Radha TMT bars deliver exactly what builders, architects and consultants want – the strength, durability and resistance of steel. The superior quality of Radha TMT bars, manufactured using THERMEX (also known as ‘Quenched and Tempered rebars’), is a result of four key factors:
AUTOMATED BAR MILL
TESTING AND QUALITY
We ensure that Radha TMT bars not only meet the highest quality specifications but are suited to the tropical conditions of the region.

Radha TMT Bars are technically advanced, thermo-mechanically treated and are different from most other bars because of the state-of–the art THERMEX Quenching & Self Tempering (QST) Technology, invented by Sir Franz Tamm of Hennigsdorfer Stahl Engineering GmbH.
Thermo Mechanical Treatment (TMT) or processing, is a metallurgical process that integrates work hardening and heat treatment with one single process. The Thermex – quenching process produces bars from low carbon steel which are of very high strength. The process quenches the surface layer of the bar, which pressurizes and deforms the crystal structure of the intermediate layers, and simultaneously begins to temper the quenched layers using the heat from the bar’s core.
TMT steel bars are of very high strength and complement “Reinforced Cement Concrete” (RCC) which has become an integral part of every structure. TMT together with RCC can be molded into any desired shape with which the Steel Bars are able to withstand any load put upon them. TMT Bars should conform to the best in class quality standards, so that the risk of unforeseen forces that may develop because of any live or dead load acting upon the structures, that may cause loss of life and property can be avoided. Only TMT bars should be used to secure the structural creations of mankind and to make them sturdy and long lasting for generations to come.
To make any structure strong and durable only TMT bars should be used. They can be used for all types of construction works ranging from single storied houses, multi-storied buildings/complexes, tunnels, bridges, flyovers, dams and even TV towers. Developed countries use only TMT bars for every type of construction – small or big.
The commonly manufactured and used grades are Fe – 415, Fe – 500, Fe – 550 and their D types also. RADHA 550 TMT BARS have the highest tensile and load bearing strength amongst all the grades.
Radha TMT manufactures high strength TMT Bars in Fe 500 & Fe 550 grades conforming to IS 1786:2008 standards.
The sizes available are 8mm, 10mm, 12mm, 16mm, 20mm, 25mm, 32mm. All the bars manufactured by RADHA TMT use the Thermex process.
- German Thermex technology, most advanced technology.
- Hot/ cold billet charging facility.
- Billet weighing facility.
- High pressure water de-scaling facility-Ensures scale free TMT bars.
- High speed continuous mill for less exposure to atmosphere which helps in maintaining close dimensional tolerance and uniform weight across the length of the bar
- Inter stand tension control rolling MTC (Minimum Tension Control).
- Online rapid water quenching unit for production of thermo-mechanically treated high strength Bars (TMT bars).
- Sparkonix computer controlled notch making CNC machines for even spaced and precise depth rib cutting.
Radha 550 TMT Bars posses precise and uniform parallel rib pattern engraved through computer controlled notch making Sparkonix CNC machines which results in excellent bond strength with concrete.
Consistency of parallel rib pattern is uniform and guaranteed in each and every bar as the roll pass in finishing mill stand is not over used, thus ensuring the final product delivered to the is of extremely high quality.
Radha 550 TMT Steel Bars have Precise and uniform parallel rib design which results in superior mechanical properties as compared to the other ordinary Steel Bars in the market. Parallel Ribs on Radha 550 TMT Bars are produced with the help of Sparkonix CNC machine in state of the art high speed automated rolling mill machines which give very Close dimensional tolerance, superior surface finish, uniform & precise parallel rib pattern to the Steel Bars.
The following points give Radha 550 TMT Bars an advantage over their competitors:
Weight and length: Radha 550 TMT Bars follows strict BIS norms and are manufactured as per BIS standards promising superior strength, ductility and bendability compared to other tmt manufacturers in the same sectional properties.
