TATA Tiscon Steel Rebars (TMT)

Reinforced steel bars or Rebars are used to help concrete withstand tension forces. Concrete by nature is sufficiently strong to compression forces, however the tension forces can crack concrete. Therefore with the combination of reinforced steel bar and its concrete strength and texture, it can make the main structure withstand the tension forces hence strengthening the buildings. The deformed pattern on a rebar will help the concrete to adhere to the reinforcing steel surface at even greater level. It's widely available in different form. 

Deformed Bars

Deformed bars are used to reinforce high strength concrete because of their high strength and their ability to hold on to the cement. The deformed bars are made in accordance with TIS24-2548 (2005) SD30, SD40, SD50 from 6-40mm at 10 and 12m long. Production of re-bars begins with charging reight porportion of steel scrps, high quality lime and coke into and Electric Arch Furnace or EAF. The mixures are melted by energy generated by electric arc. During melting process, the steel undergoes complex chemical and physical processes. When temperature and chemical compositions are correct and verified by laboratory test, the molten steel is tapped into a ladle and sent to the continuous caster where high quality billets are produced. The quality billets are later reheated to 1050 degrees celcius prior to being rolled to the desired size and quality. The products which can be produced through this process are deformed bars SD 30, SD 40, and SD 50 accordance to TIS 24-2548 (2005) from 6-40mm and round bars SR24 in according to TIS 20-2543 (2000) from 6-34mm diameter.

Round Bars

Round bars are suitable for using as reinforced bars for small and medium building such as commercial buildings and houses. The round bars are made to the TIS20-2543 with standard size 6-34mm at 10 and 12m long.

What's the difference between EAF and IF production process of Rebars

TATA Tiscon steel in Thailand is currently made of EAF process.
