Beam a foundation joint for a better and long-lasting home!
The History of Beam Construction for Homes
The beam is a reasonably level structure that is developed to support a load. It is because of this reason; it is one of the most critical frameworks for any home. Over the years beams were developed using the finest quality wood. This ensures the durability and structural integrity of the homes. However, with the dawn of the last century, a major shift was seen in beam construction, with users and organizations shifting from wooden beams to concrete beams. With the introduction of the concrete beam, a sharp rise in TMT Bars usage was seen all across the globe and the same inference stands for India as well.
A Shift in Beam Construction Dynamics
One of the major reasons behind this dynamic shift was completely based on the fact, that wooden beams were easily affected by termites. Besides this reason, over a period of time, the wooden beams would also trap moisture, which not only affected the beams by allowing them to rot but would also result in the development of damps on the walls. This directly affected not only the integrity of the beam structure and its surroundings but also the integrity of the entire building. As a result, the moving trend towards concrete or cementitious beams came into existence.
The New Era of Beam Construction and Discoveries
However, the journey to create stronger and long-lasting beams was still a complex process despite this change. One of the major reasons behind this is finding the right TMT bars that would support the weight of the beam, without exerting overhead pressure on the surrounding walls. Through the transverse of experimentation in the past 50 years, many variants of TMT bars ranging between 12mm and 25mm have been tested and tried for beam creation. However, with a modular structure of beam where 4 TMT bars are tied in a loop, lightweight is the most important criterion for beam creation. It is because of this reason, the 12mm bars were found to be the ideal solution for beam creation. The internal findings thus, reflected an individual 12mm TMT bar weight to be 0.890 kg/m. Thus, the development of a strong beam for a home to weigh around 3.56 kg/m for an individual beam’s TMT structure!
The Challenges in the New Era of Beam Construction
With the knowledge gathered from this tested and tried method of different TMT bars multiple arrays of approaches were made to ensure perfection using 12mm TMT bars. However, despite these efforts, many a time beams failed to meet the desired quality. The main reason behind this was the poor quality of TMT bars, which were either overweight or made up of scrap iron that easily cracked under pressure, corroded away in time, or catches rusting. Hence it was extremely to identify TMT manufacturers who would supply the best TMT bars in India.
That is why in this segment of our article we have accumulated information about TMT that makes them the best in the nation. Let’s walk you through the different factors that contribute towards manufacturing top TMT bars in India, directly contributing towards the building of strong beams for your home.
Different Factors of TMT that Help in the Construction of Strong Beams
Raw Material of TMT
The Best Quality TMT bars in India are manufactured from Virgin Iron Ore. It is because Virgin Iron Ore is the source of raw material for producing top–quality TMT bars in India. It is because TMTs manufactured from scrap or reused iron are of poor quality and ends up developing rust, and cracks, while being vulnerable to corrosion. This directly impacts the strength and longevity of the beam construction. Hence, the Best TMT manufacturers in India always prefer to use Virgin Iron ore to produce TMT bars.
Process of Manufacturing TMT
The manufacturing process is one of the most critical factors in developing good-quality TMT bars. It is because the manufacturing process determines the strength and flexibility of the TMTs. That is why the best TMT bar manufacturers in India use a controlled process and the latest Thermex technology to manufacture TMT bars. This, in turn, provides the TMTs with increased strength, while reducing impurities. Further with the use of the latest technology the TMT bars can achieve better ductility, and improved ability to absorb energy. Allowing the beam structures constructed using TMTs to be more resistant to natural hazards like earthquakes.
The Grade of the TMT Manufactured
In India, there are many different grades of TMT bars that are presently available in the market. This varies between Lower Grades to Higher Grades. These grades of the TMT Steel determine the elongation of the bars. According to Indian Standard Deformed Steel Bars and Wires for Concrete Reinforcement Institute (IS: 1786/2008); lower grades TMT Bars have Lower Strength and High Flexibility whereas higher grades TMT Bar have Higher Strength & Lower Flexibility. That is why the best TMT bars in West Bengal are manufactured keeping in mind that the TMT bar provides the right balance of flexibility and strength when you plan to use TMT for construction. As per research conducted by “Indian Standard Deformed Steel Bars and Wires for Concrete Reinforcement Institute” under (Indian Standard code 1786 & 2008); a TMT bar that maintains the right balance of flexibility and strength, signifies the minimum yield stress in MPa (tensile strength), and better elongation. Further, these top-quality TMT bars provide extreme weldability, ductility, and bendability which are far superior to all other TMT bars in India. Thus, facilitating the construction of strong beams for your home!
The Design of the Ribs in TMT
The design of the TMT Ribs plays a crucial role in providing a strong anchorage sheath between the TMT and the cementitious material. Thus, allowing the concrete formed with the help of the TMT ribs to have a better grip. This in turn improves the stability of the beams by a huge margin, when compared with poorly ribbed TMTs, which often end up getting badly damaged during natural calamities like earthquakes, cyclones, etc. That is why the best quality TMT bars in India select TMT ribs that are approved by “IS 1786”. It is because these approved ribs have been designed keeping in mind natural calamities that may affect the integrity of the building. Since India falls under a high seismic zone with a devastating history of earthquakes “IS 1786” approved ribs are a must when planning to use TMTs for beam construction purposes.
Corrosion Resistance
TMT bars are the pivotal component of beams that defines the integrity of the constructed structure. That is why it is important to select TMT bars that are resistant to corrosion. It is because TMT bars are often exposed to moisture, rainfall, and other weather conditions over a long period of time. This exposure can result in corrosion of the TMT’s steel, which can directly affect the integrity of the beams, by making them weak from the inside. Hence the top TMT bars in India are produced keeping in mind the TMTs are resistant to corrosion. This can also help in supporting beams even in places with heavy rainfall and also places prone to flood besides earthquakes.
Ductility
Before purchasing TMT, it is of prime importance to check the ductility of the TMT bars. The ductility reflects the elongation capacity of the TMT bar, which indicates the ability of the TMT bars to be elongated or stretched using external force without impacting the integrity of the bar. Hence the top TMT bar in India ensures that the TMT produced has better elongation capacity/ductility ensuring stronger beam construction for homes.
Weldability
TMT bars are often required to be cut, reshaped, and welded into places based on beam designs. Hence it is important to have TMT steel that allows an easy welding process. Further, if the TMTs are not manufactured under properly controlled thermomechanical treatment they end up requiring pre and post-welding treatment. This, in turn, increases the cost of the TMT bars. Hence the best TMT bar in India provides easy weldability to ensure stronger and sound beam construction.
These are some of the major factors that consumers should always keep in mind when planning to purchase TMT bars for the construction of strong beams for their homes.
