When it comes to building the perfect home, you deserve the right construction material which promises to protect you and your family. Not only do you have to build a strong foundation, but you also have to build strong columns and beams that give life to your house and provide it with the support it needs. Choosing quality branded products for construction ensures that your house is built with reliable material that ensures your hard-earned home will not only last longer, but will also stay strong.
This is why it is important to invest in the right Sariya for your home. Moira CRS Sariya brings you qualities like superior bond strength, better corrosion resistance, and exceptional seismic resistance properties which would provide your home with the necessary strength to withstand harsh weather and earthquakes. Manufactured in hi-tech plants with latest technology, and coupled with our promise to deliver the best to you, makes Moira the ideal choice for your home.
While buying Moira Sariya, make sure to see Moira Sariya brand name written in Hindi on the TMT bar with pink colour at both ends of the bar. Moira bars have a cross-rib (x-rib) pattern in 8, 10, 12 mm sizes. The cross-rib pattern gives the TMT bar better bonding with concrete.
TMT bars give the structure its strength. They are used as reinforcement in concrete and form the core of a construction. TMT bars are thermo mechanically treated steel bars with a hard outer core and a soft inner core. The hard outer core gives the TMT bar its strength and the soft inner core gives high bendability to the bar.
When it comes to picking out TMT bars, there are various grades to choose from: Fe-500, Fe- 550, Fe-500 D, Fe-550 D and Fe-600. Higher the grade of TMT bar, the stronger the housing structure will be. Cost Benefit analysis should be done before selecting a particular grade. Click here to see details of TMT bar grades. TMT bars with higher ductility, bendability, and elongation are most useful in earthquake prone areas, where the building structures need to withstand the seismic pressures. In Indore and surrounding areas, the government recommends using Fe-500 D as these areas are designated seismic zone 3.
Higher bendability in TMT bars is a great advantage. TMT bars are required to be bent and moulded into various shapes as per requirements at construction sites. Higher bendability ensures ease of use at construction site without breakage in the product. The ideal TMT bar should be flexible, and hence should develop no cracks even if it is bent at an angle equal to or higher than 90 degrees. Bendability in TMT bars can be tested by doing a Mandrel Bend Test. In this test a TMT bar sample is tested on a bending machine to see if any cracks appear on the sample. The size of mandrel is decided based on the TMT diameter. The process to decide the size of mandrel is a simple calculation, TMT bar diameter * 5 = Mandrel diameter. Example, to test 8mm TMT bar (8 * 5 = 40), 40mm mandrel should be used.
The more difficult it is to bend the TMT bar, the better it is. If correct size of mandrel is used and the TMT bar cracks, then the TMT bar quality is poor. However, if the TMT bar cracks on using incorrect mandrel size, then TMT bar quality is not the issue, the mandrel size used is wrong.
Building structures are designed by architects with specific ISI TMT bar specifications as they provide structural strength to the building. Buying underweight TMT bars can be detrimental to the building structure. Using an underweight TMT bar will lower the strength of the structure and compromise its safety. Consumers can check whether the TMT bar they are buying is of standard weight as specified by Bureau of Indian Standards by referring to the table below with ISI specification. In case the weight is less than the specification, it is not ISI compliant. In case the weight is more than specification, a consumer ends up paying more for extra weight over and above the specification.

Salt corrosion test is performed to check rusting. A TMT sample is half tied in a polythene, while the other half is left open. It is then immersed in salt water, usually for a period of 96 hours, and is then kept in the open for a few days to see how soon rust is formed on the TMT bar. TMT bar with low corrosion resistance will rust.

Using TMT bars of Fe-500 grade instead of Fe-415 grade leads to up to 20% savings on material thus leading to a saving in the amount spent on buying TMT bars. The difference in the strength between Fe-415 and Fe-500 grades is 20%, Fe-500 being 20% stronger than Fe-415. The reason for this is as follows:
Fe-415 denotes that a force of 415 N/sq.mm. is required to deform the TMT bar, whereas Fe-500 denotes that a force of 500 N/sq.mm is required to deform the TMT bar. The difference in the strength between Fe-415 and Fe-500 grades therefore is 20%.
This gives Fe-500 a superior structural strength than Fe-415 and therefore lesser number of Fe-500 TMT bars are required to hold the structure as compared to Fe-415. For instance, if a structure requires 1 ton of steel, which costs Rs 50,000 for Fe-415, then Fe-500 grade would require, 0.8 ton of steel, which would cost Rs 40,000 leading to a saving of Rs 10,000 per ton. Unlike other brands which claim to manufacture Fe-500 while actually manufacturing Fe-415, Moira guarantees it’s Fe-500 grade TMT bars are 100% genuine.
