8 Factors to Check TMT Steel Bars before Buying

One of the most significant constituents of the construction industry is ‘TMT Steel Bar’. 

They are widely used in steel bars in the structural system of the construction industry because of the following features:

• High Tensile Strength
• Better Bending Capability
• Power to elongate

The structural strength of the steel bars depends upon various factors such as building material quality, design, etc. Thus, it’s important to choose the right quality of TMT steel bars, be it a construction for a dream home or commercial building.

This guide will provide the exact information needed to buy the right TMT Steel Bars for a strong construction and a stable structure to the building.

Several things to verify before buying TMT Steel Bars for construction:

Grades of TMT Bars: 

Strength of TMT bars depends on its grade. The higher the grade, the stronger it is. The various grades of TMT bars are- Fe-415, Fe-500, Fe-550 D, Fe- 600,Fe-640,CRS-500, CRS-550D, CRS-600, etc.  The higher grade TMT bars are used for making the roofs and floors(core of the building), industrial and large-scale commercial works, whereas the lower grade TMT bars are usually used for making decorative structures, balconies, railway, etc. Therefore it is mandatory to check the grade that fits the category of use.

Process of Manufacturing:

This is a significant process in making standard quality of TMT bars. With the advancement in technology, the modern process of manufacturing has been introduced, omitting the usage of older technologies. These technologies ensure the strength of the TMT bars.

Flexibility:

High quality TMT bars withstand stress for a long period of time ensuring that it doesn’t develop cracks or breaks upon bending due to activities like earthquakes. TMT bars with high flexibility and bend-ability helps to regain their shape and form by not entertaining cracks which further creates structural integrity problems. Thus checking flexibility before buying is important.

Capacity to Elongate:

It indicates the ductility of the TMT bars. The more ductile a bar is, the more is the elongation capacity further saving the cost of transport during construction, lasting for a long period of time.

Corrosion-Resistivity:

There is always a higher chance for the TMT bars to develop corrosion as they are exposed to moisture and other weathering conditions which can cause severe damage to the buildings. Therefore, it’s important to make the TMT bars resistive of corrosion, especially in heavy rainfall or flood prone areas. Anti corrosive TMT bars provide damage resistance to the structure. They are either CRS grade or epoxy coated.

Certified by Brands:

It’s important to check the brands of TMT bars being certified by BIS or ISO as they ensure the security and quality of the standard of the TMT steel bars. 

Quick-Test at a Glance:

An overview before buying is mandatory. Checking the logo of the manufacturing brand in each TMT bar, ensuring that the bars are rust-free, a quick glance at the end of each bundle should be equal in length, and also looking for the seal of the manufacturer in it.

Comparative study:

Comparing two or more suppliers before purchase helps to get an idea about the quality, product, prices and also makes it easier to choose for purchase.

These above mentioned points help to make a better decision by choosing the suitable TMT steel bar with longevity of the construction.
