- 1. Frequently Asked Questions on Reinforcement Bar (FAQ’s on TMT ReBar)
- 2. What is Thermo mechanical Treatment? Once the molten iron passes through the basic oxygen furnace and convert into steel. Thermo mechanical Treatment (TMT) or Thermo mechanical processing is an architectural process that unifies hardening and heat treatment into a single process. The quenching process makes the low carbon steel bars softer in core and outer surface becomes hard with prominent ribs. This process make the steel bar highly ductile and make them ready for all type of construction purpose.
- 3. What are the Usage of TMT Bar? TMT bar is the main component in Reinforced Cement Concrete (RCC). For all type of structures RCC ensures the strength and longevity. Be it your Home | Multi Storied Building | Commercial Building | Power Plant | Bridges etc. TMT bars are highly ductile therefore it can bend upto 180 degree without any damage. In order to secure all type of construction from natural disaster such as earthquake you need to choose the best quality TMT bar that provides the right combination of Strength and Flexibility and protect your structure during an earthquake.
- 4. What are the steps for Manufacturing TMT Bar? TMT Bar Manufacturing has essential 3 steps: Step 1 Step 2 Step 3 The hot rolled bar leaves the finishing mill and rapidly quenched by the Thermex/Tempcore process. The quenching process converts the billets layer into martensite and shrink. Shrinkage process pressurize the core and helps to form the accurate structure, the core remains hot. The bar leaves the quench box with temperature gradient. Gradually as the temperature goes down heat flows from bars centre to its surface. Bars heat and pressure correctly tempers an intermediate ring of martensite and bainite. The final step is known as Atmospheric cooling. Right after the quenching automatically tempers the austenitic core to ferrite and Pearlite on the cooling bed which is having strong, tough, tempered martensite in the surface layer of the bar, an intermediate layer of martensite and bainite, and a refined, tough and ductile ferrite and pearlite core.
- 5. Benefit of using Corrosion Resistant Steel Bar? Benefits of Corrosion Resistant Steel bars (CRS)are listed below High Yield Strength Highly Ductile and easily weldable Longevity Material Handling cost is nominal. No extra care needed. Fabrication is easy with this corrosion resistant TMT bar It can bend easily No extra maintenance precaution needed Highly recommended to use in Seismic Zones In Seaside, highly humid areas, industrial use where saline water/gaseous emission will come in contact only Corrosion Resistant steel can be used To know more visit: https://goo.gl/3edrbV
- 6. What is an Integrated Steel Plant? A State of the Art Integrated Steel plant means it has the ability to perform every step for manufacturing the steel. From processing the raw material to final product that include: Raw Material Processing Iron Making with Blast Furnace Steel Making Continuous casting Producing Rolling Mills, Bars, wires etc. An Integrated Steel plant must have DRI Unit, Electric Arc Furnace, Continuous Billet Casting Unit, Rolling Mill.

- 7. Is TMT steel Bars are Cost Effective? TMT Steel bars weight are lesser than Traditional Steel Bar. It is essentially for it's tensile strength. Heavy weight products are stiff in nature and easily cannot move or exchange the energy. Be it steel bar or any other kind of material. Steel TMT rods save upto 17% of steel over other steel rods. Steel requirement idea for Fe 500D TMT Bar To know more visit: https://goo.gl/FoLhjU Type of Structure Steel requirement for Fe 415 Steel requirement for Fe 500D Saving in Steel by using Fe 500D RCC Foundation 1 metric ton 0.83 metric ton 1.70 kg p/mt Basically Higher Tensile Strength = Lesser Consumption of Steel
- 8. Why Fe 500D TMT Bar is best? Fe 500d TMT bar are considered to be best because D = Elongation. As per Indian Standard in this new standard has been introduced. BIS (Bureau of Indian Standard) brought down the amount of Carbon, Sulphur and Phosphorus values to increase its ductility. In Reinforced Cement Concrete (RCC) Fe 500d provide high compressive force. That is why it widely accepted for all type of construction purposes. Fe 500D TMT bar comes with the combination of Strength and Flexibility that helps to protect your home during an earthquake.
- 9. Why Shyam Steel TMT Rebar is best for your Home? Shyam Steel is the pioneer steel manufacturer and supplier in India. Over 60 years they are contributing to India’s growth. Shyam Steel’s flexiSTRONG TMT Rebar is widely accepted nationwide. They adhere 5 main factors that helps to differentiate from others. Total Quality Management Inspection Control Assurance Excellent After Sales Support Manufacturing Excellent with State of the art Steel Plants Employee Contentment Social Responsibility
