How Are TMT Bars Prepared For Construction Projects?

by Avinash Kaushik Media and Marketing Manager

TMT bars are extensively used in a lot of construction projects and are now considered the cornerstone of the modern construction requirements. They are used in making beams, slabs, columns and all load bearing structures as well as their belongings.

Purpose of TMT Bars

· Provide core strength to the building skeleton and beams
· Withstand large loads to provide a scope of further building higher layers
· Provide protection from extreme vibrations like earthquakes, high speed winds and tremors
· Flexibility to provide renovation to the outer structure of the building

How Are They Prepared?

In order to meet the current requirements of construction, the steel manufacturers use special methods to build steel bars which are known as TMT Bars. TMT stands for Thermo Mechanical Treatment which is a unique metallurgical process. The TMT manufacturers in India manufacture these based on the approved standards of Bureau of Indian Standards to provide the best products.

Fe 500D and Fe 500 are considered to be the best materials to make TMT bars in India and most of the construction of buildings. They provide enhanced protection against earthquakes and other types of natural disasters. TMT Bars made of Fe 500D and Fe 500 denote minimum yield stress. The term Fe denotes iron and D shows that the bars come with higher ductile properties. TMT Bars that are best for construction in India have low percentages of phosphorus and sulfur which are the evil elements of construction. Higher amounts of sulfur can cause cold shortness and make the steel very brittle which even with the slightest vibration can break easily.

They also suffer from hot shortness in the presence of sulfur in the TMT bars and the melting point of steel also lowers causing failure under high temperature or pressure conditions. The overall carbon percentage in these metal bars is also kept very low to promote weld ability and ductility of steel.

These steel bars are manufacture d by best TMT bar manufacturers in India under heavily regulated manufacturing process that makes them quite flexible and easily bendable.

Concrete shares an important bond with steel and thus it is important to combine both to get the best quality structure for construction. Concrete is characterized by great compressive power along with low ductility and tensile strength. Thus, as it combines with TMT Bars it provides more tensile strength and ductile skeleton for the framework. The provide freedom of designing to the builders with their bend ability.
