TMT steel bars are used for core structures of all constructions, irrespective of the project size. TMT bars are made of specially treated steel to make it corrosion-free and highly ductile. These bars are required to strengthen the structure and the whole construction to ensure security.
Hence, it is important to choose a TMT bar with guaranteed quality. Poor-quality TMT bars may weaken the construction and compromise security. To ensure the quality of TMT bars, Every TMT steel company has to go through certain tests and get certified the product. Let us provide an overview of the certification and qualities to consider before choosing a TMT steel company for your construction.
The government has a defined standard for TMT steel bars. The TMT steel company that passes this standard test will get certified by the government. This certificate is called the ISI certificate. Some of the important parameters of the ISI test are tensile strength, elongation, yield strength, and chemical composition. The ISI certificate ensures that the TMT bar is treated to resist corrosion, earthquake, high pressure, and temperature fluctuations, and is ideally ductile for construction.
The ISI certification will provide the actual information about the TMT bar. However, you need to check some key points while looking for the ideal TMT bar. We have explained the key factors that you should consider while checking the certification of the TMT steel Company and bars.
The grade of the TMT bars is an important factor to check before settling for one. TMT bars are available in different grades like Fe 415, Fe 500, Fe 550, and Fe 600. The higher number of TMT bars are made of high-grade steel, and the lower number indicates the opposite.
The lower-grade bars like Fe 415 are ideal for small construction and Fe 500 is ideal for high-rise buildings. Any bars above Fe 500 are ideal for huge constructions like bridges, dams, etc., as they need to handle extreme weight and pressure.
Flexibility and weldability are very important for strong constructions. The ductility of a TMT bar is responsible for its flexibility which ensures that the bar will bend under pressure without breaking or losing its strength. So you must check the level of ductility of the TMT steel company or bar.
The weldability ensures the TMT bar can be joined securely with other bars during the construction. The more weldable the bar, the more strong the bond will be and will ensure strong construction.
Corrosion of TMT bars can damage the construction, develop cracks in concrete, and may destroy the construction with time. This is why you must check the chemical composition the TMT steel company has used for the bar. The higher percentage of copper, phosphorus, and chromium will provide higher corrosion resistance.
To ensure the security of the construction you must check the level of earthquake resistance of the TMT bar. The ductility of the TMT bar helps being earthquake resistance. The ISI certification will provide clarity on the parameters.
The reputation of the TMT steel company should be considered along with ISI certification while choosing it. Customer reviews on digital platforms and testimonials of reputed clients can be helpful to ensure the reputation.
Natural calamities are unpredictable and environmental causes for weakening the construction are unavoidable. You must be prepared to protect your construction. As TMT bars are the core of the construction, you must choose the right one. This is why it is important to choose the best TMT steel company for your construction and you must check the certification the company has.
