To have control on every step of manufacturing, the group have installed the following modern facilities for producing of more than 3.0 lakh MT per annum of steel:
Our TMT steels bars are based on latest technology & design which guarantees the properties to produce as per international standards. German BST 420 S/500 S of DIM 488, British Gr. 460 of Bs 4449-1988 Egyptian Standard 262/1988 Gr. 36/52 and 40/60, Fe 415,500 & 550 of IS : 1786/'85,JIS.G.3112 1975 SD 30, 35,40,45 & 50 Swiss to par 550 S of SIA 162, French Fe E50 of NF A35-016. High strength reinforcement bar in grades of Fe-415, 500 and 550 as per IS: 1786/’85, that achieve their properties by on-line computerized controlled thermo processing.
We have received the prestigious "Ispat Udyog Ratan Award 2011" & "Dhatu Nayak Award 2012" for our quality & excellence. We are also awarded by UNDP, jointly with Ministry of Steel & as Energy efficient unit.
Higher strength and better elongation is a unique feature of OUR TMT bars. Designed to be much stronger than conventional bars, OUR TMT Bar build's a safer and stronger concrete structure with laser quantity of steel with a great savings over the market conventional requirement. OUR guarantees excellent Weldability, Ductility and Bendability. Tapered edge of OUR TMT bars provide better Weldability that help in making high strength connections with little overlap. Due to its low carbon content, these bars, can withstand better bending and re-bending without any reduction in strength.
For earthquake resistance, TMT bars structures need to have balanced stiffness, strength and ductility between its members, connections and supports. OUR TMT bars provide very high strengths with comparatively higher elongation values and better ductility, making them more earthquake resistance.
Test result for OUR TMT bars, have shown no loss of strength upto 500 degree C. At a temperature range of 550 degree C to 600 degree C, the yield strength decreases by 20N/Sq mm only. That is why, OUR TMT bars can be used easily in constructions prone to fire hazards.
Our TMT bars are more corrosion resistant than normal CTD bars. The fine layer of scale forms a protective layer, thereby preventing further corrosion. Whereas in CTD bars, this initial layer of scale falls down during twisting. Corrosion resistance can be further improved as per customer needs, by altering material chemistry.
