Construction is one of the largest sources of carbon emissions in the world. From the extraction of raw materials to transportation and fabrication, every step in the building process has a significant impact on the environment. However, for home builders, architects, and contractors who want to do their part in building green, the procurement process, especially steel procurement, has a greater impact on the environment than most people think. Steel selection has become much more than just a matter of building safety. It has become one of the most effective ways to reduce the carbon footprint of a building project.
How steel choice affects your carbon footprint
Conventional steel production is a process that requires a great deal of energy. The blast furnace process for converting iron ore into steel and the use of coke for the same process result in the emission of a tremendous amount of carbon dioxide into the atmosphere. The electric arc furnace process for melting steel scrap and making steel from recycled steel billets results in a reduction of up to 70 percent in the emission of carbon dioxide into the atmosphere compared with the traditional process. Manufacturers who use 100 percent refined steel billets and invest in an energy-efficient rolling process are now producing steel with a reduced footprint on the environment. For builders who care about the environment, it is just as important to ask a supplier about their methodology as it is about their grades.
Higher grade steel means less steel used
One of the most ignored methods for lowering the carbon footprint of a building is using higher grades of TMT bars. While evaluating the TMT bar properties in Tamil Nadu or in South India as a whole, there are instances when people fail to grasp the fact that a higher value of yield stress in TMT bars means that the structural design of a building requires a lower quantity of TMT bars for a similar structural capacity. The use of Premium TMT steel bars in Tamil Nadu rated as Fe550D enables designers to minimize the quantity of TMT bars used in a building’s structural design while ensuring complete safety.
Durability is sustainability
Carbon footprint is not only about what happens during the process of creation; it is also about how long a structure lasts. A building that needs major structural repairs after twenty years or a building that needs to be demolished and rebuilt has a huge footprint in terms of its carbon burden. Steel that has high resistance to corrosion, maintains its mechanical properties for decades, and has a high bondability with concrete has a high potential for structures that can stand for generations. Thus, the best quality TMT steel bars in Kerala are created with a high potential for long service life rather than high short-term strengths. The best way to reduce carbon footprint is during the creation of the material in the factory.
Green certifications as a quality signal
With the rising popularity of green building norms in India, measured along the IGBC and GRIHA scales, the materials used in the construction industry are also being put under the microscope. Steel producers who boast of environmental credentials are not merely engaged in a form of self-advertising, but also ensuring that their own production methods conform to the highest standards of environmental stewardship, as ratified by third-party audits. Builders engaged in constructing green buildings, certified under IGBC and GRIHA norms, can select the best TMT steel bars manufacturers in Kerala and Tamil Nadu, who also boast of environmental credentials, to contribute to the sustainability quotient of the building, apart from also signaling to the end consumer, especially in the high-end residential segment, that the building was constructed with environmental credentials in mind.
A regional manufacturer leading on sustainability
One of the most established steel manufacturing companies in South India, Bharathi TMT has achieved the prestigious green product certification known as Greenpro. This certification is a symbol of a company’s dedication to ensuring that its manufacturing practices are environmentally friendly. Coupled with the fact that the company uses 100 percent refined steel billets in its manufacturing process and that its product portfolio includes high-end 550D bars that minimize material usage in structural configurations, Bharathi TMT is a shining example that high-quality products and green manufacturing are not contradictory concepts.
Make sustainability structural, not cosmetic
Some builders may choose to install solar panels or energy-efficient fittings to promote a green image, but use materials within their buildings based purely on price. True sustainability begins from the ground upwards. Selecting best quality TMT steel bars in Tamil Nadu or best quality TMT steel bars in Kerala from a supplier that has been responsible in its production, testing, and design for a long life cycle is arguably the most environmentally friendly choice a builder can make. The carbon you save by choosing smart is carbon that’s never even released into the atmosphere in the first place — and that’s a legacy you can build on.
