The Fe 550D/550D TMT bars are mostly used in earthquake-prone regions because this type of bar is highly resistant to seismic activity. The word TMT stands for ‘Thermo-Mechanically Treated’. In Fe 550D the word ‘Fe’ is the chemical symbol for iron, ‘550’ indicates minimum yield stress and ‘D’ stands for ’Ductile’.

The 550D TMT bars have a higher amount of tensile strength and elongation. They are used where the construction has to carry heavy loads. They are used in building stadiums, dams, tunnels, railway bridges, flyovers, airports, skyscrapers, hospitals, ports, malls, concrete roads, and more.

The 550D TMT bars contain Sulphur, Carbon and Phosphorous which help preserve the steel and resist earthquake shocks. The manufacturing process creates TMT bars that have a strong outer layer which provides the required strength to the bars. The soft inner core allows the bars to bend to withstand the earthquake movements during an earthquake.

What is the difference between FE 550 and FE 550D TMT bars?
There is a demand for high-rise construction and infrastructure projects. The buildings should be able to withstand seismic activity, time, temperature changes, natural disasters and others. The Fe 550 and Fe 550D bars are being used in a variety of constructions.

The Fe 550 bars are preferred in high-rise commercial and residential projects due to their seismic resistance and ductility. As the bars are strong and ductile they provide stability to these structures. They have better load-bearing capabilities and are used in areas with sudden heavy loads and high seismic activity.

The Fe 550D TMT steel bars are preferred in critical infrastructures because of their properties. These bars are earthquake-resistant because of the inner soft pearlite core which allows them to withstand dynamic and seismic loads. The bars can show a high fatigue resistance during seismic activity.

The bars have an elongation of up to 50%  more than the original length without losing out on measurements. The bars can be easily welded and can be used in world joints without a reduction in strength at the joints. The bars are corrosion-resistant and have moisture-resistant properties. Therefore they are used in the construction of bridges, canals, dams, sewage and more.

The bars can be bent and moulded into different architectural designs and aesthetic shapes. The bars have good thermal stability and can withstand temperatures between 400° C and 600° C. The TMT bars provide safety to the structures and residents living in them.

The bars are available in different diameters of 8mm, 10mm, 12mm and more. The 25mm steel bar price is worth paying for as it offers good strength and safety.

Manufacturing process
The iron is first placed in an oxygen furnace and then passed through an Electric Arc Furnace for further refinement. The metal is then transferred to a continuous casting machine. The steel flows into the casting ladle and then into the water-cooled mould. Here the steel solidifies and steel billets come out of the continuous casting machine. The billets can be hot rolled to get the desired shape.
