One of the usual concerns when working on a construction project is the quality of the material and construction. Urban construction today boasts lucrative features like multi-faceted designs suited to the regime and needs of its users, spectacular architecture and incredible height. So many of these construction projects are located in seismic zones or zones which are prone to natural disasters. While it is not possible to avert these calamities, it is possible to mitigate the loss of life and property in case of a natural disaster.
TMT bars are a game changer when it comes to increasing the structural integrity of any construction. Read on to discover how TMT bars provide stability and strength to urban structures and skyscrapers to bear nature's brunt.
TMT bars or Thermo mechanically treated bars go through a thermo-mechanical process to make alternatives of different grade steels with broad applications. This process in TMT bars applies ineffectiveness by developing a heat slant between the cooler surface and the new inner core. As a result, TMT bars have a more rigid outer surface with higher durability and a softer inner core for better tensile strength. This process ensures higher corrosion resistance in the rods, superior weldability and higher ductility. These TMT bars can be readily welded to produce the best results, allowing the architects to develop different structures.
How are TMT Bars instrumental in protecting constructions against Natural Disasters?
1. Fire: - Fire is the most destructive natural disaster which disturbs the structure, stability and durability of a building. No wonder the fire safety of any building is the topmost priority for all engineers and builders. TMT bars have a higher thermal capacity and can withstand a temperature up to 600 degrees Celsius. High fire resistance makes TMT rods perfect for providing safety from fire.
2. Rain: Floods can cause significant corrosion to a structure due to prolonged water exposure. TMT bars protect the buildings in humid environments like coastal areas, underground areas and marine constructions. The unique manufacturing process of TMT bars offers them high resistance to corrosion and high durability against flood water forces. TMT bars are also ideal for construction in water-exposed areas since they do not need further cold twisting to make them corrosion-resistant.
3. Earthquakes: - The pearlite core of the TMT bars gives them high ductility and fatigue confrontation to tolerate dynamic loading and helps a structure absorb the vibration and shock waves caused by earthquakes, minimising damage. Hence it makes sense to use TMT steel rods that are made for use in earthquake-prone zones.
4. Storms: Heavy winds like hurricanes, cyclones, and tornadoes can cause immense damage to buildings and threaten life and property in and around. Using TMT bars can help you fight off the damages because of their strength, fatigue resistance and bendability.
Whether building an individual house or a multimillion-dollar skyscraper, TMT bars play a vital role. They are used in beams, columns, slabs, pillars and other structures. TMT bars are used to provide strength to the building.
However, there are various types of TMT bars available in the market. It would help if you learned about them to be able to decide which one suits your project the most.
Fe 415 –
This is the lowest grade of TMT bars used for reinforcing small-scale construction projects like residential homes and apartments. Because of their uniform elongation property, they are also used in earthquake-prone areas.
Fe 500 –
The most prominent of all TMT bars, Fe 500 are the standard bars widely used in construction projects of varied scales ranging from residential to commercial to multi-storied buildings. These bars' tensile strength and ductility are higher than Fe 415, providing better stability and load resistance.
Fe 550 –
These bars are used in constructing larger infrastructure projects like bridges, industrial plants etc.
Fe 600 –
These TMT bars are used where the construction demands high load bearing, durability and corrosion resistance, like highways, metros and power plants.
One of the essential points to ensure while buying TMT bars is quality. Buy from brands whose bars are certified by the International Standards Organisation (ISO), which is a marker of top quality. To ensure that you buy genuine TMT bars, check for the manufacturer's identification mark on the bars. The carbon content of the bars should be lower than 0.25 to be corrosion-resistant. Higher carbon content decreases the life of the building.
