In construction work, builders use many kinds of materials and equipment. Thermo Mechanically Treated or TMT bars are an essential material used for building purposes in India. Why are these bars preferred for construction works? Their durability and high tensile strength help a concrete structure stay strong for lifetime. Hence, they are so much famous and preferred for constructional work. TMT bars ensure stability and safety to structures.
When these bars have so many positive qualities, it is necessary that one pick the right bar for his structure. Now, when buying these bars, there are certain factors that everyone should keep in mind besides comparing TMT bars price in Agartala, Kolkata and around Bengal. What are those factors? Have a look at the section below.
Essential Factors to Check Before Buying TMT Bars
- Gradation
In this country, there are three grades of TMT steel bars – Fe 415, Fe 500 and Fe 550. Higher the grade means greater is the strength but with higher grades the ductility reduces, which would not be suitable for earth quake prone zone.
- Brand and Certification
This is another very important factor to consider while selecting the right steel bars. One should check BIS certification and its brand reputation. It is always advisable to go for reputed brands having the BIS certification. In other words, one should choose the reputed companies as they even have bars that conform to international standard.
- Manufacturing Technique
Using cold twisted technology for producing TMT bars is now an obsolete method. Modern manufacturing process uses Thermo Mechanical treatment with advanced Tempcore water cooling system. This ensures greater flexibility and strength to the bars. Hence, when buying these bars, ask about the manufacturing process so that one gets the right bar for construction.
- Rust Resistance
This is very important. One should not forget to check how much resistant the bars are to corrosion because corrosion can create serious problems. Often the bars are open to moist condition and therefore, TMT bars need to have corrosion resistance to cater longevity to a structure.
- Bending Ability
Builders might need to bend the bars for construction purpose. If the TMT steel bars are of supreme quality, they will not develop any crack because of bending. Hence, checking for flexibility is a must.
These are certain very crucial factors that everyone should pay attention to while buying TMT steel bars for his structure.
