Manufacturing Process
TopTech TMT Bars are manufactured from superior quality billets , in adherence with the international quality standards and norms to ensure quality consistency . All billets are casted from first class ore sourced from high grade ore with exceptional chemical composition . The billets go through a test process to maintain the certified composition of Carbon , Sulphur and Phosphorus in the Rebar sections which makes them the best choice for construction . These are essential for being in compliance with tolerance parameters and high dimensional accuracy .
TMT Bar Features
Sturdy Build TopTech TMT Bars exhibit consistent superior strength and high ductility which ensures superior structures . Corrosion Resistant The controlled thermo mechanical treatment results in an uniform and thick tempered martensitic rim , completely free from internal stress .
This martensitic rim improves the corrosion resistance as well as fatigue strength . Seismic Resistance They support Seismic design due to its unique combination of strength , ductility and stress ratio .
Mechanical Properties
The advanced manufacturing process of TopTech TMT Bars makes it well surpass the minimum limit of strength and ductility specified in the standard IS : 1786 . The yield strength also far exceeds the standard norms and specifications . The UTS / YS ratio and percentage elongation that determine the seismic property of a rebar , is also very high in TopTech TMT Bars . This significantly enhances its ability to handle the pressure of earthquakes .

Top Gradation of TMT Bars
We all strive for the best quality materials while building our homes , but little do we know about how to choose the good quality materials . The quality determinant factor for the elementary building materials like the steel TMT bar precisely depends upon its quality gradation . Such quality gradations are primarily divided in three categories : Fe 415 , Fe 500 and Fe 500D .
Design load = Characteristic load x practical safety factor for load
