Iron rod and TMT bars
In olden days, houses across India were built with iron rods and concrete slabs. The rods would begin to rust soon at early stage. It affects the stability of the structure in the extensive run. This leads to a frequent repair of the house.
The structures made using the inexpensive and inappropriate raw material will not last for a long. The common cause of the structural disaster is due to poor quality of material and poor planning. For this, we use the TMT steel that holds the concrete bars together.
TMT bars
TMT – Thermo Mechanically Treated
TMT Bars have a tough outer surface and a soft inner core. These bars are corrosion resistance and used for constructing the bridges, residential buildings and industries. They are superior to conventional TOR steel bars.
TMT bars – Grades in India
The TMT bar grades are Fe415, Fe500, Fe550 and Fe600. The larger grade TMT bars must be used on the floors and roofs of the building. The lesser grade bars are used in the building balcony fences and other attractive structures. There are many Steel Suppliers and Steel Dealers in Chennai. Most of the people approach them to buy the best bars for their construction. They are able to choose the bars based on their requirements and budget. All variety of steels and bars are available with the steel suppliers.
Primary steel producers
The primary steel manufacturers convert iron ore into the steel. From iron ore mines to steel manufacture is done at their sites. They produce the basic steel of standard specification.
Secondary steel producers
Secondary steel manufacturers are considered as mini steel plants. They make the steel by melting the sponge iron and melting scraps. The secondary steel is good for many types of uses.
Difference between primary and secondary steel
Most of the contractors prefer Fe500D due to its strength and ductility. They can bend to a maximum extent before breaking. TMT bars have high strength and corrosion resistance. This will help the engineers to create structures they could not have imagined.
