What are TMT bars and what are the different types? PowerPoint PPT Presentation


TMT bars are extensively used in different kinds of civil construction projects, therefore they form the cornerstone of modern city life. They are used for making building, beams, slabs, columns and also other kind of structures that bear the live load of people as well as their belongings. Being the core strength of all kinds of structures, the TMT bars are needed to be capable of withstanding large loads.

What are tmt bars and what are the different types

What are TMT bars and what are the different types?

TMT bars are extensively used in different kinds of civil construction projects, therefore they form the

cornerstone of modern city life. They are used for making building, beams, slabs, columns and also other

kind of structures that bear the live load of people as well as their belongings. Being the core strength of

all kinds of structures, the TMT bars are needed to be capable of withstanding large loads. They should

also be able to offer protection to a structure against earthquake and windstorms. Poor quality

materials like cheap steel bars generally contain very high levels of different unknown elements that can

be quite harmful for construction. In other words, these steel bars lack the requisite physical and

chemical properties that would make them appropriate building materials.

In order to meet up to the advanced load handling requirements of modern steel bars, special methods

are used to create products that are referred to as TMT bars. TMT bars are prepared by using a unique

metallurgical process called “Thermo Mechanical Treatment”. The TMT bars are technically approved by

Bureau of Indian Standards which makes them suitable for construction and building projects. The Fe

500D and Fe 500 are certain better quality TMT steel bars which can be purchased from the market

today. Most of the current building projects in India are carried out by the Fe 500D and Fe 500 TMT Bars

as they can offer enhanced protection against earthquake and other types of natural disasters.

In the TMT bar types Fe 500 and Fe 500D, the 500 denotes minimum yield stress, the term Fe indicates

iron and D shows that the bars come with higher properties of ductility. The TMT steel bars have low

percentages of phosphorus and sulfur which are quite harmful for steel specimens meant to be used in

construction. Higher phosphorus can cause “Cold Shortness” that makes the steel brittle under very cold

conditions which can lead to cracking. Higher sulfur content can lead to “Hot Shortness” that lowers the

melting point of the steel, thus leading to eventual failure under very high temperature conditions. The

overall carbon percentage is also kept low in these bars for improving the weldability and ductility of

steel.


What are tmt bars and what are the different types

Steel manufacturing companies in India craft these bars under heavily regulated manufacturing process

that makes them quite easily bendable. The TMT Saria steel bars share a special connection with

concrete which is used for all building projects. Concrete is characterized by great compressive power

along with rather low ductility and tensile strength. Thus when it combines or fuses with the TMT steel

bars; concrete gives rise to highly tensile and ductile end results. Every Primary Producer of Steel in India

regularly manufactures Fe500D and Fe500 TMT bars, and while the tensile strength stays the same for

both these types of TMT bars, the Fe500D variant comes with higher ductility. Ductility describes the

ability of a material to easily deform and adapt as it is put under stress with tensile load within a

construction unit.
