Whether it’s your dream home or a shopping mall, using high-quality TMT bars for construction is always crucial for the safety and longevity of the building. For this, you’ll need TMT bars that will hold the concrete together and help maintain the structure of the building for years to come. Precisely why, the initial step in building construction is to choose and source the best quality TMT bars from a reputed manufacturer.
Opting for substandard TMT bars from the market can be a cheaper option but comes with costly after-effects. On the other hand, going for TMT steel bars from trusted steel distributors is the best option, so that the quality of the steel bars is never compromised.
While choosing TMT bars for your construction project, the below-mentioned features need to be considered:
The higher the grade, the better the quality of the TMT bar. There are several TMT bar grades available to choose from - TMT Fe 500, Fe-500D, Fe-550, Fe-550D and Fe-600. High-grade TMT bars like 550D have greater yield strength, tensile strength and elongation when compared to low-grade TMT bars. Therefore, high-grade TMT bars are well-suited and mostly used for tall and massive constructions since they can handle greater stress and pressure and are more resistant. Whereas, residential buildings and smaller structures with lower load-bearing needs can use TMT bars grade like 500D.
The high ductility of TMT steel bars is crucial to increase their bendability to suit your requirements as well as strong enough to resist the weight and pressure that it would be subjected to after construction. High-quality TMT steel bars such as Kay2 Xenox offer high bending and re-bending performance to avoid cracks, even when they are bent at an angle of 90 degrees or more. These TMT bars are also suitable for seismic zones where they need to stay intact, even under high-stress conditions.
The ductility and elongation capability of a TMT bar are closely related properties that represent a material's ability to deform under stress without breaking. Ductility is the range to which a material can be deformed without fracturing. On the other hand, elongation is the deformation amount that a material undergoes before it breaks. The elongation capability of a TMT bar is influenced by several factors, including its microstructure, chemical composition and processing conditions. Generally, steel grades with higher levels of carbon and other alloying elements tend to have lower ductility and elongation due to their greater strength and hardness. Conversely, steels with lower levels of carbon and alloying element contents are more ductile and possess higher elongation.
TMT steel bars are destined to encounter moisture during construction. Low-quality bars can easily rust and corrode which would lead to weakening the structure. Therefore, it's crucial to use only high-quality TMT steel bars like Kay2 Xenox. These bars are corrosion-resistant and moisture-resistant which help to retain the structural integrity over time. The new-age technology employed in the design and the compact ribbed pattern enhance corrosion resistance and bond strength, contributing to the overall life span of the construction.
TMT bars are often exposed to high temperatures during construction projects, especially in industrial regions. These designs become possible as high-quality TMT bars can retain their strength and stability when exposed to extreme temperatures. In this scenario, Kay2 Xenox TMT bars dominate the market as they can retain 80% of yield strength at 300°C and 40% at 500°C when treated with high melting point substances. This makes Kay2 Xenox highly suitable for construction projects at fire susceptible areas.
Dimensional accuracy is critical for TMT bars' uniformity and quality control. Precise dimensions form the basis of manufacturing high-quality TMT bars such as Kay2 Xenox. Meeting BIS certifications, Kay2 Xenox bars ensure quality as well as provide application benefits and design advantages for a wide range of construction needs.
Having a full understanding of the technical specifications and performing a number of visual inspections can help you identify high-quality TMT bars. Below are some inspection tips that will help you identify the best TMT bars for your project:
This is an important point to consider while choosing a TMT Bar for your construction project. Always check the brand profile and ISO & ISI recognition. It has always been said to go for popular brands having the BIS certification which ensures the proper quality.
As per the design needs of the concrete structure, the builders need to bend the TMT bars during the TMT bars application. If the bars are of high quality, they will not show any signs of cracks while bending. Hence, inspecting for flexibility is important for the best TMT bar constructions.
The modern manufacturing process uses Thermo Mechanical treatment with a water cooling system, which offers the bar greater flexibility and strength.
The weight of these TMT bars must be in line with the ISI standards. Every meter of the bar should weigh the same as stated in the manufacturer’s specifications.
Every meter length of the TMT bars should have the company symbol. High-quality TMT Bars must be free from rust and look newer than ever. Also, the tip of each bundle should be of equal lengths.
Your construction structure is as good as the TMT bars you use for its construction. Hence, using the best quality bars is crucial for your project’s longevity and safety. Kay2 Xenox TMT bars offered by Kay2 Steel encompass all the quality standards required in a high-quality TMT bar, which will help you build a dream structure with zero compromises and a lot of pride.
