Are you planning your next construction project? You should then consider investing in good-quality construction materials, especially TMT bars. Good quality construction materials are crucial to stand the test of time. TMT bars are essential to making strong structures, which is why they have rightly replaced conventional bars. Before taking any step in your construction project, consider reading the article because it helps you understand why TMT bars are a game changer in the construction industry.
Why do TMT bars make a difference?
TMT bars are game changers in the industry as their strength is developed during their manufacturing process itself! Manufacturing of TMT bars uses Thermo Mechanical Treatment which involves advanced techniques like self-tempering and quenching procedures. When the bars come out of the mill, they are sent to a cooling process that cools down the exterior of the TMT bar, making it tougher, while the interior of the TMT bar stays hot. This process is called self-tempering, as the temperature of the core tempers the exterior.
· Prevents the structure from collapsing during natural calamities:
This manufacturing technology makes the exterior of the TMT bars tougher and the interior softer. Appropriately treated TMT bars exhibit massive strength at the exterior and flexible interior. This
soft inner core helps absorb shock and prevents tension from radiating along the structure. Natural disasters like earthquakes can cause severe stress to the structure of a building. If you fear structural integrity, you should consider investing in TMT bars.
· Enables easy transportation and ensures structural integrity:
Do you know that when bars catch rust, it leaves cracks in the buildings? Also, handling and transporting the bars can be problematic when they are not rust-resistant. They also require specific temperature conditions for storage and during transportation and construction. Consider other external threats to a building, such as rain, flood, and fire. You should enhance protection against these odds to ensure the integrity of the building.
As marine structures and buildings in coastal areas need more protection against humidity, they prefer TMT bars. TMT bars that had undergone Thermo mechanical treatment create a uniform and thickly tempered martensitic rim. The bars get treated with rust-resistant chemicals like Sulphur, Copper, carbon, and phosphorus as well, thus ensuring safe and easy transportation.
Let’s learn about manufacturing technology:
The Thermo mechanical treatment of steel qualifies them for superior construction purposes. When steel bars undergo the Thermo mechanical treatment, the bars come out with superior strength.
The Thermo mechanical treatment involves three successive stages in the course. The three distinctive stages are plastic deformation, quenching, and self-tempering. These effective procedures ensure standardized mechanical properties required for the construction industry.
· The quenching process increases the bars’ tensile strength, ductility, and weldability. This process hits the surface of the bars and helps deform the internal crystal structure.
· The self-tempering process involves the constant heat flow from the core to the surface, where the bar’s core remains hotter. This process converts the brittle martensite into tempered martensite.
· The atmospheric cooling process focuses on the core of the bars. The process involves tempering the core. This tempering of the core ensures the right blend of ferrite and pearlite core and thus increases strength and flexibility.
After the Thermo mechanical treatment, the process involves straightening the bars, and then cutting them into desired lengths. These bars are now sent for quality inspection, where they get tested for physical and chemical properties.
Hence the manufacturing technology makes all the difference concerning the strength of the TMT bars. Therefore, as you approach any Supplier of TMT bars, check their manufacturing procedures before the purchase.
Why do we need Thermo Mechanical Treatment?
When bars undergo the Thermo Mechanical Treatment, they bring in unmatched advantages. It also makes these bars suitable for all kinds of construction.
· Economical: Thermo Mechanical Treatment is an economical process. It can save about 17% of the steel and is available at lower rates than other steel bars.
· Unmatched advantages: TMT process brings in superior qualities. They include elongation, better tensile strength, flexibility, and bendability. The chemical treatments also add features such as fire-resistance and corrosion-resistance properties to the bars. These features enable them to use the TMT bars in various construction structures.
· Advancement in features: This advanced Thermo Mechanical Treatment makes the bars superior in standard. With this treatment, bars include alloys like martensite, ferrite, bainite, and perlite and become 20% more robust than untreated steel.
Choose TMT bars based on your requirements:
If your construction project is a multi-story commercial or residential building, you could choose Fe 500 grade as it has higher seismic ability and flexibility.
Manufacturers make these specifically for high-rise buildings. Thus they focus on higher flexibility and stability. Are you worried about sudden loads and earthquake activities? You should invest in Fe 500 grade.
If you are looking for construction materials with a more tensile strength that applies to diverse requirements, Fe550 is the right choice. Fe550 is perfect for large-scale, industrial, and infrastructural projects and offers a higher strength than Fe 500.
Prefer Fe550 bars for underground construction and marine and coastal areas with a higher risk of breakage due to humidity.
Are you worried about fire hazards? You should choose TMT bars with higher thermal stability. The TMT bars can withstand temperatures up to 600 degrees Celsius. This vital property has convinced hospital construction and other crucial projects to adopt TMT bars.
The diversity and technical advancements have made TMT bars the default option for every project, such as Residential projects, High-rise buildings, Industrial structures, office buildings, Dams, flyovers, large structures such as Malls, schools, airports, and even underground and underwater structures.
Conclusion:
The increasing investment in the construction industry and innovative structural designs have increased the industry’s standards. With the Thermo Mechanical Treatment of steel bars, the manufacturers can lower the carbon content and reduce the impurities such as sulfur and phosphorus, thus making the TMT bars durable and long-lasting. Therefore, many advantages mentioned above make TMT bars a massive hit in the construction industry
