It is not the beauty of a building you should look at; its the construction of the foundation that will stand the test of time. – David Allan Coe
Moira’s commitment to deliver TMT bars that promise reliability and strength is what builders need to achieve their desired result. As market leaders in the steel and construction business in Central India, Moira’s brand name holds equity and is associated with strength, integrity and reliability.
Moira’s soft-core TMT bars are manufactured using stringent quality processes. As a result, our TMT bars offer superior bond strength, better bendability and fatigue resistance, 100% weldability, and reduced construction time. We use latest German CRS technology that ensures better corrosion resistant characteristics and seismic resistance properties. Our TMT bars are suitable for both compression and tension reinforcement and are thoroughly tested before dispatch. Moira’s TMT bars are ISI certified and each bundle bears the trademark ISI logo along with quality test certificate. At Moira, customer satisfaction and quality product is our key focus. We organise factory visits for anyone interested in understanding our processes. Click here for a factory visit request.
Moira’s commitment to fast delivery ensures that all our orders, small and large, are delivered on time. This reduces the builder’s requirement to keep large stocks, and thus reduces the chances of theft and inventory storing costs. Moira promises round the year stock availability to ensure that the project construction does not get delayed.
Moira TMT bars are available in grades Fe-500, Fe-500 D, Fe-550, and Fe-550 D. While sizes of these bars range from 8mm to 32mm in diameter, bars of diameter 28, 36 and 40 mm are also available, which is not readily available in other local brands. Standard Moira TMT bars are 12 meters in length. We also provide customization of length for large orders and produce Dovel bars on request.
Our widespread network of 400+ dealers ensures a lower lead time thus providing a lower project cost with optimised efficiency. Moira also assists builders in credit extension through its distributors. Since all Moira TMT bars follow ISI specifications, you are guaranteed to get products that are of the precise weights and correct grades.
Moira is a trusted and reputed brand of TMT bars in Central India. Our dedication to achieve customer satisfaction through consistent delivery of quality product has propelled us to be a market leader in the sariya segment in Central India. Usage of Moira TMT bars in projects enhances the consumer appeal of the project and positions it as a superior quality offering by the builder. Builders can therefore rely on Moira for quality products that will prove to be cost-effective with brand association benefits in the long run.
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.
In India, Bureau of Indian Standards is a national organization responsible for maintaining service and quality of products.

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.
