Can you say – which is the backbone of any concrete structure? Is it the concrete or the bricks? No… It is TMT steel bars. Just as spinal cord supports our body and bears our whole weight, similarly TMT bars reinforce concrete structures and stand the load of beams, columns, slabs, building and also the weight of human beings and other belongings.

These bars are the strength of all structures and can withstand natural calamities like earthquake and windstorms. Beware of inexpensive steel bars because they contain low-grade materials and unknown elements that can damage a construction. This implies that these steel bars are not equipped with the right physical and chemical properties.

TMT steel bars are produced using unique metallurgical method called ‘Thermo Mechanical Treatment’. Bureau of Indian Standards approve these bars for using them in construction and building purpose.

However, customers now have become quite aware of these. Thanks to high-level education! They only demand for top quality product and are ready to shell out some extra penny for it.

Two Top Quality Steel Bars that is Thermo Mechanically Treated

There are various grades of TMT steel bars amongst which Fe 500 and Fe 500D are of top quality. Lets us now find out certain properties of these two grades of TMT steel bars.

In both these varieties, ‘Fe’ is the symbolic representation of ‘iron’, ‘500’ denotes minimum yielding power in N/mm2 and ‘D’ denotes high ductility property. They have low percentage of phosphorus and sulphur which can harm steel used for construction purpose. They also have low percentage of carbon to ensure weldability and ductility of the steel.

Subtle Difference between Fe 500 and Fe 500D

Fe 500 and Fe 500D TMT steel bars are suited for diverse kinds of construction projects. But, the latter variety of TMT bar has greater ductility than the former one. Both these bars have same tensile strength. The difference lies in their ductile feature.

Having high ductility enables Fe 500D bars to absorb sudden weights and this, in turn, make them the right choice for withstanding natural disasters like cyclones, tsunamis and tremors.
