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 can 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 among 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, and 32 mm. All the bars manufactured by RADHA TMT use the Thermex process.
• German Thermex technology, the 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 the 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 possess precise and uniform parallel rib pattern s 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 with every bar as the roll pass in the finishing mill stand is not overused , thus ensuring the final product delivered to the is of extremely high quality.
Radha 550 TMT Steel Bars have a precise and uniform parallel rib design which results in superior mechanical properties as compared to the other ordinary Steel Bars on the market. Parallel Ribs on Radha 550 TMT Bars are produced with the help of Sparkonix CNC machine in a state -of the art high speed automated rolling mill machine which give s 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 possess uniform and precise parallel rib pattern, which ensures excellent bonding with concrete, resulting in a 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 a 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 an earthquake . – a boon for ductile constructions in the seismic zones.
Weld-ability: Radha 550 TMT Bars have low carbon equivalent and are directly related to hydrogen-induced cold cracking which is the most common weld defect for steel. A higher concentration of carbon and other alloying element tend s to increase hardness and decrease the weld-ability.
Corrosion Resistant: Radha 550 TMT Bars have minimum or negligible residual stresses with 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 a high UTS/YS ratio which signifies that steel is capable of elongating to a large extent when loaded beyond the yield point. 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 a super strong construction.
Cost Savings: Radha 550 TMT Bars have a high UTS/YS ratio and high elongation which results in lesser consumption when compared to the other TMT of the same sectional properties which have 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. The higher the strength, the 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 costs and material handling cost s, 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 in pieces
Radha 550 TMT Bars in pieces offer you the following advantages:
• Guaranteed weight in each piece.
