6 Factors of Choosing the Best Steel Bar for Construction

Points to consider while choosing the best TMT bars

The overall growth and progress of any nation is directly linked to the infrastructure sector. In a country like India, infrastructure facilities ranging from roadways to IT parks, educational institutions, hospitals, entertainment hubs, and more have a direct impact on the nation’s economy and raise living standards.

The process of constructing any of the above-mentioned infrastructure facilities is complex and requires thorough planning. Additionally, it is extremely important to make sure that the building materials used are of top quality. Some of the key building materials used in construction are TMT bars, bricks, concrete, wood, and sand.

Steel rods used for construction; also known as Thermomechanical treated bars play a vital role in determining the strength and durability of the structure. Therefore, it is important to buy the best TMT bars available in the market to build stronger and safer structures that last generations.

Factors That Need to be Assessed Before Buying TMT Steel Rods for Construction.

• CHEMICAL COMPOSITION -  The chemical composition of elements such as carbon, sulphur, and phosphorous dictates the strength, level of flexibility, and bendability of the TMT bars. Therefore, it is always important to check the chemical composition of the TMT bars before purchasing.


• GRADE OF STEEL –  The grade of steel used in the manufacturing process has a direct impact on the strength of the TMT bars and eventually the strength and longevity of the structure built using the said TMT bars. TMT bars come in various grades, ranging from Fe 450 to Fe 550 D.
  

  The higher the grade of steel, the higher the strength.



• TENSILE STRENGTH & DUCTILITY -  Highly ductile steel rods are ideal for all types of construction projects. They are easy to bend and possess increased shock withstanding capacity. This ensures protection against natural calamities such as earthquakes.
  In addition to the above, high tensile strength brings along with it the
  
  • high level of flexibility.
  • Easy bendability and weldability
  • High yield strength
  TMT bars of 550 D grade promise higher ductility and tensile strength in comparison to other TMT bars available on the market.


• RESISTANCE–  Steel rods that are resistant to corrosion are highly ideal for coastal regions. Similarly, TMT bars that guarantee fire and earthquake resistance are preferred as they play a vital role in safeguarding the structure in times of calamities.
  In short, the best TMT rods are resistant to corrosion, fire, and earthquakes.


• CERFTIFICATION –  The best steel rods for construction are those that have been certified by recognised national and international organisations such as BIS and SCG. The certifications assure top-notch quality alongside safety against corrosion, earthquakes, and fire.


• BRAND REPUTATION–  Another aspect to be considered while purchasing TMT bars is the brand image and reputation. Brands with greater quality are highly preferred by architects and civil engineers. This ensures greater reach and visibility.
  Additionally, well-known brands are available across regions and supplies are round the clock.
