The history of the Indian subcontinent has many instances of earthquakes and tremors, despite not being close to the Ring of Fire. Its seismic history with high recurrence of earthquakes can be explained by the fact that the Indian plate crashes into Asia at an approximate pace of 47 mm per year. According to the geological views of India, as much as 54% of her land cannot sustain against earthquakes. Thus, it is essential to pick suitable TMT bars for any type of construction job. Find out about the different types of TMT bars that can be used.
Fe 500D
These are ideal for Zone 5 earthquake areas, and come with high elongation and flexibility along with moderately high strength. Such types of steel bars are regarded as the best TMT bars as these come with an appropriate combination of flexibility and strength. These re-bars are perfect for being used in bridges, dams, flyovers and other RCC structures with heavy loads. These are also ideal for other critical structures that need high design load or yield load without sacrificing the ductility aspect. The bars are known for being useful in diverse purposes, and are used popularly in coastal regions owing to their anti-corrosion resistant ability.
Fe 550D
The bars have low elongation and flexibility, and superior strength. These share similar properties as Fe – 500D, although these tend to vary in tensile strength and yield. The bars are used also in RCC constructions that get exposed to underground, marine or coastal environment. These are slightly better when compared to Fe 550, andare used when the construction project scale is a little heavier to bear for Fe 500D re-bars.
Fe 600D
These have extremely low elongation and flexibility, and even superior strength. The bars offer higher yield and toughness, as well as superior tensile strength as compared to other grades of TMT Steel. Thus is utilized for bigger RCC constructions. Fe is the symbol for “Iron”. Fe 600D re-bars happen to be a special grade of TMT Re-bars made under particular process conditions that offer superior strength than TMT Re-bars of Fe 500D grade.
The superior the grade, the more appropriate TMT bars are for structures that need industrial grade strength. When the grade is higher, the bendability is comparatively less. Thus, it is essential to use them in those structures where flexibility is not very important. Fe 500D and Fe 550D can be useful for constructing underground structures and multiple structures, while Fe 600 is ideal for use in industrial areas.