Bond Strength: Radha 550 TMT Bars provides superior strength to the buildings as they posses uniform and precise parallel rib pattern, which ensures excellent bonding with concrete, resulting in stronger and more durable structure.
Dimensions: with the help of high speed rolling mill Radha 550 TMT Bars have close dimensional tolerance, superior surface finish, standard weights and precise rib pattern.
Bendability: Radha 550 TMT Bars have high elongation which means that the TMT bars are capable of absorbing large amount of energy by plastic deformation before undergoing failure by fracture. Due to its good expansion capacity it holds the columns against failure during the earthquake. – a boon for ductile constructions in the seismic zones.
Weld-ability: Radha 550 TMT Bars have low carbon equivalent and is directly related to hydrogen induced cold cracking which is the most common weld defect for steel. Higher concentration of carbon and other alloying element tend to increase hardness and decrease the weld-ability.
Corrosion Resistant: Radha 550 TMT Bars have minimum or negligible residual stresses in order to prevent any chance of rusting, and also by micro-alloying, coupled with the state-of-the-art rolling technology, which imparts excellent corrosion resisting properties in the TMT bars.
Earthquake Resistance: Radha 550 TMT Bars have high UTS/YS ratio which signifies that steel is capable of elongating to a large extent when loaded beyond yield point and It is with this view that some of the international specifications stipulate fairly high values for the UTS / YS ratio.
Resistant to fatigue : Radha 550 TMT bars can withstand any dynamic loading due to their excellent strength of the surface layer. This makes Radha 550 TMT Bars a unique choice for super strong construction.
Cost Savings: Radha 550 TMT Bars have high UTS/YS ratio and high elongation which results in lesser consumption when compared to the other TMT of the same sectional properties which has low UTS/YS ratio and lesser elongation. As per studies 550 Grade TMT with high strength saves about 10-14% than the corresponding lesser strength TMT of Fe500
Keeping all the above points in mind, Radha Smelters launched their Earthquake resistant, high quality, MAHA SHAKTISHALI Radha 550 TMT Bars which ensures high quality.
The Steel consumption depends on the strength of the TMT Bar. Higher the strength, lower will be the consumption.
Radha 550 TMT Bars are manufactured in a world class state-of-the-art high speed rolling mill ensuring excellent yield strength which exceeds the parameters specified in the BIS standard IS-1786 resulting in material saving of approx 24% compared to the Fe 415 TMT manufactured by the secondary producers. Not only this when the quantity of steel consumption reduces you save on transportation cost, material handling cost, larger carpet area is achieved due to slimmer pillars and also reduces the overall time of construction.
Yes Radha 550 TMT Bars are sold in retail shops by pieces.
Radha 550 TMT Bars in pieces offer you the following advantages:
- Guaranteed weight in each piece.
- Procure exact pieces as recommended by structural engineer or architect.
- Avoids wastages in sites as exact number of pieces is purchased.
- Guarantees customer satisfaction by reduction in delays and reduces labour cost.
Find the following on the Bars
- Radha TMT 550 stamp on every meter of bar
- Blue Radha TMT 550 strip on every bundle
- Blue Radha TMT 550 tag on the material proves the genuineness of Radha 550 TMT Bars .
So watch out for above 3 things while purchasing Radha 550 TMT Bars .
Few Tips to evaluate while purchasing any bar to give you
the best quality and deal
- When bent, bar should bend smoothly.
- Transverse Ribs or Lugs of the bar should be sharp. So that it bonds strongly with the cement.
- Use TMT bars made of primary raw material i.e, MS Billets as it guarantees endurance to heavy loads.
- Before purchasing one should check the price of Radha 550 TMT Bars on the Radha 550 TMT
- Comparable weight of bar per meter should be according to ISI standards.
- Cross check when you weight the bar.
- Bar should be of any ISI & ISO 9001:2008 certified company only.
- Every meter length of bar should bear company’s stamp.
- Every bundle should carry company’s Tag and strap on it
