The Role Of Quality Control In TMT Bar Manufacturing

The construction industry in both India and abroad is dominated by thermomechanically treated bars. TMT bars manufactured through rapid heating and quenching are known for their incredibly high tensile strength, durability, ductility, weldability & corrosion resistance. Now used for all critical residential, commercial and industrial structures, these reinforcement steel bars are spearheading construction and standing out as the epitome of quality and reliability.

Thus, for such a critical construction material, the importance of quality control is immense. Quality control of manufacturing is one of the key aspects that differentiates one supplier from another. The industry standards of quality control entail immaculate processes- without which the safety and quality that TMT bars are known for, would all lack due credibility. This article aims to explore these processes that every trusted TMT bar manufacturer deploys during their manufacturing stint and discloses in front of you its impact on the final product that you end up receiving.

Essentials Of Quality Control

Go through the pointers mentioned below to understand the steps that quality control of manufacturing involves when it comes to creating the best thermomechanically treated bars in the country:

• Checking Dimensions: The first step before the steel bars are sent rapid heating in blast furnaces and then quenching is to check the dimensions and the weight as per the requirement of the project. The specifications differ according to the project and the steel grade concerned.
• Inspecting The Surface: If the surface of the TMT bars is seen to have cracks or other kinds of fissures, then they are immediately held back. This stops wastage and also prevents your safety from getting jeopardised.
• Chemical Composition Testing: The chemical composition of each reinforcement steel bar is tested to ensure consistency and also to see if it matches the concerned steel grade.
• Tensile Strength Test: This is a critical test. If the bars fail this, then they are not sent through for further processing. TMT bars are known for having a high tensile strength that can withstand extreme loads and stress. This test is a measure of that.
• Bend & Rebend Test: The bend or rebend or bendability or flexibility test is nothing but a thorough process that is conducted to ensure how ductile these bars are.
• Analysing The Microstructure: The microstructure of any TMT bar is really what separates them from other reinforcement steel bars. The analysis of this microstructure which has a soft ferrite core and a tough outer surface is thus key.

Benefits Of Stringent Testing Methods

Now, let’s understand the impact that all of these aforementioned processes have on the final product that you receive and get protection from for decades and generations:

• Improved Safety: Stringent quality control of manufacturing ensures a greater quality of TMT bars. This improved quality refers to the ease of process during construction and transportation, almost zero wastage during the entire process, better strength, more corrosion and seismic resistance and thus longevity and durability.
• Longevity: Better quality control measures mean better re-bars. This means a complete assurance against wear and tear from the forces of nature and pollution. A manufacturer that does its quality check diligently is bound to produce steel bars that are capable of making a building last for ages.
• Cost Effectiveness: Better quality bars guard you against frequent repairs, renovation and maintenance. This means that it is a one-time investment. You do not have to spend anything in the long run.
• Better Property Value: Buildings and key infrastructure that have been constructed through checked and judged materials provide you with a lot of monetary value. An architecture that’s in the right condition and has lasted for a long time will have a much higher market price subject to sale than a property that’s decaying over time.
