TMT Bars corrosion resistant?

Reinforced A-One Gold TMT bars exhibit good corrosion resistance over traditional carbon steel reinforcing bars.

What are Billets?

Billets are a semi-finished product that is extensively used in rolling mills to produce bars, wire rods, and structural steel. They are also used in machine and forge shops where engineering goods are produced.

In which areas are structural steel mainly used?

Structural steel, commonly called Section Steel, is mainly used in fabrication and construction of various heavy and light structures like bridges, towers, industrial sheds, warehouses, gates, doors, grills, windows, etc.

What are the different shapes in which structural steel come?

Structural steel is available in a wide range of shapes viz. Beams, angles, channels, flats, squares, etc.
