Types of steel reinforcement Bars | TMT Bars | Hot Rolled Deformed Bars | Cold Rolled Steel Bars |

Different Type of Steel Reinforcement Bars
Different types of steel bars are used in Concrete Structures. Reinforced Steel bars are used to strengthen the concrete structure that makes it long lasting.
5… Types of Steel Reinforced Bars are used in Cement Concrete
1.Hot Rolled Deformed Bars
2.Cold Rolled Steel Bars
3.Mild Steel Bars
4.Twisted Steel Bars
5.Welded Steel Wire
Hot Rolled Deformed Bars
Hot rolled deformed bars are also known as Thermo mechanically treated bars or TMT Bars. In RCC (Reinforced Concrete Structure) TMT Bars are commonly used for its superior tensile strength. The Ribs on TMT Bars provide superior bonding in Cement Concrete. Best quality TMT Bars has a tensile strength of 64000 psi (PSI - Strength of Concrete is measured in pounds per square inch).
Cold Rolled Steel Bars
Cold Rolled Steel bars looks similar as Hot rolled bars although these are made at room temperature. These bars consists poor strength and easily bendable. Cold Rolled bars are almost obsolete from the market though these are used for some construction that does not need much tolerance. It carries tensile strength upto 60000 psi.

Twisted Steel Bars
Twisted Steel Bars are also known as Prestressing tendons. These are comprised of different wires almost 7 wires spun together into a strand. Twisted Steel Bar carries high tensile strength upto 270000 psi. These are mainly used on braces of scaffolds for prestressing Reinforced Cement Concrete. Its high tensile strength makes it conceivable.

Hey man... thank you. I'm not very familiar with steel reinforce bar but I have found in some literature that TMT is differ from hot rolled deformed. Also I would like to know what standard designation does India use for steel reinforce bar?
