Although steel and concrete are two different materials, they have to behave as a single unit in a reinforced structure. This can happen only when the concrete grips the steel TMT bar to form the strongest bond through unique rib pattern of the TMT bar. Moira TMT Bars have distinct cross-rib (x-rib) pattern which gives them double the strength of an ordinary bar. The ribs are made using CNC notch cutting machines. This ensures uniform rib pattern for 100% of the TMT bars that allows strong bonding with concrete for the whole structure. This is in contrast to the ordinary sariya where ribs are manually cut, which always leaves scope for non-uniform rib pattern and thereby non-uniform and weaker bonding throughout the structure. Due to uniformity and critically designed ribs, fatigue strength of Moira Sariya is significantly superior to ordinary sariya.

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. Moira TMT bar can be bent easily and sharply. Moira CRS Sariya can be bent to the exact angle unlike ordinary sariya as desired by the design around mandrels, specified in IS:1786. The special micro structure of Moira Sariya results in a TMT Bar with excellent bendability.

Due to its high weldability, Moira Sariya can be welded into various shapes thus giving architects and designers the freedom to innovate without compromising on the strength of the structure. Moira CRS Sariya, due to its low carbon equivalent, has a weldability which is superior to ordinary sariya. It can be butt-welded or lap-welded using ordinary rutile coated electrodes of matching strength. In manual arc welding, no pre-warming or post heat treatment is necessary.

Corrosion resistance in TMT bars is a critical factor in construction. TMT bars carry bulk of the load of a structure and protect it against cracking. Corrosion in the TMT bar can compromise the strength of the structure. We take several measures to ensure superior corrosion resistant properties in our product. Our manufacturing process comprises addition of copper, nickel, and chrome to the raw material. This gives Moira TMT bars higher corrosion resistance than other TMT bars manufactured by primary and sponge iron-based plants. Additionally, the composite and uniform microstructure of Moira TMT bar gives it superior corrosion resistant properties as compared to ordinary TMT bars while being embedded inside concrete. Our TMT bars undergo rigorous tests to check for rusting through stringent salt corrosion testing methods. The samples are immersed in salt water and are then left to dry which reinstates assurance of our products’ quality standards.

Seismic resistant properties are critical in construction. The addition of manganese results in higher ductility of Moira TMT bars as compared to ordinary bars, thus making it earthquake resistant. Higher ductility ensures that the bar is able to elongate to a larger extent and therefore withstand high stress during an earthquake, protecting the structure. Several studies were conducted on concrete beam column joints reinforced with Moira CRS TMT Bars to evaluate its performance under repeated reversed loading with large deformations as would be encountered during an earthquake. It was found that the energy dissipation was almost same for each cycle in all of the studies, indicating uniformly maintained ductility of Moira TMT bars in repeated stress cycles. These studies reinforce the superior earthquake resistant properties of Moira TMT bars.
